Summary of the invention

For above shortcomings part in prior art, the present invention provides a kind of based on according to process characteristic modeling the configurable stagewise production task scheduling method that can regulate implement plan according to parameter.

The present invention is the technical scheme is that a kind of configurable stagewise production task scheduling method for achieving the above object, comprises the following steps:

According to factory's actual process flow process, technological process is divided into the some sub-technique being associated, and every sub-technique is implemented in production, formed and produce module;

Each produces sets up virtual connection pool between module, establish the input and output content of connection pool, completes the information transmission of the superior and the subordinate's technique;

Each production module sets up model according to the concrete technological process of its correspondence, the input/output argument of establishing model;

Input, at first line technique place, parameter of assigning plans according to given form, obtain implement plan and each implement plan design parameter value in its technological process;

According to the actual requirements, adjust parameter, optimize implement plan.

Described every sub-technique is used for generating this stage product, in whole technological process goods be interim product and need will the Data Enter of this stage product in information system, then the sub-technique of this stage product of generation being split.

Virtual connection pool is set up between described each sub-technique, particularly as follows:

The operation result that upper one produces module is entered in data base;

Call Giffler&Thompson algorithm and carry out computing record product title, coding, quantity information in connection pool as the finished product information of current block;

The finished product information of current block is converted the input raw material information of next module to: the title of the finished product in connection pool and coding are constant, quantity is divided by batch size, the new finished product information generated exists in other database table, as the input raw material information of next module.

Described every sub-technique sets up model according to concrete technological process, and model comprises following information: process name, the operation comprised under this flow process, the material that this flow process generates, the station corresponding with operation.

The present invention has the following advantages and beneficial effect:

1) the method has wide applicability. Due to the difference between industry, even the production technology of each producer internal of the same trade is also not quite similar, the implement plan that regular software provides generates method or the suitability is narrow, or enforceability is low. This method is according to different productive prospecting piecemeal modelings so that the method has industrial applicability widely.

2) accuracy of the method and adjustability are significantly high. Process provides the real-time of the motility for control plan of two parameters and production status. Once Plan rescheduling, this method can quickly generate new implement plan so that plan has significantly high feasibility and accuracy. Can ensure that system reflects the production status of whole technological process really by machine state state modulator production status.

Detailed description of the invention

Below in conjunction with drawings and Examples, the present invention is described in further detail.

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

[basic conception]

Assign plans: according to production task demand, manufacturer can by the production schedule assigning certain type product output quantity in month or week.

Implement plan: for assigning plans, factory to formulate process time and the processing sequence of each workpiece, processing work time of every machine and order.

Operation: the order of whole production process Zhong Ge workshop section converted products.

Technique: process the whole production process of certain type product.

One, first illustrate according to process characteristic modeling.

1, under normal circumstances, the production of a product can through some roads production process, and some operations are single machines, and some operations are that pipeline system produces. The processing mode of heat treatment etc. is also different with the mode of common process. The raw material batch quantity of some operation is also different with other operations. So the first step of modeling is according to the mode of production, processing mode, reproduced goods processing mode, batch etc. feature, by the sequencing of operation, the operation of close technology mode is classified as one and produces module. This Sample Method produces module by abstract for the technique of a product for several;

2, virtual link pond is set up, by generating the finished product information of this module according to a upper operation result producing module in pond, including material is processed on which platform machine, beginning process time on this machine. This information is automatically converted into the input raw material information of next module by system built-in algorithms, and the finished product information of last production module is the input raw material information of next production module.

3, system provides different implement plan schemes. Difference between scheme is to be determined by the iterations of different algorithms. Iterations is more many, and it is more tight that implement plan is arranged, but operation time is more long. Iterations is less, and computing is more fast, but the implement plan result obtained is likely to many not as iterations. So make client can select to meet according to practical situation the scheme of oneself productive prospecting.

Two, the realization of method can be adjusted after generating implement plan according to parameter

In order to ensure real-time and the adjustability of system, this implement plan generates system and introduces two parameters, and one is the weight parameter assigned plans, and another is the operational factor of production equipment.

The weight parameter assigned plans is divided into Three Estate, and 1 is non-emergent, if it is later for date of delivery to produce order, may be configured as this weight. 2 is common order, and this weight is default value. Being rush order more than 3, the more big then urgency level of numerical value is more high. The typing when raw material information inputs of this parameter. In process of production, if order adjusts, then can adjusting this parameter value, then system regenerates new implement plan for Instructing manufacture. Production efficiency can be improved, in order to avoid equipment is dragged the phase by non-emergent task Occupation time and hot job.

The operational factor of production equipment is used for controlling the operation of everyday devices. If device damage or ordinary maintenance, it is possible to adjust equipment operational factor. So can make a plan accurately according to production status, it is ensured that the accuracy of implement plan and motility.

As it is shown in figure 1, one embodiment of the present of invention is:

1, produce module to set up, by process characteristic difference, whole production procedure is split into several according to produced on-site situation and produce module.

2, information needed is modeled in the typing of Data Enter interface. Include M platform machine as produced modules A, machine m can process part kind e1, e2 ... en} and processing duration t1, t2 ... tn}; The machining set of part n needs and order.

3, system sets up virtual link pond automatically between adjacent production module, includes the finished product information producing module and be automatically converted into the input raw material information of next module in pond;

4, will assign plans and split into raw material information, and typing before first production module;

5, system can record according to built-in algorithm and generate the product information in each connection pool and the finished product information of last production module generation automatically.

6, assign plans according to order adjustment, keep the accuracy of implement plan. State parameter according to equipment adjusts equipment state, it is ensured that the real-time of the production process of system reflection.
