Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process management support device for a building construction used for performing a process management for various individual constructions accompanying a construction of a house or the like with high precision and accuracy within the entire construction period, and And a computer-readable recording medium on which a process management support program is recorded.

[0002]

2. Description of the Related Art Conventionally, in the construction of buildings of this type, construction companies receiving requests from the owner generally use a large number of subcontractors to perform foundation work, woodwork, exterior work, interior work, equipment work, and the like. In this form, various individual works are performed. In these cases, the process management of various individual works is mainly based on the experience of giving instructions on the delivery of materials for the next process, execution dates, etc. in order based on the actual progress of the individual works and many years of experience. Generally, process control based on rules is adopted.

[0003] A critical path method (CPM: Crit) is used as a process control method for large-scale civil engineering work.
ical Path Method) is also known. In the case of this method, the cost of various individual works is assumed to be proportional to the time required for each individual work (construction period) based on the constraints such as the order of execution. Is represented by an arrow diagram, that is, the process schedule in which the overall construction period is minimized, and the process management is performed so that various individual works proceed according to the process schedule. In general, the above-mentioned process chart based on the arrow diagram is manually created on a desk, and it is also possible to use a display device of a computer to draw various data on the display device by manually inputting various data. Have been done.

[0004] Further, there is a program for creating a process chart used for process control for building construction using a computer. In this program, various individual works associated with building construction, a standard work period predetermined as a work period of each work, and a process order rule that defines constraints such as a priority execution order of various individual works are previously stored and stored. When the program is read by the computer, the following processing is executed. In other words, the operator uses this computer for initial data such as the subcontractor to be employed and the work rules of the subcontractor, such as holidays, and the scheduled start date, scheduled completion date, floor space, number of rooms, roof shape for concrete buildings. By inputting the due date data and the work quantity for each individual work based on the above, etc., the various individual works rearranged according to the above process order rules are displayed on a display device etc. with the above-mentioned standard work period arranged in the time axis direction. Output. In other words, since the standard construction period for various individual works is fixed beforehand, the various individual construction items are re-arranged along with the specific dates such as the above-mentioned start date, and the contractor and contractor Etc. are displayed.

[0005]

However, in the process control based on the conventional rule of thumb described above, each individual construction is individually dealt with, and it is completely uncertain what time the construction completion date will be finally. It becomes something. In addition, delays in the previous process appear as uncertainties in the ordering and delivery of materials necessary for each process after the next process, and the start of subcontractors, and the completion date of construction is accelerated later than the above delay. become.

When a process chart is created using the above-mentioned CPM, whether it is created on a desk or by using a computer, all of the creation is performed manually by the creator. In addition to the complexity of having to perform the process, it is necessary to re-create the process when the process delay occurs in the middle of the process, but it is necessary to perform the complicated process again. And while such arrow diagrams are convenient for grasping the flow of the entire process, it takes too much time to manage the process by incorporating all the various complicated processes involved in building construction. There are inconveniences.

Furthermore, when the process schedule is created using the above-mentioned computer program, since the standard construction period of each individual work is fixedly set in advance, the change of the process itself and the individual work of each individual work are performed. There is an inconvenience that the construction period cannot be flexibly changed according to the individual site environment or the like. In other words, if the construction site of the building is on a narrow land, vehicles for carrying in materials cannot enter, etc.
In addition to the effects of delays in the construction period due to the difficulty of work based on the specific site environment, it is not possible to take into account the effects of the work schedule. The process management cannot be flexibly changed according to the delay factors such as the on-site environment and weather fluctuations. Therefore, taking into account such delay factors, highly accurate construction period prediction,
There is an inconvenience that it is not possible to carry out high-precision process management that can perform reliable construction period management.

The present invention has been made in view of such circumstances, and it is an object of the present invention to be able to actually realize it in consideration of various factors with respect to a concrete construction period for building construction. It is an object of the present invention to provide a process management support device for realizing process management capable of completing building construction with high accuracy and a computer-readable recording medium recording a process management support program.

[0009]

In order to achieve the above-mentioned object, the present inventor assigns the distribution of the extra days, which is the difference between the desired setting period and the theoretically shortest period ignoring delay elements, to various individual works. Focusing on the need to perform flexible and optimized process management by taking into account individual and specific delay factors in concrete building construction, as a method, it depends on weather fluctuations and the physical environment of the construction site etc. Various delay elements are evaluated numerically as the risk of construction delay evaluated numerically, and the above-mentioned extra days are devised to be allocated according to the value of the risk of construction delay. This is applied to a process management support device to be used.

