Railway public welfare comprehensive evaluation method based on fuzzy hybrid decision

Abstract

The invention discloses a railway public welfare comprehensive evaluation method based on fuzzy mixed decision. The method comprises the following steps: S1, establishing a railway public welfare comprehensive evaluation index system; S2, performing quantitative conversion on the qualitative indexes in the index system; S 3, respectively carrying out standardization processing on the values of thequalitative index and the quantitative index; S 4, calculating the weight of each index by adopting a G1 method; S 5, weighting each index value, and determining an ideal solution; S 6, calculating the distance between the railway to be evaluated and the ideal solution; and S7, carrying out comprehensive evaluation and grade classification on the railway public welfare. The railway public welfarecomprehensive evaluation method fills up the blank of the current railway public welfare comprehensive evaluation method, overcomes the defects of traditional railway evaluation methods such as national economy evaluation and fuzzy comprehensive evaluation methods, realizes the comprehensive evaluation of quantitative indexes and qualitative indexes, and enables the evaluation result to be more scientific and reasonable, and has higher reference value and operability.

Description

technical field [0001] The invention relates to the field of railway engineering construction, in particular to a method for comprehensive evaluation of railway public welfare based on fuzzy mixed decision-making. Background technique [0002] Carrying out research on comprehensive methods for public welfare will help clarify the complex factors and their interactions that affect the construction and operation of public welfare railways, fully understand the social contribution and construction significance of this type of railway, and expand the current economic evaluation system of railways. It plays an important role in realizing the scientific, reasonable, efficient operation and sustainable development of public welfare railways. [0003] At present, the research on the comprehensive evaluation of railway public welfare is still blank. Traditional railway evaluation methods are mostly limited to national economic evaluation or fuzzy comprehensive evaluation methods. H...

Problems solved by technology

However, the national economic evaluation method only considers limited quantitative indicators such as time-saving benefits and operating cost-saving benefits, and it is difficult to include qualitative indicators such as promoting national unity and maintaining national unity, and cannot give the final evaluation results. The fuzzy comprehensive evaluation method needs to give the evaluation grade or fuzzy evaluation value for both quantitative and qualitative indicators when performing comprehensive evaluation of quantitative and qualitative indicators, and determine the membership function, which makes it difficult to realize in many cases
