Embodiment Construction

[0060] The basic idea of ​​the present invention is to use the biological behavior-based data model to model the production-related data of the job shop, and calculate the dynamic scheduling parameters; after that, the biological behavior-based data model that carries the dynamic scheduling parameters can be directly used in turn. Generate scheduling instructions, and recalculate dynamic scheduling parameters when disturbance information is received, so as to speed up the response to disturbance information and achieve the purpose of real-time scheduling.

[0061] figure 1 It is a flowchart of Embodiment 1 of a method for realizing real-time scheduling of a job shop in an embodiment of the present invention. Such as figure 1 As shown, this embodiment includes:

[0062] Step 101: Establish the production-related data of the job shop as a data model based on biological behavior.

[0063] In this step, the biological behavior-based data model is mainly a data model established by ...

Abstract

The invention provides a method and a system for realizing the real-time scheduling of a job shop. The method for realizing the real-time scheduling of the job shop comprises the following steps: A, establishing a data model based on biological behaviors according to input related production data of the job shop; B, utilizing the related production data of the job shop to calculating a dynamic scheduling parameter of the data model based on the biological behaviors; C, generating a scheduling command according to the data model which is based on the biological behaviors and carries the dynamic scheduling parameter, sending the generated scheduling command to a job shop subsystem and recalculating the dynamic scheduling parameter by disturbance information when the disturbance information from the job shop subsystem is received; and repeatedly carrying out the step C till the scheduling of the job shop is completed. Because only the dynamic scheduling parameter is calculated during disturbance, the reaction speed of the system to disturbance situation is increased, the requirement of the real-time scheduling is met and the production efficiency of enterprises is improved.

Description

Technical field [0001] The invention relates to automation technology, in particular to a method and system for realizing real-time scheduling of job shops. Background technique [0002] With the continuous development of enterprise automation technology, the goal of optimizing management of the entire production process from product order placement to product completion is currently proposed, that is, to achieve the Manufacturing Execution System (MES). In the manufacturing execution system, in order to improve production efficiency, reduce production costs and other factors, it is necessary to control the processing process of the job shop, that is, to realize the real-time scheduling of the job shop. [0003] Real-time scheduling of job shops is a very complex problem. Taking discrete processing as an example, suppose that the job shop includes m equipments, and a complete product can be completed through n processes; one equipment has one or more functions, and a certain func...
