Abstract: A general description of multi-line manufacturing systems with alternative coupled machines was given and designed to study performance optimization problems of the multi-line manufacturing systems on the basis of classic MiniFAB model. A feedback structure optimization method was proposed to solve the problems of insufficient training data when optimizing a multi-line manufacturing system. Structure optimization method was further collaborated with selection of heuristic rules to improve accuracy of performance optimization. As a result, the collaborative optimization method for multi-line manufacturing systems was proposed. Feasibility and effectiveness of the proposed methods were verified through cases.

Key words: multi-line manufacturing system, closed-loop optimization, heuristic scheduling rule, collaborative optimization

摘要: 为研究具有可互替耦合设备的多生产制造系统的优化问题,给出了该类型制造系统的一般性描述,并基于经典的MiniFAB模型设计了该多生产线制造系统。为解决优化过程中训练数据不足的问题,提出了基于反馈机制的多生产线制造系统结构优化方法。为进一步提高优化方法的精度,将结构优化方法与启发式调度规则优化结合,提出了多生产线制造系统协同优化方法。案例验证了所提出方法的可行性和有效性。
