考虑指标期望的产品外观设计方案的选择方法

Selection on Product Appearance Design Alternative Considering Aspiration on Criteria

针对考虑指标期望的产品外观设计方案的选择问题,提出了基于证据推理的分析方法。在该方法中,首先,通过集结决策参与者关于各产品外观设计方案给出的感性评价信息,得到各产品外观设计方案的分布式群体感性评价值;然后,考虑硬性一致型、硬性优势型和允许违反型三种类型的指标期望信息,确定各产品外观设计方案对应于各指标的满意度的概率分布;进一步地,采用证据推理方法,计算各产品外观设计方案的综合满意度的可信度分布,并根据随机占优准则,进行产品外观设计方案排序;最后,给出一个实例分析,表明了方法的实用性和可行性。

Aim to the selection problem of product appearance design alternative with aspiration on criteria, an analytic method based on evidential reasoning is given. Firstly, the kansei evaluation information of each product appearance design alternative given by participants is aggregated into the distribution of the group kansei evaluation information. Then, considering three patterns such as hard consensus, hard strength and soft aspiration on criteria, the probability distribution of the saris{action degree about each criteria is calculated. Further, the credibility distribution of the comprehensive satisfaction degree of each product appearance design alternative is calculated by using the evidential reasoning method. And based on the stochastic dominance rule, the ranking result of product appearance alternatives is obtained. Finally, a practical example is given to illustrate the feasibility and validity of proposed method.
