摘要
产品方案的评估方法是产品设计过程决策的重要依据。针对当前产品方案评估方法存在的不足,本文提出一种基于改进D-S证据理论的TOPSIS决策方法。首先,该方法采用灰色关联分析改进D-S组合规则知识来集成产品方案评价指标的主观权重和客观权重,避免了单一赋权法的不足。然后,采用基于评价指标权重融合的改进TOPSIS方法进行产品设计方案的评估。最后,以手机产品设计方案的评估为实例,验证了方法有效性。
The evaluation of product scheme is the important decision basis of product design process. Aiming at the shortcomings of the current product scheme evaluation methods, this paper puts forward a kind of improved TOPSIS decision-making method based on The D-S Evidence Theory. First of all, the method uses The Grey Relational Analysis to improve D-S combination rules knowledge to integrate subjective weight and objective weight of the product schemes evaluating indices in order to avoid the disadvantages of the single weighting method. Then, uses improved TOPSIS method based on the fusion of the weighing values to assess product design scheme. Finally, with the evaluation of mobile phone design scheme as an example, to verify the method is effective.
