Embodiment Construction

[0029] The method of the present invention is illustrated by taking a pharmaceutical production workshop as an example in conjunction with the accompanying drawings.

[0030] figure 1 Describes the specific modules of each step of the dispatching method and the diagram of the relationship with the upper layer ERP, SCM, DCM and the lower layer production process monitoring. First, collect the basic attributes and constraints of a drug and its raw materials, production equipment, storage devices, etc., as well as the sales plan, raw material procurement plan and equipment maintenance plan of the drug, establish the basic data of the production scheduling system, and carry out the production process of the drug. Visual modeling, you can choose production process flow chart description modeling or production process relational modeling; then according to the sales plan of the drug, raw material procurement plan, equipment maintenance plan, intermediate and raw material inventory i...

Abstract

The invention includes description and modeling of manufacturing technique flow, optimized model solving, and simulation of production process, dynamic monitoring and readjusting production process. Description and modeling of manufacturing technique flow describes technique flow, and builds model of optimizing scheduling system. Optimized model solving includes data file creation of object model and model file creation, automatic solving, and displaying optimized scheduling scheme of production. The invention builds visual integral intelligent frame, and implements simulated optimizing scheduling in production flow through functions supplied by the invention.

Description

technical field [0001] The invention belongs to the technical field of automation, and relates to a method for a simulation optimization dispatching system in the process industry. Background technique [0002] Foreign countries attach great importance to the production scheduling of process industries. At present, foreign scheduling software has been widely used in petrochemical, pharmaceutical, manufacturing and other process industries. Foreign research on production scheduling problems focuses on optimal scheduling based on mathematical programming models, with emphasis on quantitative scheduling; domestically, considering factors such as management and measurement, focuses on heuristic scheduling methods based on artificial intelligence, and focuses on qualitative scheduling. Although some progress has been made in the production scheduling model, algorithm and computing performance in China, the actual scheduling problem is far from being solved. The production plannin...
