Dynamic production scheduling method and system of flexible machining production line and application of G-series high-speed train part group flexible-machining production line

Abstract

The invention discloses a dynamic production scheduling method and system of a flexible machining production line and application of a G-series high-speed train part group flexible-machining production line, belongs to the fields of complicated production, information technologies and advanced manufacturing and aims to solve the scheduling problem of initial production scheduling plan deviations caused by random production of interference events in a machining environment of the flexible machining production line. The technical characteristic is that a mixed particle swarm optimization algorithm including multi-layer neighborhood search structures of a Gaussian mutation operator and / or randomized policy is used in the dynamic production scheduling process of the flexible machining production line to obtain a re-scheduling scheme. The dynamic production scheduling method and system have the advantages that an initial scheduling plan is dynamically corrected according to random disturbance information to respond to random disturbance.

Description

technical field [0001] The invention belongs to the fields of complex production, information technology and advanced manufacturing, and relates to a dynamic production scheduling method of a flexible machining production line. Background technique [0002] At present, my country's complex equipment manufacturing industry is developing rapidly, and at the same time, it is also facing many problems in the process of parts manufacturing. The manufacturing of parts for high-speed rail EMUs is a typical representative of this phenomenon. The following characteristics: the same process is jointly undertaken by parallel machines, and there is machine flexibility; the number of machines, parts, and processes is large; the delivery time of parts is strict, and the cost of parts delay is high; due to machine maintenance, machine failure, etc. The disturbance of the machine causes the processing of parts to be blocked and affects the delivery date; the processing of parts is blocked and...
