摘　　要：针对当前通过传统质量屋进行用户需求向技术特性转化的方法对自相关矩阵的非对称性、技术特性间的自相关关系等处理能力较差的问题,提出一种基于改进质量屋模型的产品服务系统(Product service system, PSS)技术特性分析方法。采用功能特性交互图模型识别技术特性,然后将传统质量屋自相关矩阵的三角结构修改为矩形结构解决技术特征间的不对称问题,进而引入多粒度混合语言变量构建质量屋评价矩阵,实现技术特性相关关系的综合评估。案例分析结果表明:该方法在不丢失决策信息的前提下,有效解决了技术特性的冲突问题,也使质量屋的计算更加简便。The traditional house of quality(HoQ)has poor ability to deal with the asymmetry of autocorrelation matrix and the autocorrelation between technical characteristics while transforming user requirements into technical characteristics.In order to address these problems,a new method that based on an improved HoQ model for product-service system(PSS)technical characteristics analysis was proposed.Firstly,the interaction graph model for functions and characteristics was used to identify the PSS technical characteristics,and then the triangle structure of traditional HoQ autocorrelation matrix was changed to rectangular structure to solve the asymmetry problem of technical characteristics.Secondly,the multi-granularity mixed language variables were introduced to establish the HoQ matrix to evaluate the correlation of different technical characteristics comprehensively.Finally,a case was used to illustrate the feasibility of the present model and method.The results show that the present method can effectively solve the technical characteristics conflict without losing the decision information,and also make the calculation of the HoQbe more convenient.
