Dynamic customer requirements analysis based on the improved grey forecasting model

To deal with the difficulty of the traditional house of quality (HOQ) in analyzing and manag- ing dynamic customer requirements, a method based on the improved grey forecasting model to analyze dynamic and future customer requirements was presented. First, a new optimization model based on the combination of the initial condition and the background value was proposed to improve the precision de- gree of the grey forecasting model. Then, a dynamic HOQ (DHOQ) framework was introduced to analyze dynamic customer requirements. The improved grey forecasting model was integrated into the DHOQ framework to fit and forecast dynamic customer requirements. The trend of the importance of each tech- nical characteristic could be monitored and analyzed using the DHOQ so as to fulfill dynamic customer requirements. Finally, a software system development case was provided to illustrate the applicability and validity of the proposed method.
