摘　　要：针对机械产品属性之间存在关联性问题,提出考虑属性组合关联的机械产品属性识别方法。将机械产品属性集看作粗糙集信息系统,考虑约简属性组合对条件属性的关联性,利用DEMATEL方法得出属性权重并结合正域依赖度计算约简属性组合重要度;考虑约简属性组合对决策属性的关联性,利用互信息理论计算约简属性组合的相关度。在此基础上,建立机械产品属性约简多目标0-1规划数学模型。提出改进多目标布谷鸟算法,给出鸟巢编码方式、sobol的鸟巢初始化、基于遗传交叉算子的鸟巢更新策略并借助区间犹豫模糊集对Pareto前沿优选,确定最优方案。最终以电梯产品属性约简为例,验证了所提出方法的有效性和可行性。Aiming at the problem of the correlation between the attributes of mechanical products,a method of attribute recognition considering the association of attributes combination is proposed. The attribute set of mechanical products is regarded as the information system of rough set. Considering the correlation between reduced attribute combination and conditional attribute,the attribute weight is obtained by DEMATEL method and the importance of reduced attribute combination is calculated by combining the positive domain dependence. Considering the correlation between reduced attribute combination and decision attribute,the correlation degree of reduced attribute combination is calculated by mutual information theory. On this basis,a multi-objective 0-1 programming mathematical model for mechanical product attribute reduction is established. The improved multi-objective cuckoo algorithm was proposed,the nest coding mode,the nest initialization of SOBOL,the nest updating strategy based on the genetic crossover operator,and the Pareto front optimization was selected with the help of the interval hesitation fuzzy set to determine the optimal scheme. Finally,the effectiveness and feasibility of the proposed method are verified by taking the elevator product attribute reduction as an example.
