摘要
针对柴油机制造企业产品结构复杂、加工制造周期长、设备利用率低以及生产过程中人为调度密集,底层信息不能及时反馈等现状,提出了面向柴油机制造企业基于MES的车间单元调度系统。首先分析了系统的体系结构,调度流程以及实现功能,在此基础上建立了车间单元调度的多目标模型,并进一步采用基于TOC的遗传-分散搜索混合算法进行求解,使车间单元调度系统更具科学性和实用性。
According to the diesel engine products with complicated structure,long processing cycle,low utilization rate of equipment,intensive artificial scheduling and the underlying information without feedback,the diesel engine manufactory workshop scheduling system based on MES is proposed.Firstly, this paper analyzes the structure of the system,the scheduling process and functions.On this basis,we established a multi-objective model to the workshop scheduling,and further we used genetic-scatter search algorithm based on TOC to solve the problem,which makes the workshop scheduling system more scientifically and practically.
