For example, there are currently five pieces of wiring poles fixed in XX city △△△ chome. Stock information and position information are associated with each other such that optical fibers are installed, of which two are in use and three are not in use.

  Returning to FIG. 1, the inventory management device 1 manages the inventory of the optical wiring equipment necessary for the optical service provided using the optical line, and provides the delivery date necessary for starting the optical service. Specifically, a construction form information storage unit 10 that stores inventory information and construction forms in association with each other, a delivery date information storage unit 11 that stores construction forms and periods necessary for construction in association with each other, The facility construction information storage unit 12 that stores the optical wiring facility inventory information and the position information in association with each other at the timing, the reception unit 13 that receives a request for delivery of the optical service, and the optical wiring facility inventory information at the predetermined timing It is the structure provided with the construction form specific | specification part 14 which specifies a construction form based on position information, and the delivery date information generation part 15 which makes a period corresponding to the specified construction form a delivery date. Hereinafter, each information stored in the construction form information storage unit 10 and the delivery date information storage unit 11 will be described more specifically.

  In the construction form information storage unit 10, inventory information indicating the stock status of the optical wiring equipment and construction forms necessary for providing the optical service corresponding to the inventory information are stored in association with each other. The inventory information is managed as inventory information corresponding to the number of off-site splitters, optical cores, and tapes constituting the optical wiring facility. Before explaining the details of the inventory information, the positional relationship between the fixed equipment and the optical wiring equipment installed between the FTM (Fiber Termination Module) accommodated in the accommodation station that provides the optical service and the user's home will be explained. . Note that FTM means a module that terminates a plurality of subscriber optical cables.

  FIG. 3 is a diagram illustrating an example of an installation state of the optical wiring facility. The FTM 51 accommodated in the accommodation station 50 is terminated with 11 tapes 53 for bundling the three optical cores 52. The optical fiber 52 is laid from the accommodation station 50 to the user's home 54 via a plurality of fixed facilities in the underground area A and the imaginary area B. The tape 53 is not originally a bundle of optical cores 52 but is a bundle of optical cables as described above, but the unit of quantity of the optical cores and the optical cables is often the same. Therefore, here, the description will be continued with the optical fiber 52 unified.

  A point where the optical fiber 52 is pulled up from the underground area A to the imaginary area B is referred to as a “line point”, and this “line point” is provided for each range of about 400 to 600 user houses. The section from the “cutting point” to the user's home is referred to as a fixed wiring section, and the optical core 52 is connected to each of a range of about 50 user homes via a plurality of wiring columns 55a to 55d existing in the fixed wiring section. The wiring pillar 55e is installed as a “wiring point” located in the wiring block partitioned by (1). And it becomes possible to provide an optical service by drawing the lead-in wire 57 extended from the off-site splitter 56 connected to the optical fiber 52 installed in the wiring pillar 55e into the user's home 54. Of course, depending on the wiring block, the wiring pillar 55a located at the “wiring point” may become the wiring pillar 55e located at the “wiring point”.

  The inventory information will be described based on the content described with reference to FIG. FIG. 4 is a table showing an example of inventory information and a construction form stored in the construction form information storage unit 10. This inventory information includes the off-site splitter inventory that indicates the number of empty terminals of the off-site splitter, the wiring point inventory that indicates the number of empty cores that have been separated from each other at the wiring point, and the number of cores that can be provided immediately at the wiring point The number of cores in stock indicates the number of empty cores in the overhead route from the “trailing point” to the wiring point in the fixed wiring section. It is divided into a line dotted line tape inventory indicating the number of tapes, a line dotted underground tape inventory or an underground route tape inventory indicating the number of empty tapes in the underground area. Each piece of inventory information is associated with various construction forms necessary for providing the optical service.

  Note that the inventory information shown in FIG. 4 is classified according to the inventory associated with the positions such as the wiring points and the “line points”. Since there is a plurality of inventory information corresponding to each of the outer splitter, tape, etc., the same information can be obtained by dividing the inventory information using only the inventory information indicating the status of the inventory of the optical wiring equipment regardless of the position. An effect can be obtained.

  The delivery date information storage unit 11 stores a plurality of construction forms and respective periods necessary for the construction of the plurality of construction forms in association with each other. FIG. 5 is a table showing an example of the relationship between the construction form and the period stored in the delivery date information generation unit 15. For example, the construction period required for the construction form of construction PT (pattern) 1 is 1 day, and the construction period for construction PT4 is 7 days. These are associated using units such as. FIGS. 6A to 6C are diagrams illustrating examples of specific construction contents in a plurality of construction forms. Referring to FIGS. 5 and 6-1 to 6-3, for example, in the case of the construction form of construction PT 2, the contents of construction that are actually required are drop installation, SP (splitter) installation, and AO ( Wiring box) It is newly established, and it is possible to grasp that the period required for the construction is 2 days.

