面向应急动员批产的流水式制造单元构建技术

Formation technology of flow-line style manufacturing cell for emergency mobilization batch volume production

针对国防应急动员批产生产线的规划问题,提出了流水式制造单元构建技术,建立了以产品生产节拍为核心的流水式制造单元构建目标模型。该模型通过对产品组合、生产批量和交货期的分析,确定了生产节拍和制造系统初始规模。利用成组聚类分析方法,构建了基于零件工艺路线相似性分析的初始制造单元。提出了基于启发式规则的工艺路线确定方法和设备资源优化分配机制。综合考虑零件是否为关重件,以及零件是否全部按期完成加工(齐套生产)和生产节拍等因素,实现了制造单元的优化调整,形成了设备共享能力定量分配方案的单元化制造系统。开发了软件系统,并通过实例验证了所提算法的有效性,为战时国防动员生产提供了可行的解决途径。

Aiming at the problems of the production line planning for Emergency Mobilization Batch Volume Production （EMBVP）, the formation methodology of flow-line style manufacturing cell was presented. Objective function model, which minimized the sum of the inter-cell working procedure number, the cell load ratio and the production step balance value, was constructed. By analyzing the multi-product-type combination, production volume and due data, production step was defined and initial capacity requirements of the manufacturing system was evaluated. Initial manufacturing cell based on component processing route similarity analysis was constructed by cluster analysis methodology. Methods of the production process confirmation and the machine priority allocation scheme based on heuristics rules were put forward. Manufacturing cell adjustment based on production step balance was carried out, and the quantitative schema for shared machine among manufacturing cells was generated. Finally, the feasibility of the method was validated by practical application.