More specifically, a first aspect of the present invention provides a process management support apparatus for building construction in which a computer to which an input device and an output device are connected supports the process management for building construction. According to. In the first invention, it is a specific matter that the first invention includes the following first and second storage units and first to fourth processing units. That is, the first storage means stores weather statistics data relating to rainfall, standard stepping data for each individual construction necessary for construction of the building, and a process order rule that defines restrictions on the execution order of the various individual constructions, It is assumed that basic information including the first construction delay risk degree in which the risk of occurrence of delay is quantified in advance based on an empirical rule for each individual construction work is stored and stored in advance. As the second storage means, the construction area, the planned construction start date and the desired completion date, the number of workers to be put in each of the above individual works, and It is assumed that unique information on the specific building, which includes the construction target quantity and the second degree of construction delay risk quantified according to the site environment of the specific building, is stored and held in an updatable manner. The first processing means calculates the required number of actual working days for each individual construction based on the planned number of workers and the construction target quantity for each individual construction and the standard walking data taken out from the first storage means. The total number of required actual working days shall be subtracted from the desired overall construction period based on the planned start date and the desired completion date to determine the overall spare days. The second processing means performs third construction delay due to weather change based on weather statistics data corresponding to the construction area and construction date of the concrete building extracted from the weather statistics data stored and stored in the first storage means. The risk is determined, and the concrete work delay risk for each individual work is determined by adding the third work delay risk and the second work delay risk to the first work delay risk. The third processing means individually allocates the entire spare days to the various individual works so as to increase as the specific construction delay risk increases, and adds the allocated individual spare days to the required actual working days. The assumed individual construction period for each individual construction shall be determined. And the fourth
The processing means corresponds to each of the various types of individual work on the orthogonal table in which the axis of the desired overall work period is displayed on one axis and the individual work items rearranged in the order of priority of the process order rule are displayed and set on the other axis. A process chart in which the assumed individual construction periods are displayed by a linear symbol or a bar-shaped symbol so that the respective construction periods of the various individual construction types in the above-mentioned priority order are consecutive before and after is output to the output device.

In the case of the process management support device according to the first aspect of the present invention, the specific information on the concrete building, that is, the construction area, the scheduled start date or the possible start date from the start date of the construction is requested by an input device such as a keyboard. The desired total construction period, the number of workers scheduled for each individual construction, the number of works to be constructed for each individual construction, and the work difficulty based on the site environment are entered. The information is updated to the specific information on the concrete building to be managed. Thus, first, the first processing means calculates and determines the total number of spare days, while the second processing means sets the first criterion which is the evaluation criterion of the delay occurrence prediction set for each individual construction.
Calculate the concrete work delay risk for each individual work by taking into account both the second and third work delay risks, which are the evaluation criteria of the delay occurrence prediction based on the actual construction site and construction time, for the work delay risk It is determined. Next, the entire spare days are allocated by the third processing means for each individual construction in accordance with the value of the specific construction delay risk, and the required actual working days are added to the allocated individual spare days to obtain various individual construction days. The assumed individual construction period for each is determined. Then, a process chart in which the assumed individual construction period corresponding to the orthogonal table having the due date and various individual construction items as coordinate axes by the fourth processing means is displayed by a linear symbol or a bar symbol is output to an output device such as a display or a printer. Based on this process chart, it is possible to perform flexible and practically feasible process management that takes into account various delay factors such as weather fluctuations and the site environment of concrete buildings. On the other hand, accurate construction period management becomes possible.

Here, the input of the construction target quantity for each specific construction for the concrete building section into the second storage means is C
Connect an AD (Computer Aided Design) device and
The above-mentioned CA receives the input command for the construction target quantity calculated by the AD device based on the CAD data for each of the above individual constructions, for example, the target area for the foundation work, the roof area for the roof construction, etc.
You may make it take in automatically from D apparatus. This makes it possible to effectively utilize the design data performed by the CAD device, and at the same time, it is possible to save labor when the operator manually inputs individual information on the specific building individually.

In the determination of the concrete construction delay risk in the second processing means, the first construction delay risk stored and stored in the first storage means is determined for each individual construction by its unique factors, site environment and weather. It is determined in advance based on an empirical rule for each of the various delay factors of the variation, and the first construction delay risk for each delay factor is multiplied by the second and third construction delay risks for the concrete building. It may be. The above-mentioned specific factors include, for example, whether or not a difference between the estimate of the number of works to be constructed in each individual construction and the actual construction is likely to occur, and whether or not rework due to defective construction is likely to occur. For example, there are factors such as whether the individual works are easily affected by the margin of the site, and whether there is a width of the front road where the materials can be directly carried in, etc. For example, as in the case of outdoor construction, there is a problem caused by whether or not it is easily affected by rainfall. For each of these delay elements, the degree of susceptibility to each individual construction according to the characteristics of the individual construction is determined in advance as a first construction delay risk by several numerical values. By multiplying each of the second and third construction delay risks, which are the risks to the occurrence of delays inherent in the construction of concrete buildings, such as weather fluctuations, etc., for each individual construction, The degree of danger taking into account all the various delay elements is obtained as the specific construction delay danger. As a specific example of the setting of the first construction delay risk, for example, those having a low risk of occurrence of delay, that is, “0”, “1”,
A three-step numerical value such as “2” may be set.

