Abstract

The invention discloses a flowshop multi-target scheduling optimization method, solves the problems that an existing built flowshop multi-target production scheduling model is poor in reacting ability, and can change and adjust the production scheduling strategy at will according to the company production needs; the method comprises the following steps: facing at the flowshop, and building a workshop production operating time, production cost and workshop energy consumption multi-target mathematics model; using a normalizing weight method to optimize the workshop production scheduling; using a hierarchy analytical method to decide each index weight according to company needs, and using a heredity algorithm to carry out searching optimization iteration so as to obtain the scheduling optimization scheme.

Description

technical field [0001] The invention relates to the technical field of workshop scheduling, in particular to a multi-objective scheduling optimization method for flow workshops. Background technique [0002] The flow shop scheduling problem can usually be described as: a batch of workpieces to be processed are processed through a specific processing system in a certain order. The processing procedures of each workpiece are the same, and each machine tool corresponds to a procedure. At the same time, by scheduling the processing sequence of workpieces and rationally allocating system resources, some indicators are optimized. Flow shop scheduling, as a typical production operation mode, has been widely used in discrete manufacturing, so it is of great theoretical and engineering application value to study the flow shop scheduling problem. [0003] At present, a large number of scholars have established corresponding production models from different production perspectives to ...
