The present invention has the following advantages and beneficial effects:

1) this method has wide applicability.Due to the difference between industry, even each producer inside of the same trade Production technology is also not quite similar, the executive plan generation method or applicability is narrow or enforceability is low that regular software provides. This method is modeled according to different productive prospecting piecemeals, so that this method has extensive industrial applicability.

2) accuracy of this method and adjustability are very high.Process provides the flexibilities that two parameters are used to control plan With the real-time of production status.Once Plan rescheduling, this method can generate new executive plan quickly, so that planning to have very high Feasibility and accuracy.It can guarantee that system really reflects entire process flow with machine state state modulator production status Production status.

Detailed description of the invention

Fig. 1 is executive plan product process figure.

Specific embodiment

The present invention is described in further detail with reference to the accompanying drawings and embodiments.

According to industry characteristic, entire technique is split as several associated sub- process modelings, this little process modeling It can be flexible manufacturing model by naturalization.The present invention has gone out a set of calculate based on Giffler& according to flexible manufacturing model development The operation method of Thompson algorithm.

[basic conception]

Assign plans: according to production task demand, manufacturer can produce by certain type product is assigned in month or week The production plan of quantity out.

Executive plan: for assigning plans, factory will formulate process time and the processing sequence of each workpiece, every machine The workpieces processing time and sequence.

Process: the order of entire production process Zhong Ge workshop section converted products.

Technique: the entire production process of certain type product is processed.

One, it is illustrated first to according to process characteristic modeling.

1, under normal conditions, if the production of a product can pass through arterial highway production process, process be single machine, have Process be pipeline system production.The processing method of heat treatment etc. is also different with the mode of common process.The raw material of certain processes Batch size is also different with other processes.So the first step of modeling is according to production method, processing method, reproduced goods processing side The process of close technology mode is classified as a production module by the sequencing of process by the features such as formula, batch.It is our in this way The technique of one product is abstracted as several production modules by method；

2, virtual link pond is established, the operation result that module is produced according to upper one is generated to the finished product of the module in pond Information, including material are processed on which platform machine, beginning process time on this machine.System built-in algorithm by the information from Turn changes the input raw material information of next module into, and the finished product information of last production module is the defeated of next production module Enter raw material information.
