基于集对投影寻踪的轨道交通线路决策模型
Decision model of rail transit line based on coupling set pair analysis and projection pursuit
摘要
Abstract
Evaluation indicators for selection of rail transit line scheme index are mostly qualitative indicators with multiple and diversified characteristics, fuzzy and conversion uncertainties, so the rail transit line scheme optimization is a complex multi-attribute decision-making problem. Considering the above characteristics, the decision model coupling connection number theory with the projection pursuit theory was discussed. In this model, based on the index values, the identical degree of the connection number was firstly used to quantitatively describe the relationship between the evaluation scheme and the optimal scheme. And then through the projection pursuit model to calculate the projective value in order to select optimal scheme. Finally a case study and comparison with other methods were conducted to confirm the model proposed. The results show that the selection of optimal rail transit lines scheme based on the model is effective and feasible, and its processing procedure is simple. It can avoid the complexity of multiple index and high-dimensional data processing, and also provides a new reference for the similar uncertainty decision-making problems.关键词
