Abstract

The invention discloses a workshop scheduling optimization method, device and workshop equipment layout. Aiming at the problem of one worker operating multiple machines considering the human-machine interference phenomenon, a multi-objective optimization mathematical model is established to solve the processing sequence of different workpieces to achieve the minimum Optimize machine idle rate and worker walking path goals. An improved longest processing time first (ILPT) algorithm and a non-dominated sorting genetic algorithm with elitist strategy (NSGA‑II) are proposed to solve this problem. Compared with the rules actually applied, both NSGA‑II and ILPT can reduce the machine Idle rates and reduced worker walking paths. The NSGA‑II algorithm can obtain multiple Pareto optimal solutions, and is suitable for scenarios that have higher requirements for effects or require multiple solutions; ILPT is suitable for scenarios that require high machine utilization and high real-time requirements.

Description

technical field [0001] The disclosure belongs to the technical field of processing and manufacturing automation, and relates to a workshop scheduling optimization method, device and workshop equipment layout. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] At present, the transformation and upgrading of domestic manufacturing enterprises, especially in some labor-intensive industries, the automation, mechanization, and informatization transformation of enterprises have gradually become the focus of managers' consideration. In order to improve production efficiency and processing quality, many processing and manufacturing industries have introduced advanced equipment and technology. Among these, some types of equipment can work for a long time with only a short manual operation, and do not require worker guards. The manager usually arrang...
