层次分析法以及模糊逻辑在PDM选型中的应用

Application of Theories of AHP and Fuzzy Logic in PDM Selection Method

通过应用层次分析法和模糊逻辑理论,提出了产品数据管理(PDM)软件选型的理论模型。主要是建立企业需求集合,用层次分析法为集合中的元素进行权重排序。然后基于PDM的知识构造模糊关系转换矩阵,根据推导的模糊映射算法实现从企业需求到功能需求,再从功能需求到商业软件的映射。PDM选型方法中层次分析法和模糊逻辑的使用将传统的定性的PDM选型方法转变为定量的选型方法。

Based on theories of AHP and fuzzy logic,a theoretical model of PDM selection is brought forward. At the beginning, enterprise requirements should be established,the elements of the requirements are ordered by importance through AHP. Then, based on the knowledge of PDM,fuzzy mapping matrix of relation is established,the mappings from enterprise requirements to functionality requirements and from functionality requirements to traditional software are conducted. It brings some advantages to apply AHP and fuzzy logic to PDM selection,it transforms traditional qualitative PDM selection to quantitative PDM selection.
