摘　　要：为提高定制企业工时定额制定的效率以满足顾客对产品交货期的需求,提出一种新的工时定额计算方法。该方法以产品族的结构组成为基础,将产品族加工时间分为静态工时、柔性工时、特有工时三大工时模块,提出了时间模块的概念,并运用可拓变换的思想对柔性工时模块进行了可拓学描述,运用工艺聚类分析实现了各工时模块时间的计算。通过对制造对象物元的三级匹配搜索和事元的匹配搜索提取相似的制造对象,以实现加工时间的快速重用。最后通过实例验证了方法的可行性和有效性。To improve the efficiency of time quota formulation of enterprise to custom and satisfy the customer＇s demand of product delivery,this paper proposed a new calculation method of time quota.It took the product family＇s structure composition as a foundation,divided the process time of product family into the following three time modules： static time,flexible time and unique time,then proposed the concept of time module and carried out extension description to the flexible time module with extension theory to realize the calculation of time module by the process cluster analysis.Extracted similar manufacture object through the third-level match search of the object element and the match search of matter element,to realize rapid reuse of manufacturing time.Finally,it provided an instance to illustrate the feasibility and validity of the method.
