Uncertain multi-attribute optimal selection method taking prospect theory into account for expressway route schemes

Abstract

The invention discloses an uncertain multi-attribute optimal selection method taking a prospect theory into account for expressway route schemes. The method includes the steps of firstly, classifyingroute scheme indexes according to a real number type, a sectional type and a language type and carrying out data standardization processing; secondly, converting the attribute values of the route scheme indexes after standardization into prospect decision matrices; thirdly, using entropy weight to describe the contribution rates of the index attributes in route scheme optimization; finally, on thebasis of initial attribute values, prospect values and the entropy weight of the indexes, creating a comprehensive optimization degree evaluation model, and ranking the schemes according to the comprehensive optimization degree values to determine the optimal scheme. By adopting subjective experience of a decision maker as an attribute for carrying out objective analysis, high subjectivity is avoided, the situation that completely objective practical analysis cannot be combined during the optimal selection is avoided, an objective and feasible analysis method is provided for optimal selectionof expressway routes, and the difficulty that indexes in traditional methods cannot be quantized is solved.

Description

technical field [0001] The invention belongs to the field of comparison and selection of road route schemes, and in particular relates to an uncertain multi-attribute optimization method for expressway route schemes considering prospect theory. Background technique [0002] Highway is an important infrastructure project, and route scheme comparison is the core of highway route scheme optimization. The comprehensive comparison and selection of highway construction route schemes is an important problem that needs to be solved in the early stage of highway construction. Whether the selection of the basic direction scheme is reasonable will directly affect whether the project can meet the needs of national economic construction after the completion of the project, and affect the quality of line design , project cost and operating conditions, and ultimately determine the economic benefits of an expressway. Especially in our country, road transportation undertakes the main transp...

Problems solved by technology

There are two main types of traditional route scheme comparison and selection methods: one is too subjective, based on the economic indicators of the scheme, decision makers determine the optimal scheme after making subjective judgments on society and the environment; the other is excessive pursuit of objectivity and mechanically applying mathematical methods , does not consider the characteristics of the actual project, and cannot use the years of practical experience of the decision-maker in the decision-making of program comparison and selection
