Product Maturity and Its Fuzzy Evaluation Model Based on Entropy Weight-AHP

-Product maturity model is capable to plan and control concurrent product development process, which the accurately evaluation of product maturity is particularly important. For this purpose, product maturity model and the key factor architecture of product maturity was constructed from the perspective of the integrity of product information model. To determine the weight of the key factors, the calculation method which combines entropy weight method and AHP was proposed. And the fuzzy comprehensive evaluation was used to evaluate product maturity. The fuzzy evaluation model with entropy-AHP weight was established by integrating the above-mentioned methods. The rapid development of PDM technology guarantees the feasibility of implementation of this model.
