基于软集理论的新产品开发创意方案选择方法

针对新产品开发创意方案选择问题,在考虑不同部门的评审专家关注不同的评价指标集的情形下,给出了一种基于软集理论的新产品开发创意方案选择方法。即:首先介绍了软集、软矩阵、两个软矩阵的∧积运算及极大-极小决策函数等的相关定义;然后通过对两个软矩阵的极大-极小决策函数进行有效扩展,给出了集结基于不同的评价指标集的评价信息的创意方案初选准则,并定义通过初选的各方案的优先序来选择最终方案。最后,运用算例说明了该方法的可行性和有效性。

Approach of Idea Scheme Selection on New Product Development Based on Soft Set Theory

According to the problem of idea scheme selection on new product development,this paper proposes a method of idea scheme selection based on the soft set theory under considering different evaluation criteria sets addressed by different department experts.Firstly,it introduces the definitions of soft set,soft matrix,∧-product and soft max-min decision function of two soft matrixes.Then by effectively extending the soft max-min decision function between two soft matrixes to multiple soft matrixes,it gives the rule of idea scheme selection to integrate the evaluation information based on different evaluation criteria sets,and determines the priority orders of selected schemes.Finally,it demonstrates the feasibility and effectiveness of the proposed method by using a numerical example.
