Abstract

The invention provides a distributed flexible workshop scheduling method and system with a transportation process, and the method comprises the steps: obtaining the information of a to-be-processed workpiece, and the related information of a distributed flexible workshop; obtaining a scheduling result according to the to-be-processed workpiece information, the distributed flexible workshop related information and a preset distributed flexible workshop scheduling model; wherein the distributed flexible workshop scheduling model is set to be a sequence-based mixed integer linear programming model for simultaneously optimizing the completion time and the total energy consumption by using a weighted sum method; when the transportation time between the machine tools is determined, a virtual machine tool is preset, and the process of conveying each workpiece by the virtual machine tool is set as a first process; according to the method, the typical constraint condition of transportation time between machine tools is considered, the completion time and the total energy consumption in the multi-objective problem are optimized at the same time by using a weighted sum method, and a sequence-based MILP mathematical model is established for the first time.

Description

technical field [0001] The invention belongs to the technical field of workshop scheduling, and in particular relates to a distributed flexible workshop scheduling method and system with transportation process. Background technique [0002] In recent years, with the increasing popularity of collaborative production among enterprises, distributed manufacturing systems have received extensive attention; due to the important theoretical and application value of distributed scheduling problems, it has been extended to distributed parallel machine scheduling problems, distributed replacement Distributed Flexible Job-shop Scheduling Problem (DFJSP) is a typical branch of Distributed Job-shop Scheduling Problem (DSSP), which has Multiple factories work at the same time, and each factory represents the characteristics of a flexible job shop. The DFJSP problem contains three-dimensional optimization problems, including workpiece allocation problems, machine tool allocation problems a...