Here, for example, monthly rainfall probabilities for each prefecture are input in advance as weather statistical data stored and stored in the first storage means, and in the second processing means, a specific building construction area is determined. The rainfall probability of the month to which the corresponding construction date of the prefecture belongs may be directly determined as the third construction delay risk. In addition to the rainfall probability, a monthly average rainfall amount for each prefecture may be input in advance as weather statistical data. In this case, the magnitude of the average rainfall value is divided into, for example, three ranges, and the numerical values “0”, “1”, and “2” are set as the third construction delay risk in order from the range with the lowest rainfall. Just set it. Furthermore, the second construction delay risk due to the “site environment” as a delay element may be quantified from the viewpoint of the work difficulty based on the site environment. In other words, it is only necessary to input the degree of difficulty in achieving material delivery, the degree of difficulty in executing work, and the like. Difficulties in achieving the above material delivery include whether or not it is easy to carry in materials based on the width of the front road,
For example, it is determined whether there is a large traffic volume on the surrounding roads and delays occur in the delivery of materials and the arrival of workers at the site. In addition, the difficulty in performing the work is based on the above-mentioned site margin, for example, due to the site margin that the site area is small and it is difficult to secure a work space, or when individual works are performed indoors. And whether the work is an outdoor work, that is, whether the work is easy to perform or not. Then, the difficulty levels of these operations are set to “0”,
For example, numerical values in three stages such as “1” and “2”
What is necessary is just to set it as a construction delay risk. In such a case, the larger the numerical value of the concrete construction delay risk is, the higher the possibility of the construction delay is. Therefore, the third processing means allocates more spare days as the possibility of the delay is higher. By doing so, process management that can be actually realized becomes possible.

When determining the specific construction delay risk, the following delay elements may be digitized, and the specific construction delay risk may be determined in consideration of the numerical values. For example, difficulties in obtaining materials (for example, seasonal fluctuations in stocks of material manufacturers), the influence of the quality of skills of subcontractors ordering various individual works, design changes or poor construction as factors determined by experience occur. Whether the construction is easy (delay due to redo due to design change or construction failure), whether the construction requires a crane (delay due to crane arrival delay, inability to work due to strong wind, etc.), and the effect of seasonal fluctuations in workable time (sunrise·
A delay factor such as seasonal variation in sunset time) or the importance of each individual construction (whether the construction is a basic construction, or whether the construction is closely related to the construction of the next process) may be added.

Further, as a process order rule stored in advance in the first storage means, a priority order for executing various individual works, for example, it is necessary to finish a basic work before performing a wood work. And the like. In addition to this, a rule on whether or not simultaneous execution is possible in various individual works may be included. When there are individual works that can be executed simultaneously, only the maximum required actual work days of the plurality of individual work pieces that can be executed simultaneously is counted as the total value of the required actual work days in the first processing means. What should I do?

A second invention relates to a computer-readable recording medium for recording a process management support program for building construction to be executed by a computer. The recording medium has the following storage unit. It is a specific matter that a process support management support program for causing a computer to execute the processes of the first to fifth steps is recorded. That is, in the storage unit, weather statistics data on rainfall, standard walk data for each individual construction required for building construction, a process order rule that defines restrictions on the execution order of the various individual constructions, and Basic information including the first construction delay risk degree in which the danger of occurrence of delay for each of the various individual works is quantified in advance based on an empirical rule is stored. Then, as the processing of the first step, for each concrete building to be constructed, the construction area, the planned start date and the desired completion date, the number of workers to be put into each of the above individual works, the number of works to be put into each of the above individual works In addition, unique information including the second construction delay risk quantified according to the site environment of the specific building is input and stored and updated. In the process of the second step, the required actual number of working days for each individual construction is calculated based on the input planned number of workers and construction target quantity for each individual construction and the standard walking data retrieved from the storage unit. Then, the total value of the required actual working days is subtracted from the desired overall construction period based on the planned start date and the desired completion date to determine the overall spare days. In the processing of the third step, the construction area and construction date corresponding to the specific building input in the first step are extracted from the weather statistics data stored in the storage unit, and the extracted weather data is extracted. The third construction delay risk of the concrete building construction due to weather fluctuation is determined based on the statistical data, and the third construction delay risk and the second construction delay risk are added to the first construction delay risk. Determine the specific construction delay risk for each individual construction. 4th
As the processing of the step, the total spare days are individually allocated to the various individual works so as to increase as the specific construction delay risk increases, and the allocated individual spare days are added to the required actual working days and various Determine the estimated individual construction period for each individual construction. Finally, as the process of the fifth step, the orthogonal table in which the date of the desired whole construction is displayed on one axis and the individual construction items rearranged in the order of the priority of the process order rule on the other axis are respectively set in the orthogonal table. A process chart is output to the output device, in which the assumed individual work period corresponding to each individual work is displayed by a linear symbol or a bar-shaped symbol such that the respective work periods of the various individual work items in the above-mentioned priority order are consecutive before and after.

