摘要

According to the definition of daily transport production quality, the evaluation index system of daily transport production quality was constructed. Firstly decision matrix was built with the attribute value of each sample and the decision matrix was standardized. This paper analysed the sample data to obtain each principal component's values and weight through the principal component analysis and thus to get the optimal value and worst value of each principal component. Then this paper defined four parameters according to the grey relational analysis theory and gave the corresponding calculation method. Finally this paper defined the grey relative closeness coefficient parameter which was used to evaluate transport production quality based on TOPSIS. The method was applied to the Beijing railway bureau. This paper compared the results to those of the principal component analysis and grey correlation analysis, which proved that the method had certain feasibility.
