Partial reconfiguration method of reconfigurable manufacturing system

Abstract

The invention discloses a partial reconfiguration method of a reconfigurable manufacturing system. The method comprises the following steps of constructing the reconfigurable manufacturing system (RMS) for workpieces of a workpiece family; for the workpiece i, dividing a process route of the workpiece i into a Pi1 part and a Pi2 part; calculating an income Bi of the wrokpiece i; when Bi=0, calculating a value, defined in the specification, of corresponding Oi<sp>, wherein the value is used for dividing the process route of the workpiece i into the Pi1 part and the Pi2 part, namely, reconfiguration points of the workpiece i, and reconfiguration points of the workpieces 1-n are defined in the specification; calculating a total income, defined in the specification, of a D-RMS; under the condition that B>0, selecting a reconfiguration point from the reconfiguration points of the workpieces 1-n as a reconfiguration point O1<sp> of the D-RMS; by utilizing the O1<sp>, dividing the process route of the workpiece i into a P'i1 part and a P'i2 part; by utilizing the P'i1 parts of all the workpieces in the workpiece family, constructing a first subsystem of the DRMS; by utilizing the P'i2 parts of all the workpieces in the workpiece family, constructing a second subsystem of the D-RMS, and adding a storage warehouse of semi-finished products between the two subsystems to construct the D-RMS; and by utilizing the D-RMS, manufacturing the workpieces in the workpiece family.

Description

technical field [0001] The invention relates to the field of advanced manufacturing technology, in particular to a partial reconfiguration method of a reconfigurable manufacturing system. Background technique [0002] The reconfigurable manufacturing system RMS (Reconfigurable Manufacturing System) is a new generation of manufacturing system that combines the advantages of the flexible manufacturing system FMS (Flexible manufacturing system) and the rigid manufacturing system DMS (Dedicated manufacturing system). The changing manufacturing environment has become a research hotspot in the field of manufacturing. RMS aims to provide accurate processing functions and processing capabilities at accurate time for new requirements through reconfiguration. The implementation of RMS includes system design, system construction, production, reconstruction, etc., and reconstruction is the key link to realize the advantages of RMS. [0003] At the beginning of RMS design, the basic st...

Problems solved by technology

However, shutting down the entire system causes production interruptions, resulting in lost capacity

[0006] (2) The reconfiguration goal of RMS is to provide precise processing function and processing capacity, resulting in reconfiguration even between two very similar workpiece configurations, which may lead to a complex reconfiguration process, thereby increasing the reconfiguration Time and Refactoring Costs

[0007] (3) The inventory problem is not involved in the existing RMS reconstruction research
