Scheme evaluation on railway location design in mountains based on cloud model
摘要
Abstract
The scheme evaluation of mountain railway location design has the characteristic that it has many qualitative indexes .The traditional evaluation methods have not fully taken the uncertainty charac‐teristics of qualitative indexes into account ,and it also lacks of appropriate evaluation methods when qualitative indicators and quantitative indicators cross with each other . Firstly , the advantages of the cloud model in describing uncertain information were used to improve the traditional AHP .Combined with deviation method ,the subjective weight and objective weight of index were calculated respectively . Through a new weighted fusion mode ,the combination weight was formed .Then ,according to the prin‐ciple of uncertain reasoning of cloud model ,an effective quantification of qualitative indexes was achieved by using the cloud generator based on the evaluation about qualitative index made by experts using lin‐guistic variables .Finally ,the projection method was introduced to select the optimal scheme .Therefore , a new model of comprehensive scheme evaluation which contained both quantitative and qualitative inde‐xes was proposed ,and an example of local alignment scheme comparison was used to illustrate its feasi‐bility and practicability .It provides a new idea and method for the scheme evaluation of railway location design in mountains .关键词
