摘　　要：针对大规模定制中产品属性定制权重的确定问题,提出了基于属性重要度和依赖度的产品属性定制权重确定方法.在该方法中,产品关键定制属性构成条件属性集,客户对样本定制产品的偏好构成决策属性集,属性值的不同组合构成样本定制产品,通过论域自身所隐含的知识来确定不同属性对客户定制的影响程度,可以有效提高权重计算的客观性.研究了产品属性定制权重计算过程,其由产品定制属性分析、定量属性的离散化、基于客户偏好调查的决策表构建、产品属性定制权重计算构成.以汽车座套为例对所提出的方法进行了实例分析,验证了方法的有效性.An attribute significance and dependency based customization level decision method was proposed in order to solve the customization level decision problem in mass customization. The condition attribute set was composed of product＇s key customization attributes, and the decision attribute set was composed of customer＇s preference to the product. Different combinations of attribute＇s value represented the samples of customization product. Product attribute customization level was calculated according to the implicit knowledge in the universe in order to improve the decision＇s objectivity. The process for the method consisted of analyzing the product＇s key attributes and their possible values, discretizing the key attribute＇s val- ue, constructing the customization degree decision table by customer investigation, and calculating the attribute customization level. An example of car seat customization level decision shows that the method is effective.
