矛盾网络分析的DEMATEL方法
发布时间：2018-07-15 16:05
【摘要】：在创新设计过程中,随着对初始问题分析过程的深入,会逐渐展开多个彼此关联、相互影响的矛盾,这些矛盾构成矛盾网络。正确地从矛盾网络中选择重要矛盾、根源矛盾以及核心矛盾,是解决设计问题的关键。在研究矛盾关系模式和矛盾网络求解策略的基础上,采用有向图来表达矛盾网络中矛盾之间的影响关系,提出矛盾影响度的计算方法,建立了以DEMATEL方法支持的根源矛盾和核心矛盾的选择流程,阐述了综合考虑矛盾重要度、原因度和中心度的矛盾选择的方法。以卷扬机初始问题展开的矛盾网络为例,验证了所提方法的正确性。
[Abstract]:In the process of innovative design, with the deepening of the process of initial problem analysis, a number of contradictions, which are related to each other and affect each other, will be gradually developed, and these contradictions constitute a contradiction network. It is the key to solve the design problem to select the important contradiction, the root contradiction and the core contradiction from the contradiction network correctly. On the basis of studying the model of contradiction relation and the strategy of solving contradiction network, this paper uses directed graph to express the influence relation of contradiction in contradiction network, and puts forward a method to calculate the influence degree of contradiction. The selection process of root contradiction and core contradiction supported by DEMATEL method is established, and the method of synthetically considering contradiction importance, reason degree and center degree is expounded. The correctness of the proposed method is verified by taking the contradictory network of initial problems of winch as an example.