In the case of the second invention, by causing a computer to read the process management support program recorded on the recording medium, the computer can execute the processing based on the first to fifth steps. Will be possible. That is, in the first step, when the same specific information as described above about a specific building is input via an input device such as a keyboard, first, the total number of spare days is calculated and determined in the second step. 3
In the step, the second and third works are evaluation criteria of the delay occurrence prediction based on the actual construction place and the construction time with respect to the first construction delay risk which is the evaluation criteria of the delay occurrence prediction predetermined based on various delay elements. The specific construction delay risk for each individual construction taking into account the delay risk is calculated and determined. Next, in the fourth step, the total spare days are allocated to each individual construction in accordance with the value of the specific construction delay risk, and the required actual working days are added to the allocated individual spare days to obtain various individual construction works. The assumed individual construction period for each is determined. Then, in the fifth step, a process chart in which the assumed individual construction period corresponding to the orthogonal table having the date and various individual construction items as coordinate axes is displayed by a linear symbol or a bar symbol is output to an output device such as a display or a printer. Based on this process chart, it is possible to perform flexible and practically feasible process management that takes into account various delay factors such as weather fluctuations and the site environment of concrete buildings, based on this process schedule. Accurate construction period management becomes possible.

Also in the second invention, the input of the construction target quantity for each individual construction in the specific information on the concrete building section in the first step is performed by CAD.
(Computer Aided Design) Connect the device to a computer, and input the work target quantity calculated for each of the above individual works by this CAD device, such as the target area for foundation work, the roof area for roof work, etc. in the first step. In response to this, the data may be automatically imported from the CAD device. This makes it possible to effectively utilize the design data performed by the CAD device, and at the same time, it is possible to save labor when the operator manually inputs individual information on the specific building individually.

Further, what is used as the weather statistical data stored and stored in the storage unit, how the third construction delay risk is determined using the data, and the second construction delay risk according to the site environment are determined. How to do the digitization, and
The above process management is used to determine how to calculate the concrete construction delay risk using each of the third construction delay risks, and how to allocate the total spare days based on the specific construction delay risk. The same processing as described in the support device may be performed.

Further, as the process order rules stored in the storage unit, in addition to the priority order for executing various individual works, a rule on whether or not simultaneous execution is possible among various individual works is included. In this case, only the maximum required actual working days of the plurality of individual works that can be executed simultaneously may be totaled as the total value of the required actual working days in the second step.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an overall configuration diagram including a process management support device according to an embodiment of the present invention, wherein 1 is a so-called personal computer having a built-in micro-processor,

Is a printer as an output device, 6 is a CD-ROM as a recording medium, 7 is a personal computer with a built-in microprocessor, and 8 is a display connected to the personal computer. The personal computer 7 and the display 8 constitute a part of a CAD apparatus for automatically calculating a building and automatically calculating a construction target quantity such as an area and quantity of each part.

As shown in FIG. 2, the personal computer 1 includes a first storage unit 11 and a second storage unit 12 as a storage unit 10, and first to fourth processing units as a processing operation unit 13. 14 to 17 are provided. Each of the first to fourth processing means 14 to 17 is constituted by a processing operation unit of a process management support program installed in advance, or reads the process management support program recorded therein from the CD-ROM 6. It consists of. In addition, as the recording medium, the above C
In addition to the D-ROM 6, other media such as a floppy disk 6 'may be used.

Various basic information is previously input and stored in the first storage means 11. The following data is stored and stored as basic information.

That is, weather statistical data, sunrise / sunset time statistical data, a calendar covering a plurality of years (for example, 10 years), standard step-by-step data for all types of individual works required for building construction, various individual A list of subcontractors for each work, a list of suppliers of materials, a process order rule for the execution order of various individual works, a first work delay danger to the occurrence of delay determined for each individual work, and the like are stored and stored in advance as basic information. I have.

Here, as the weather data, a monthly rain probability, for example, a rain probability of 10 mm or more, is stored and stored for each region (eg, each city) in Japan. The weather data and the statistical data on the sunrise and sunset are obtained from, for example, a “science chronology” (published by Maruzen Co., Ltd.). The calendar is used for determining and setting a construction suspension date (for example, Sunday) within the entire construction period. The standard gait data is determined in advance based on past performance data on various individual works. The subcontractor list is information (name, address, contact information, etc.) about contractable contractors existing in each region of Japan. Similarly, the material supplier list is information on manufacturers / distributors or distributors that can deliver materials necessary for various individual works. The above-mentioned process order rules define restrictions on the execution order in executing various individual works, for example, a priority order before or after and a rule as to whether or not simultaneous execution is possible.

