The Evaluation Model of Product Configuration Based on F-AHP

To help customers to estimate the result of product configuration during design, a new evaluation model was developed. Combining advantages of AHP and FCEM, the model took CSR as the goal, based on F-AHP. Dividing customer demands into different groups, the model had multiple structural layers. It took customer demands as target layers, evaluation indexes as criterion layers, and satisfactions as scheme layers. Triangular fuzzy membership function helped to define the relationship between the upper and lower level of structural layers. Then the method of weighted distance minimum integrated the weight of all experts for each criterion layer as the fuzzy weight of each layer. Linear weight integrated all expert evaluation. Finally, total utility of each evaluation was calculated from bottom to top, namely total satisfaction. So the maximum total utility was the evaluation result. Through analyzing the configuration result of grader, it verifies the feasibility of evaluation methods, and the rationality of the evaluation model.
