基于信息熵的工程机械质量多属性决策

Multiple Attribute Decision of Engineering Machinery Quality Based on Info Entropy

针对工程机械质量评价过程中信息的不完全性和不确定性,引人指标分类权重概念,并采用信息熵进行定量描述,建立基于信息熵的多属性决策模型。应用该模型对液压挖掘机质量进行评价,对挖掘机的综合属性值进行排序和择优,结果与实际相符。

According to incompleteness and uncertainty of the info in the course of appraising the quality of the engineering machinery, the paper introduces the concept of index sorting weight, makes quantitative description by info entropy, and establishes multiple attribute decision model based on info entropy. It also applies the model to appraise the quality of hydraulic excavator, and sorts and selects the synthetic attribution of hydraulic excavator. The result consists with practice.
