基于敏捷制造单元的车间动态重构

为适应现代车间的敏捷化需求,提出了一种基于敏捷制造单元的车间动态重构方法.车间的动态重构是一个优化制造资源,进而构造面向产品的敏捷制造单元,形成虚拟车间的过程,采用数学规划和模糊理论相结合的方法,优化制造资源.同时,提出了一种基于不完全知识和进化博弈理论的动态单元重构模型,它能够面向不确定的需求目标,采用自下而上和自上而下相结合的方法,快速生成稳定优化的可重构制造单元,从而实现敏捷车间的组织再设计.该模型求解采用协同进化算法,并通过实例,验证了该方法的可行性和有效性.

Dynamic workshop reconfiguration based on agile manufacturing cell

To adapt to agile workshop environment,a dynamic workshop reconfiguration approach based on agile manufacturing cell was presented.In this approach,the dynamic reconfiguration of workshop was described as a process of optimizing manufacturing resources,constructing product-oriented agile manufacturing cell and forming virtual workshop.Mathematical programming and fuzzy theory were used to represent selection and optimization problems of manufacturing resources.Then,a dynamic cell reconfiguration method based on incomplete knowledge and evolutionary game theory was established.It was designed to deal with uncertain requirements with full use of both the top-down and the down-top approach to form stable and optimized reconfigurable manufacturing cells and realize the redesign of agile workshop.Furthermore,a collaboration-evolution algorithm was designed to find the optimal solution of the reconfiguration model.Finally,the feasibility and validity of the proposed approach were verified by a case study,and the advantages of the dynamic workshop reconfiguration method were provided.
