摘　　要：为有效地提高企业的快速响应能力、加工设备利用率与生产效率,降低企业产品设计与制造成本,提出产品零部件工艺相似性分析与产品模块构建方法.首先对产品零部件工序制定规则进行分析,采用模糊设计结构矩阵建立工艺约束关系,并在此基础上通过目标优化验证工艺序列的可行性;其次分析了产品零部件加工工艺序列模型,采用最大子相似序列集评价工艺序列的相似性,避免了因局部加工内容的不同导致的全局相似性误差;最后利用传递闭包法生成工艺序列相似零部件动态聚类过程.该方法已在机床制造行业中得到了实际应用,在满足客户需求的前提下有效地提高了产品设计与加工效率.To improve the rapid response ability,equipment utilization and production efficiency of manufacturing enterprise,a method of construction of product modules and analysis of process similarity is put forward.First,the process rules of parts among products are studied and analyzed,and fuzzy design structure matrix is used to create process constraints.The feasibility of process sequences is evaluated and verified based on optimization methods.Then,the process sequence model of product parts is analyzed,and the largest sub-set of similar sequences is applied to evaluate the similarity among product parts,which avoids the disadvantage caused by local dissimilarity.Finally,the dynamic clustering process of similar parts is established by the transitive closure method.As a result,this method has been successfully applied in the rapid response design of machining industry,and the efficiency of the product design is much improved.
