Redesigning a Cellular Manufacturing System to Handle Long‐Term Demand Changes: A Methodology and Investigation*
提出一种基于模型的启发式单元系统重新设计方法论,用于应对长期需求变化,并通过文献数据集验证,识别出能以最低成本应对需求变化的单元设计特征。
ABSTRACT Cellular manufacturing systems have been proposed as an alternative to the job shop since they provide some of the operational benefits of a flow line production process, while retaining to some extent the flexibility of job shops. However, this must be balanced against the possibility of additional initial investments in equipment to form the cells and a certain loss in manufacturing flexibility, particularly in terms of the ability to deal with long‐term demand changes. This paper presents a model‐based heuristic cell system redesign methodology to deal with such demand changes. The methodology is validated and applied to system designs generated from several data sets published in the literature. Results show that different kinds of demand changes incur distinct kinds of costs. Further, characteristics of cell designs that can handle long‐term demand changes at least cost are identified.
