Reconfigurable manufacturing system polymorphic configuration optimization method based on tasks

Abstract

The invention discloses a reconfigurable manufacturing system polymorphic configuration optimization method based on tasks. The reconfigurable manufacturing system polymorphic configuration optimization method comprises the following steps that firstly, according to changes in market requirements, feature information of the dynamic tasks is obtained, process features of a part to be machined are analyzed, and the priority levels of the tasks are determined; secondly, a dynamic space model used for describing the state change process of the tasks and a machine tool capacity space model used for describing the number of machine tools are established; thirdly, a mapping relation from dynamic task space to machine tool capacity space is established, and reasonable station operation is distributed to the dynamic tasks through the Markov decision process on the basis of the mapping relation; fourthly, a task distribution mechanism which enables the machine tool capacity to be optimized is established according to machining capacity information of the machine tools; fifthly, a system queue model used for describing the task state input and output process is established according to the task distribution mechanism and a system optimization objective, and multi-objective optimization analysis is conducted on the system configuration through epsilon-dominated adaptive particle swarm optimization.

Description

technical field [0001] The invention belongs to the technical field of processing and manufacturing, and relates to an optimization method in the field of manufacturing system configuration, in particular to a task-based multi-state configuration optimization method for a reconfigurable manufacturing system. Background technique [0002] Configuration optimization is an important link for a reconfigurable manufacturing system to respond economically and quickly to diverse market demands. Each life cycle of a reconfigurable manufacturing system has different task requirements in its entire life cycle, and each task requirement requires Different configurations match it. The configuration of the reconfigurable manufacturing system is mainly considered from the following two aspects: device layer configuration and system layer configuration. The equipment layer configuration is mainly to determine the combination and connection relationship between the equipment modular compon...