The first construction delay risk may be determined based on the characteristics of each individual construction, whether the construction is likely to be delayed or not, and various factors such as delaying the individual construction. The degree of whether or not the delay element is easily affected, that is, whether or not the delay is likely to occur is quantified in advance based on an empirical rule. In other words, the criterion for the risk of occurrence of delay is determined in advance. Specifically, the delay factors include the process delay risk based on the characteristics of the individual works described above, the site margin risk based on the site margin, the front road risk based on the width of the front road at the construction site of the building, and rainfall. In this case, four types of rainfall impact risk due to the influence of the above are set, and the four types of delay elements are evaluated for each of the above-mentioned individual works. For example, the process delay risk may be set to “0” for those that are not easily delayed, “1” for those that are slightly delayed, and “2” for those that are easily delayed (for example, construction requiring crane work). . Similarly, as the site margin risk, “0” is given to those that are not affected even if the margin of the site with respect to the construction area is small, “1” is sometimes given, and “2” is given to those that are affected. ”Is set as the front road risk,“ 0 ”is set for those that are not affected by the width of the front road,“ 1 ”is set for those that may be affected, and those that are affected (for example, Work), set "2" for each
As the rainfall impact risk, it is good to set “0” to those not affected by rainfall (for example, indoor construction), “1” to those that may be affected, and “2” to those affected. .

The above-mentioned various works include start work, foundation work, wood work, exterior work, interior work, equipment work, and end work, which are broadly classified. There are individual works of sub-classification. For example, signage and temporary enclosure installation, temporary toilet installation, temporary electric installation, and each individual work such as temporary water supply installation as belonging to the above-mentioned start work, leveling-base concrete casting as belonging to the above-mentioned foundation work, There are a number of individual works, such as individual works for piping sleeves, rebar sets-backfilling, foundation piping, and finishing.

Next, each processing by the first to fourth processing means 14 to 17 will be described with reference to FIG.

(Steps S1 to S3) First, as a prerequisite for the start of each processing by each of the above processing means 14 to 17, it is a condition that specific information on a concrete building to be constructed is input. Therefore, in step S1, an input instruction is displayed on the display 4 so as to input the unique information. Based on this, the operator inputs in a step S2 the unique information necessary for performing each of the above-mentioned processes in an interactive manner for each data to be input to the display 4, and the input unique information is stored in the second storage means 12 Is stored. At this time, if unique information about another property or the same specific building is stored, the information is rewritten and updated with newly input unique information.

Here, the above-mentioned unique information is various data as described below. In other words, the construction area (for example, a city) of the concrete building, the scheduled start date and the desired completion date, the subcontractor employed for each individual construction, the holidays and working hours of the subcontractor, and various individual works for the subcontractor The number of days required for the arrangement, the number of suppliers to be used for the materials, the number of days required for ordering and specifying delivery to the material suppliers, the number of workers to be entered for each individual construction,
The number of construction objects for each individual construction (for example, the number of units used in the standard walk-in data such as area) and the construction objects such as the second construction delay risk set according to the site environment of the above specific building Is information specific to the concrete building.

The input of the subcontractor employed above is
The subcontractor list stored in advance in the first storage means 11 may be input individually,
To select the subcontractor to be employed from the displayed subcontractor list, and click the mouse 3 with the cursor positioned at the name of the subcontractor to input the subcontractor to be employed. Is preferred. The number of days required for the arrangement to the subcontractor is the data required to create various management sheets created after the completion of the below-mentioned schedule, and several days before the construction start date based on the above-mentioned schedule. Enter with a minus sign if you need to make an arrangement. Similarly, the number of days required for ordering and specifying delivery to the above-mentioned material supplier is also data required to create the various management sheets described above. Enter with a minus sign if you need to

The number of workers scheduled to be put in for each of the individual works is calculated, for example, in a state where the standard attendance data stored in the first storage means 11 is displayed on the display 4 as a table for each of the various works. What is necessary is just to input into the table of the display image for every corresponding individual construction. Similarly, as for the construction target quantity for each of the above-mentioned individual works, a display 4 displaying a table of standard attendance data and the number of workers to be put in for each of the above-mentioned individual works.
What is necessary is just to input together with the display image of. By doing so, the calculation of the required actual working days for each individual construction performed in the next step S4 may be automatically performed by a spreadsheet process. On the other hand, the input of the above construction target quantity is not input by the operator himself,
It is preferable to input automatically by taking in CAD data automatically calculated by a CAD device for automatically designing a building. In such a CAD apparatus, the quantity calculation for each part is automatically performed for estimation after the automatic design, and the result of the quantity calculation is stored and held.
In this case, the computer 7 of the CAD device is connected to the computer 1 of the process management support device, and the data acquisition result set in the display image is clicked with the mouse 3. The number of works is taken in the display image and displayed. Therefore, if the operator inputs the number of workers to be put in, the necessary actual working days for each individual construction are automatically calculated based on the standard attendance data and the construction target quantity. become.

