Multi-variety batch product mixed routing manufacturing real time state management method

Abstract

The invention provides a multi-variety batch product mixed routing manufacturing real time state management method comprising the following steps: 1, building a part processing procedure attribute model; 2, building a mixed routing manufacturing process dimension state model; 3, building a mixed routing manufacturing resource attribute model; 4, building a mixed routing manufacturing resource dimension state model; 5, building a mixed routing manufacturing real time state model that takes the part processing procedure and the mixed routing manufacturing resource as nodes and takes a task resource association relation as an edge. The method can fast and accurately describe the mixed routing manufacturing specific process from the procedure, resource and manufacturing route dimensions; the whole state model has instantaneity, thus effectively reflecting the production plan execution conditions under the current state, and providing accurate, comprehensive and real time data for real timeoptimization and cooperation management of the mixed routing manufacturing system; the method is simple, and suitable for describing the real time states of the multi-variety small batch product mixed routing manufacturing process.

Description

technical field [0001] The present invention relates to a production system management method in the field of computer integrated manufacturing, in particular to a real-time state management method for multi-variety batch product mixed-line production, especially a description method for multi-variety and small-batch product mixed-line production real-time state management. Background technique [0002] Most aerospace products are multi-variety and small-batch products, and their research and batch production models are produced in a mixed line. This kind of production process has strong dynamic and uncertain characteristics. To achieve effective control of the production process, it must be based on product technology, resources, Multiple dimensions such as production line quickly and accurately describe the specific process of mixed-line production. At present, domestic and foreign scholars have proposed a variety of modeling methods in terms of state modeling of mixed-lin...

Problems solved by technology

Considering that the mixed-line production of multi-variety and small-batch products involves research and batch production models, and manufacturing resources involve materials, personnel, equipment, molds, fixtures, etc., the process of mixed-line production is actually a process of different models, different products and manufacturing resources in time. However, for such a complex mixed-line production system, the existing methods are all real-time state models built on a specific dimension, and there is no multi-dimensional state management method for mixed-line production. Therefore, It is necessary to propose a real-time state model that uses multiple dimensions and interacts with each other to fully describe the mixed-line production process of multi-variety and small-batch products
