Fuzzy theory and AHP applied to urban rail transit operation opinion

Increasingly, urban rail transit has become the focus of Social Economic Development. This paper sets up an analysis model of urban rail transit arrangement based on the application of Delphi and Analytical Hierarchy Process and analyzes the shortcomings of analytic hierarchy process. Furthermore, this paper proposes a design of a more comprehensive and more scientific evaluation index system of urban rail transit performance assessment. The proposed system calculates every index weight using the weighting method—G1, which is based on differential principle; it appraises comprehensive performance using fuzzy comprehensive evaluation method. Verification of the proposed system was done by conducting an experiment using the Shanghai rail transit systems to measure its performance status. Results provide the theoretical foundation for development and correction of Shanghai urban rail transit system.