The second construction delay risk is the risk of occurrence of a delay expected according to the specific situation of the site environment of a concrete building, and is the delay element used for setting the first construction delay risk. Two items were selected for the site margin and front road width, especially those that correspond to the site environment from within, and the risk of delay expected from the concrete situation of the building with these site margin and front road width was quantified. It was done. Specifically, the actual site margin condition of the concrete building is “0” if the site is large and has room, “1” if the site is slightly narrow, and the site is narrow. In some cases, “2” is set, and “0” is set if the front road condition is wide and there is enough room for material loading, etc. "1" is set, and "2" is set when there is no margin and there is a problem. In each case, the larger the value, the higher the risk of delay in construction. If the input of the second construction delay risk is, for example, the site margin, the input image displayed on the display 4 indicates that the site margin is “wide”, “slightly narrow”, or “narrow and problematic”. The three types of display and the corresponding selection buttons may be set as areas, and the corresponding selection buttons may be clicked using the mouse 3 to input numerical values corresponding thereto.

After confirming whether or not all of the above specific information has been input in step S3, in step S4, the total spare days Drt is calculated. The calculation of the total spare days Drt is performed as follows.

(Step S4) That is, firstly, the required actual working days Di for each individual construction are obtained, then the total required actual working days Dt required for building construction are obtained, and the desired completion date input in step S2 is obtained. By subtracting the total required actual working days Dt from the desired total construction period Dwt, which is the difference between the scheduled start date and the scheduled start date, the overall spare days Drt is obtained. Specifically,
By performing the calculations according to the equations (1) to (3), the total spare days Drt is obtained.

Di = Ni / (Mi × Si) (1) Dt = D1 + D2 +... + Dn-1 + Dn (2) Drt = Dwt−Dt (3) where subscripts i = 1 to n (n is various individual Total number of works)
And corresponds to various individual construction events. Also, N
i is the number of works to be constructed by each individual construction (unit: m ² ), Mi is the number of workers to be put in by each individual construction (unit is person), S
i is standard attendance data (unit: person / hour / m ² ) for each individual construction.

In addition, when counting in the above equation (2), the required actual working days of a specific individual construction are calculated by taking into account the process order rules stored in the first storage means 11 among the various types of individual constructions. It is now excluded from counting. That is, in the above-mentioned process order rule, when there is a combination of a plurality of individual works that can be executed simultaneously, only the value of the maximum required actual work days among the required actual work days of the plurality of individual works is the above (2). Used in the tally in the formula, other required working days values are excluded from the tally. In other words, it is possible to obtain a truly necessary or minimum number of days as the total required actual working days Dt.

The calculation of (1) is performed in the step S
As described in the case of inputting the number of workers to be put in 2 and the number of construction objects, automatic table calculation may be used.

(Step S5) Next, in step S5, a concrete construction delay risk is determined for each individual construction in consideration of the actual site situation and the weather fluctuation situation. This concrete construction delay risk is determined as follows.

That is, from the weather statistics data stored in the first storage means 11, the construction site (city) and construction date (for example, the mid-construction period calculated from the scheduled construction start date) of the concrete building input in step S2 Of the third construction delay danger R3 due to weather fluctuations of the concrete building.
Set as For example, if the construction site is Osaka and the month to which the construction date belongs is March, the probability of rainfall with a rainfall of 10 mm or more in March in Osaka from "0.1
3 "is set as the third construction delay risk R3. Then, multiply each of the site margin risk and the front road risk among the first construction delay risks for each individual construction stored in the first storage means 11 by the second construction delay risk, The probability of rainfall in the first construction delay risk is multiplied by the third construction delay risk, and the remaining construction delay risk of the first construction delay risk is divided into three levels regarding the importance of the individual construction. Set importance condition R
4i (“0”, “1”, “2”), and the values after these multiplications are totaled as a concrete construction delay risk.

Specifically, the first construction delay risk R1-ij
(I is the same as the above and is a suffix representing various individual construction items, i = 1 to n; j is a suffix representing each delay element item, and j = 1 to 4). i1 (R1-
i1 = 0-2), site margin risk is calculated as R1-i2 (R1-i2 = 0)
~ 2), the risk of the front road is R1-i3 (R1-i3 = 0-2),
The risk of rainfall impact is R1-i4 (R1-i4 = 0-2), and the second
The site margin condition within the construction delay risk R2-im (m is a subscript representing the site environment item, m = 1 to 2) is defined as R2-i1 (R
2-i1 = 0-2), and the front road condition is set to R2-i2 (R2-i2 = 0-
2) Assuming that the third construction delay risk is R3, the concrete construction delay risk for a certain individual construction is calculated by the following equation (4).

