Evaluating Product Scheme Method Based on QFD and Euclid Norm

Abstract:

In order to establish the scheme evaluation model oriented to customer satisfaction through the product life cycle,the traditional quality function deployment(QFD) is improved to actualize the waterfall disassembling.Since the attribute weight plays a vital role in the following evaluation,IQFDE method is brought forward to acquire the weight of each attribute.Analytic hierarchy process(AHP) is used to get the first weight,then the entropy theory is used to obtain the revised weight.In this way,the purpose of combing the subjective and objective weight together is fulfilled.Because the spare schemes own the fuzzy characteristic,the Euclid norm is used to sequence the schemes.It can be testified by the case that the method of IQFDE and Euclid norm can acquire the best scheme oriented to the customer satisfaction.
