摘　　要：用户可用性需求获取及权重确定是构建数控机床可用性屋的起点和关键,对于能否真实反映故障因素对可用性需求的最终影响起着重要作用。为有效评估用户可用性需求,提出基于改进AHP与熵权法的主客观赋权法、DEMATEL和Kano模型及数控机床"卖点"的合成分析法。采用AHP与熵权相结合的主客观赋权法确定基本权重;考虑用户可用性需求间相互影响,利用DEMATEL法得到修正权重;兼顾用户可用性需求水平提高率、Kano分类及数控机床"卖点"等市场竞争性评估信息,使所得权重调整因子与修正权重相结合,获取最终合成权重。最后借助实例对该方法的有效性与可行性进行了验证。The gain of user availability requirement and the weight determination is the starting point and key of constructing the CNC machine tool availability house.It plays an important role in reflecting the eventual impact of fault factors on the availability requirements.In order to evaluate the user availability requirements,this paper proposes a synthetic analysis method based on improved AHP and entropy weight method,Kano,DEMATEL model,and the ＂selling point＂ of CNC machine tools.The improved AHP and entropy weight methods are adopted to determine the basic weight of user availability requirements.Considering the mutual influence of user availability requirements,the DEMATEL method is used to modify the basic weight of availability requirements.Considering the level increase ratio of user availability requirements,Kano classification and CNC machine tool ＂selling points＂ market competitive assessment information,we make the adjustment factor combined with the correction weight,and get the final synthesis weight.Finally,the validity and feasibility of the method are verified by an example.
