QFD 中客户需求权重确定的区间二元语义方法

摘要

Customer requirement weight is the key stage in the quality function deployment.Based on different language calculations made by different customer requirements assessors,the paper proposes a multi -attribute calculation method based on the normalized interval 2 -tuple linguistic information.It defines the interval 2 -tuple linguistic information,the aggregation operator and the method of possibility degree ranking,and introduces the fuzzy multi -attribute information cal-culation method based on the interval 2 -tuple linguistic informaiton.Finally,through the examples,it proves the feasibili-ty of the method.%客户需求权重的确定是质量功能展开中最关键、最核心的阶段。针对客户需求评价者可能作出的不同语言评价集，提出一种基于标准化区间二元语义的多属性评价方法。定义区间二元语义、集结算子和可能度排序方法，介绍基于区间二元语义模型的模糊多属性信息评价算法，并通过实例验证该方法的可行性。
