Embodiment Construction

[0023] Such as figure 1 As shown, the system adopted in the present invention includes a basic data maintenance module, a data acquisition module, a production process description module, and a model generation module. For the case of ERP or other information systems, the data collection module completes data collection from the sales subsystem, procurement subsystem, inventory subsystem, and equipment subsystem, including sales plans, purchase plans, inventory information, equipment maintenance plans (or equipment failure information), otherwise such data can be input manually and stored in the database server.

[0024] Basic data maintenance completed: establish and maintain basic information of production devices (equipment), storage devices, raw materials, intermediates, and products, and provide basic data for production system modeling.

[0025] The production process description module mainly provides a visual description of the production process of the production sys...

Abstract

The invention discloses effective description based on visible production system in the advanced manufacture and automatic technique domain, which is characterized by the following: basic data maintenance establishes and maintains basic information of production device or equipment to provide basic data for production system modeling; data collection collects the needed data for modeling according to the dispatching time scale; production technique description provides production technique flow visible description for production system; model generation forms production system resource data text file of model base requirement according to the input optimum dispatching parameter of user. The invention can dispose wide dispatching problem in the production course.

Description

technical field [0001] The invention belongs to the technical field of advanced manufacturing and automation, and relates to a visual description modeling method of a process industry production optimization scheduling system. Background technique [0002] The process industry production system has the characteristics of multi-variety, large batch, short cycle, complex operation (including equipment failure, maintenance, material-intermediate product-product association, etc.), and contains a large number of complex resource constraints, process constraints and energy constraints. The real-time and coordination requirements of production scheduling are very high. The modeling, scheduling, and verification of the production optimization scheduling system are very complicated and have extremely high requirements for users. It is very difficult to establish an effective optimal scheduling system. [0003] At present, the level of production planning and dynamic scheduling in t...
