面向产品族的制造单元聚类规划研究

为了支持用户的个性化需求 ,在分析产品族的模块化结构及其零部件构成比例等特点的基础上 ,提出了支持生产线布局规划的面向产品族的制造单元聚类规划方法 ,给出了聚类规划过程、聚类规划算法描述 ,并进行了应用分析。构建了零部件与工艺路线间的关联量化矩阵。利用聚类规划方法 ,获得了零部件的聚集分类及相关的聚集工艺需求、与零部件聚集相对应的制造单元的加工需求能力分配比例指标和制造单元间的交流等信息。最后在企业制造资源和工艺环节映射关系的支持下 ,形成了面向产品族的基于制造单元的生产线布局规划方法。本研究为企业的大规模定制生产模式下生产系统的规划提供了可行的思路

Research on clustering planning of machine cell for product family

In order to satisfy users' individual requirements, the clustering planning method of machine cell for product family was presented after analyzing module structure and its component proportion of product family. Subjected to the features of modular architecture and member composing proportion of product family, the composition modeling of product family was constructed and the relation matrix between part-component and process step was derived. Then, by using the clustering analysis method based on average linkage, the reasonable number of component aggregate cluster was obtained, and correspondingly, the quantity of manufacturing load of every process step for the total product within family with the special composing proportion was also calculated. Finally, the machine cell corresponding with each component category was derived by the tradeoff and allocation of enterprise resources to fulfill the load quantity of each step in the process. One experiment was discussed to illustrate the process. This method embodies the integration of design and manufacture and benefits the implementation of mass customization production based on product family.
