Abstract:Considering the weights of customer demands accounted by rough set may be equal or equal to zero, so that the technical designers can not accurately grasp the customer's attention to the various modules of the product in the process of product configuration. In order to avoid this problem and determine the weights of customer demands in product configuration reasonably, this paper puts forward an integrated analysis method based on rough set and fuzzy analytic hierarchy process (FAHP). Through combining subjective and objective methods, this method improves the accuracy of customer demands weights greatly. Firstly, by using rough set, this paper determines the preliminary weights of customer demands. Then in order to improve the preliminary weights of customer demands and to solve the problem that they may be equal or equal to zero, this paper uses FAHP to consider the self-correlation of customer demands deeply. Finally, this paper chooses the reasonable subjective and objective weight preference coefficient and uses linear weighted combination method to combine the weights of objective and subjective customer demands, so we can get the final weights of customer demands. In the end, the feasibility and effectiveness of this method is verified by a specific product customization.