Ri = R1-i1 × R4i + R1-i2 × R2-i1 + R1-i3 × R2-i2 + R1-i4 × R3 (4) For example, a concrete toilet installation work is taken as an example of individual work. In the case of calculating the concrete construction risk danger Ri of the building, the first construction delay danger R1-ij for this temporary toilet construction is referred to as a process delay risk R1-ij.
i1 = 0, site margin risk R1-i2 = 1, front road risk R1-i3 = 1, rainfall impact risk R1-i4 = 1 are pre-evaluated and stored in the first storage means 11, and the concrete building While the site margin condition R2-i1 = 0 and the front road condition R2-i2 = 0 are input and stored in the second storage means 12 as the second construction delay risk R2-im based on the site environment of the object, In step S5, the third construction delay risk R3 based on the rainfall probability is R3 =
0.13 is taken out from the weather statistics data in the first storage means 11, and these numerical values are substituted into the above-mentioned equation (4) as follows. It is assumed that R4 = 2 is input and set as the importance condition.

Temporary toilet construction risk of construction delay = 0
× 2 + 1 × 0 + 1 × 0 + 1 × 0.13 = 0.13 In the above equation (4), “2” is stored and set in advance as the risk of occurrence of a delay is high for an individual work as the first work delay risk. However, if the site environment of the concrete building has a high margin for each delay element, that is, if it is not affected, the second construction delay risk is “0”.
Is set as an input, and as a result of the multiplication as described above, the risk of occurrence of delay for the delay element is eliminated.

(Step S6) Next, in step S6, the assumed individual construction period Dpi for each individual construction is determined based on the specific construction delay risk Ri for each individual construction obtained in step S5.

The basic method is to allocate the total spare days Drt obtained in the above step S4 to various individual works according to the value of the concrete construction risk danger Ri obtained in the above step S5 by substantially proportional distribution. By adding the obtained individual spare days Dri to the required actual working days Di for each individual construction obtained in step S4, the assumed individual construction period Dpi for each individual construction is determined. Here, it is practically preferable to allocate the total spare days Drt in units of one day.

An example of a simplified allocation method may be performed as follows. That is, first, the specific construction delay risk Ri for each individual construction obtained in step S5 is rearranged in ascending order of magnitude, and the range from the maximum value to the minimum value is reduced to some (for example, three ranges). To) Next, for the individual works belonging to the upper first range, the number of days equivalent to, for example, about 50% of the total spare days Drt is set to, for example, about 30% for the individual works belonging to the second range.
The number of days per minute is approximately 20% for individual works belonging to the third range.
Allocate minutes for each minute. Then, the number of days (the minimum unit is one day) obtained by dividing the allocated days by the number of individual works belonging to each range may be allocated as individual spare days Dri to each individual work belonging to the range. In this case, if the calculation result for the allocation is less than one day, the number of days to be allocated may be set to “0”, and that portion may be allocated to individual works with a higher risk of concrete work delay.

Further, when the total number of spare days Drt is relatively short (for example, 10 days), only the individual works belonging to the top 10 out of those sorted in descending order of the above-mentioned values are converted into Dri. What is necessary is just to allocate uniformly one day at a time.

(Step S 7) Based on the assumed individual work period Dpi obtained in the above step S 6, a whole process chart of a bar chart type is created in step S 7 and displayed on the display 4. That is, as shown in FIG. 4, the horizontal axis is the construction date column 21, and the actual construction dates are arranged in order from left to right in the order of progress, as shown in the process chart image 20 created in step S 7 and displayed on the display 4. With the axis as the work name column 22, the individual construction items are arranged from top to bottom in the order of priority execution based on the process order rule, a rectangular coordinate area is set, a process chart is displayed, and each individual work and each construction date in the process chart are displayed. The bar-like symbols (bars) 23, 23, 23, 23, 23, 23
... is displayed.

More specifically, the individual works of the sub-category are displayed in the work name column 22, and in addition, the subcontracting work in charge of the individual work is displayed in the contractor column 24 to the right of the work name column 22. The name of the contractor (the one selected in step S2), the estimated individual construction period Dri of each individual construction in the number of days column 25 on the right thereof, and the above-mentioned individual individual construction period Dri in the start date and end date columns 26 on the right thereof. The actual construction start date and end date based on the construction period Dri are displayed. In the bar chart display column 27, of the bars 23, 23,..., The required actual working days portion 23a is filled with, for example, a specific color (for example, black) by the specific margin days Dri added in step S6. Are displayed in a different form (for example, light blue or dark shaded) from the required actual working days section 23a, while the holiday display 28 of the work suspension day (Sunday) is Are displayed in different manners (eg, gray or light shaded).

