针对复杂产品设计方案具有多属性、层次性的特点,对方案设计多属性决策问题进行了研究,提出了一种基于可拓理论的多属性可拓决策方法,建立了一种基于综合可拓距的的多属性可拓决策模型,该模型通过引入并改进可拓距,基于设计方案决策信息的正负可拓域建立决策方案的综合可拓关联度,进而获得最优决策方案.最后,通过实例对模型和方法的有效性和可操作性进行了验证.
Aiming at the multi-attribute and multi-level design of complex product design scheme, the multi-attribute decision-making problem of scheme design is studied. A multi-attribute extension decision-making method based on extension theory is proposed, and a multi-attribute extension decision- , This model constructs the extension relational degree of the decision-making scheme based on the positive and negative extension domain based on the decision-making information of the design scheme by introducing and improving the extension distance, and then obtains the optimal decision scheme.Finally, The examples verify the validity and operability of the models and methods.
