基于云模型的高速铁路引入铁路枢纽线路方案优选研究
Research on the railway location optimization selection for Introducing high-speed railways to railway hubs based on cloud model
摘要
Abstract
In view of the multi-dimensional environmental impacts,various constraints,and diverse evaluation objectives experienced by designing schemes for the introduction of high-speed railway into railroad hubs,establishment a scientific decision-making model becomes a key problem that needs to be solved urgently.With the goal of seamless connectivity,stable operations,optimal performance,and cost-effectiveness,30 indicators were selected from five dimensions to establish a hierarchical index system for the optimal introduction of high-speed railways into railway hub line.The improved golden section method and cloud modeling theory were employed to systematically quantify qualitative indicators,which were then transformed into a gray correlation coefficient matrix.This matrix measures the discrepancies and uncertainties in decision-making information while also assessing the degree of convergence with the trend changes in the target sequence.To provide scientific,objective,and accurate decision support,a comprehensive decision model for route planning was established by integrating the VIKOR method and the improved closeness value method,which were driven by objective data.This model enables a comprehensive evaluation of alternative schemes from various perspectives.Based on an in-depth analysis of the interests and adverse consequences of the five stakeholders along the route,the Pythagorean fuzzy cloud model was introduced to optimize the deficiencies caused by the limited rational behavior of stakeholder groups.By incorporating the idea of approximating the ideal solution ranking,a route planning decision model driven by solution preference was established,thereby enhancing the feasibility and acceptability of the proposed schemes.Finally,the decision-making process considered the information value of objective data and program preferences to guide the selection of programs.The model was then validated using engineering examples.The results show that the decisions made based on this model demonstrate favorable consistency with the actual engineering outcomes,validating the reliability and applicability of the model.This provides theoretical support for the optimization design of railway hub line plans with the introduction of high-speed railways.关键词
