Optimization method of assembly gap decision based on mixed integer programming

为建立基于粗糙集的混合整数规划模型,研究柴油发动机装配间隙参数和整机质量等级之间的关系。首先数据预处理采用多重插补并进行相关性分析,运行主成分分析法进行处理。其次建立基于粗糙集的混合整数规划模型,最后与基于粗糙集的K均值聚类分析方法比较,得出基于粗糙集的混合整数规划模型的决策系统精度更高。

In order to establish a hybrid integer programming model based on rough set,the relationship between the assembly gap of diesel engine and the quality of the whole machine is studied.First,the data preprocessing adopts multiple interpolation and correlation analysis,and the principal component analysis method is used to deal with it.Secondly,a hybrid integer programming model based on rough set is established.Finally,compared with the K-means clustering analysis method based on rough set,the decision system of mixed integer programming model based on rough set is higher.
