Defining the input values in first house of quality of QFD method using fuzzy AHP method

Abstract

In this paper a problem of realization of customer demands in the design of cars B and C class was considered, the importance of using defined demands by using Fuzzy AHP (Analytic Hierarchy Process) method was respectively assessed. After defining characteristics, which should be provided in order to meet demands, the strength of the relation between each demand and each characteristic was assessed. Based on the relation between demands and characteristics, the first house of quality of QFD (Quality Function Deployment) method was formed, which refers to which of the products is considered better or worse, respecting each demand separately. In this way, the first house of quality of QFD method was upgraded by the application of Fuzzy AHP in decision making and assessing the importance of user demands.
