考虑混合不确定性信息的产品多属性方案评价

针对当前产品方案评价方法对随机性、区间性、模糊性等混合不确定性信息考虑不足,其量化过程没有真实反映产品方案本质属性的问题,提出产品方案评价中考虑混合不确定性信息的产品多属性方案评价方法.对混合不确定性信息进行精准表征,并构造容信度科学、精确量化混合不确定性信息;同时,构建基于混合不确定性信息容信度的产品方案评价模型,计算混合不确定性信息的容信度和理想度,利用方案优选定理实现产品方案的评价优选,并通过实例进行了验证.

Multi-attribute evaluation method for product scheme under hybrid uncertainty information

The hybrid uncertainty information is insufficiently taking into account in the existed evaluation methods of product scheme, such as, stochastic information, fuzzy information, interval information, and so on. The quantization process did not reflect the nature of the product scheme. So, the multi-attribute evaluation method for product scheme under hybrid uncertainty information is presented in this paper. First, the hybrid uncertainty information is accurate characterizes and calculates use the contains information content. Second, the evaluation model for product scheme based on the contains information content of the hybrid uncertainty information is constructed, and the contains information content and the ideal quantity are calculated. The optimal scheme is selected using the scheme optimization theorem. Finally, the evaluation method is verified by an example in this paper.
