摘要
目的研究不确定信息背景下产品包装方案的综合成本测度,实现产品包装方案的优选。方法对产品包装方案综合成本测度指标体系进行层次化建模;采用隶属度的方法对测度指标的初始评分值进行规范化处理,引入权重来实现对各测度指标重要程度的区分;将备选包装方案视为辨识框架中的焦元,计算各测度指标下所有焦元的加权基本概率分配值,并进行两阶的Dempster合成,最后基于信任区间进行备选包装方案综合成本的测度。结果通过某小型电气控制柜包装方案综合成本测度的案例应用,识别出最优的包装方案,验证了所提出方法的有效性和可行性。结论所提出方法能够为专家评分含有不确定信息时的产品包装方案综合成本测度提供了一种解决思路。
The work aims to study the comprehensive cost measurement of product packaging alternative in the uncertain information environment and realize the optimization of product packaging alternative. The hierarchical model of the comprehensive cost measurement index system was established, and the membership degree method was applied to standardize the initial score value of measurement index. The weight was introduced to distinguish the importance of each measurement index. The packaging alternatives were considered as the focal elements in the identification framework, and the weighted basic probability assignment value of all focal elements under each measurement index was calculated for the two-order Dempster combination. Finally, the comprehensive cost of the packaging alternatives was measured based on the confidence interval. A case study of the comprehensive cost measurement of packaging alternatives of a small electrical cabinet was carried out and the optimal packaging alternative was identified, so that the feasibility and effectiveness of the proposed method were verified. The proposed method can provide a solution to the comprehensive cost measurement of product packaging alternatives with uncertain information on the expert scores.