  The received construction information indicates inventory information indicating the status of the stock of the optical wiring equipment, position information indicating the position where the optical wiring equipment is installed, and blocks partitioned by a predetermined number of buildings that provide optical services. More specifically, the wiring block information is the same information as the information described with reference to FIG. These inventory information, position information, and wiring block information are stored in the facility construction information storage unit 12 in association with each other. The construction information registered in the construction information storage unit 3 may be reflected at night by batch processing after the completion of the construction of the optical wiring equipment for the fixed equipment.

  Next, the reception unit 13 of the inventory management apparatus 1 receives a request for a delivery date necessary for providing the optical service for a predetermined position from the reception terminal 4 installed in the reception center 400 (step S2).

  This predetermined position is a telephone number of a fixed telephone at the user's house or an address of the user's house, and is a position where the place where the optical service is provided can be grasped. Further, it may be a wiring pillar installed closest to the user's house, and if it can be grasped by the reception center 400, it is the location of the wiring pillar as a wiring point located in the wiring block including the user's house. May be.

  Subsequently, the construction form specifying unit 14 reads the inventory information corresponding to the position information indicating the position of the optical wiring facility installed at the requested predetermined position from the facility construction information storage unit 12, and uses the read inventory information. A corresponding construction form is specified from the construction form information storage unit 10 (step S3).

First, the construction form specifying unit 14 searches the wiring block information stored in the facility construction information storage unit 12 for the wiring block corresponding to the predetermined position received in step S2 (step S3-1).

  Then, the stock status of the wiring equipment existing between the wiring pillar installed in the searched wiring block and the accommodation station, the optical fiber information stored in the equipment construction information storage unit 12 and the outside splitter information The current inventory status for the received predetermined position is grasped (step S3-2).

  Here, when grasping the current stock status, it will be described which stock described in each piece of information shown in FIG. 2 is used to obtain each stock of the stock information shown in FIG. The stock status for the off-site splitter stock is obtained based on the optical equipment information, the wiring block information, the off-site splitter information, and the off-site splitter terminal information. Then, the stock status for all stocks other than the off-site splitter stock is obtained based on the optical equipment information, the optical fiber information, and the wiring block information.

  Finally, the construction form specifying unit 14 specifies the construction form corresponding to the grasped inventory status from the construction form information storage unit 10 (step S3-3).

  For example, when there is an off-site splitter stock, that is, when there is an empty terminal at the off-site splitter installed at the predetermined position, the construction is performed based on the construction form information stored in the construction form information storage unit 10. The construction form of PT1 or construction PT3 is specified. If there is no vacant terminal, next, the construction form is specified according to the status of the stock of the optical wiring equipment installed at the predetermined position so as to confirm the presence or absence of the ready stock.

  Thereafter, the delivery date information generation unit 15 reads a period corresponding to the specified construction form from the delivery date information storage unit 11, and sets the read period as a delivery date necessary for providing a service for the requested predetermined position (step S4).

  Finally, the inventory management apparatus 1 transmits the delivery date to the reception terminal 4 (step S5). Note that it is also possible to omit steps S2 and S5 and store a plurality of delivery dates specifying all construction forms for all wiring blocks in a storage unit (not shown).

  FIG. 8 is a flowchart showing an example of the flow of processing until the conventional HIKARI service is provided to the user. As shown in the figure, when the application for the optical service is received from the user, the reception center inquires the inventory management delivery date information center about the examination of the optical wiring equipment, and after the equipment design is completed, Since it is necessary to answer, a plurality of reception times are generated for the user, and the start date of the HIKARI service cannot be provided promptly.

  FIG. 9 is a flowchart illustrating an example of a flow of processing up to provision of a HIKARI service to a user using the inventory management apparatus described in the present embodiment. As shown in the figure, at the time of the primary reception when the application for the optical service is made by the user, the reception center makes an inquiry about the information on the delivery date to the inventory management device installed in the inventory management delivery date information center. It becomes possible to quickly determine the delivery date required for the construction. Furthermore, it is possible to quickly determine the construction start date with the user.

  The processing of the inventory management apparatus 1 described in the present embodiment is recorded as a program on a recording medium such as a compact disk or a floppy (registered trademark) disk, and this recording medium is incorporated into a computer or recorded. By downloading a program recorded on a medium to a computer via a communication line or installing the program from a recording medium and operating the computer with the program, the above-described processing can be functioned as the inventory management apparatus 1.
