摘　　要：针对NPD项目复杂性各因素间具有的关联性以及传统评价方法的局限性,提出一种基于关联多属性的2-可加模糊测度方法来对NPD项目复杂性进行评价。在界定项目复杂性内涵的基础上,从产品复杂性、环境复杂性、组织复杂性和技术复杂性四个方面构建了NPD项目复杂性评价指标体系。从模糊测度、默比乌斯变换和交互作用系数间的转化关系出发,基于最大Marichal熵原则,提出了一种确定2-可加模糊测度值的新方法。利用Choquet积分作为集结算子,自下而上计算各候选方案的综合评价值。最后,通过具体算例说明了该方法的可行性和有效性。With respect to the interaction among some complexity indexes of NPD project and the limitation of traditional evaluation methods, the 2-order additive fuzzy measures method based on multi-attribute with interaction is proposed to evaluate the complexity level of NPD project. After defining the concept of project complexity based on the two main viewpoints of ontology and epistemology, the paper establishes the complexity evaluation index system of NPD project, which is composed of product complexity, environment complexity, organization complexity and technology complexity. By introducing the transformation relationships among the fuzzy measures, mobius representation and interaction index, a new method for identifying the 2-order additive fuzzy measures is proposed on the principle of maximum Mariehal entropy. Then the paper presents the Choquet integral as an aggregation operator to calculate the synthetical values of the alternatives from bottom to top. Finally, an example is given to demonstrate the feasibility and validity of the proposed method, which will reduce the diffieuhy in mak- ing decision for experts to some extent and have a relatively strong practicability.