In FIG. 4, for example, four individual works of “signboard, temporary enclosure installation”, “temporary toilet installation”, “temporary electric installation” and “temporary water supply installation” of the individual works are performed on February 23.
The two individual works, "Soil treatment" and "Basic work (land leveling-base concrete placement)", were simultaneously carried out from February 24, and the latter work was carried out on February 2.
It shows that it will take place until the 6th. Each bar 23 of each of these individual works is required to be painted.
These are indicated by "a", and indicate that no spare days have been allocated, that is, there is no risk of occurrence of delay. On the other hand, the bar 14 of the 14th "building method / base panel construction" from the top has a required number of working days 23a for three days starting from March 9 and a marginal day part 23b for one day on March 8. In addition, each bar 23 of the 23rd and 24th "system bus construction" and "roofing construction (natural)" construction from the top includes a spare days part 23b for two days on March 16 and 17. , Which indicates that there are extra days for each.

The process chart created in step S7 is not limited to the bar chart type one, but may be a network type one.

(Step S8) Then, the display 4
When the operator wants to change the increase / decrease of the spare days of a specific individual work by examining the process chart image 20 displayed in the above, the cursor is positioned on the spare days section 23b and clicked with the mouse 3 By clicking on the margin date change button 31 set in the upper area of the process chart image 20 with the mouse 3 in a state where the display is highlighted, the increase or decrease is not illustrated. Is superimposed on the process chart image 20 and displayed. The number of extra days is changed based on this image, thereby obtaining step S7.
Then, the process chart is re-created, and the re-created process chart is displayed on the display 4.

(Step S9) If the process chart image 20 displayed on the display 4 in step S8 is not inconvenient,
Various management sheets are created based on the overall process chart. In other words, the material order delivery plan sheet, various arrangement planning sheets, various progress management sheets, frame work schedule sheets, subordinate contractor work schedule sheets for each subcontractor, Create various management sheets such as process sheet sheets for customers.

For example, the material order delivery planning sheet is shown in FIG.
Display 4 as material order delivery plan image 41 shown in
Will be displayed. This is the overall process chart (process chart image 2)
The order date and delivery date are calculated by calculating the number of days necessary for ordering and delivering the material input in step S2 from the start date of various individual works in step 0), and the order date, delivery date, and shipping source are calculated. These are displayed in order of various individual works and from the youngest one on the order date. The arrangement plan sheet is displayed on the display 4 as an arrangement plan image 42 shown in FIG. The arrangement date is calculated from the start date for each individual construction work in the overall process chart as described above by calculating the number of days required for the arrangement entered in step S2, and the date of the arrangement date is calculated for each individual. This is displayed together with the arrangement items required for construction, the arrangement source and the arrangement destination. Further, the various types of progress management sheets collect various types of tasks (tasks) to be performed in the course of the construction, based on the various types of input data and calculation results, as progress management sheets. As an example, FIG. 7 shows each day (e.g., February 2
The task list image 43 for each person on which the task list sheet for each person in charge of the task to be performed on the 7th) is displayed. In the task list image 43, a “material to be ordered today” column 44, a “today's delivery site on-site delivery member” column 45, a “today's arrangement date various arrangements” column 46, and a “today is a work day construction” Column 47, a "construction starting within three days from today" column 48, and an "uncompleted construction within three days from today" column 49 are displayed. For example, the above-mentioned "material to be ordered today" column 44 indicates the order date and delivery date of the material ("fireproof eaves sky board" and "non-combustible decorative body difference" are displayed in FIG. 7). This is an order date and indicates to the operator that it is necessary to place the order.

(Step S10) Finally, by clicking with the mouse 3 the print button 32 set in the upper area of each of the images 20, 41, 42, and 43, a print command for the printer 5 is output. Images 20, 4
1, 42 and 43 are printed.

By the above process, a process chart is obtained, and process management is performed based on the process chart. Also,
In the case where an unexpected situation occurs during the construction to cause a discrepancy with the above process schedule (when a delay occurs), in the process schedule image 20, the allowance date of the individual construction work after the occurrence of the above situation is described. As described in the processing in step S8 above, by reducing and recalculating, a process chart is created and displayed in which the number of spare days is redistributed so that all building construction is completed by the desired completion date. Can be.

In the flowchart of FIG. 3, the first step is performed by steps S1 to S3, and the second step or the first processing means 14 is performed by step S4.
However, step S5 constitutes the third step or second processing means 15, step S6 constitutes the fourth step or third processing means 16, and step S7 to step S10 constitutes the fifth step or fourth processing means 17. .
