摘　　要：针对不确定性动态演进环境下产品族复杂系统运营状态评价问题,提出了基于模糊AHP和证据理论的产品族状态综合评价方法。从工程设计、市场需求-经济、生产能力和运营管理四个方面进行了产品族运行状态分析,在此基础上提出了产品族综合评价指标体系。采用模糊AHP获得各层次指标的权重值,并依据证据理论计算出各层指标的评价等级进而合成获得产品族状态的总评价等级。通过小型轮装产品族状态综合评价案例研究,验证了该方法的有效性。In order to effectively evaluate the running state of the complex product family system in dynamic evolution with uncertainty factors, a comprehensive evaluation method of the product family state is prop-osedbased on FAHP and the D-S Theory. Firstly, the issue of running state in the product family evolution process is analyzed from four aspects of engineering design, market demand-economy, production capacity and operations management, and on that basis, the comprehensive evaluation index system of the product family running state is established. Then, the weight coefficient of the index in each level is obtained using FAHP, andthe qualitative and quantitative analysis methods are combined to make the evaluation process more objective, the evaluation rating of indexin each level is calculated according to the D-S Theory, then the overall rating of the product family running state is acquired synthetically. Finally, the effectiveness of this method is verified by the case study of the running state of the small size wheel loader family.
