铁路货运OD模糊推算应用技术研究
Application Research on the Fuzzy Calculation Method of Railway Freight Origin-destination Trip Matrix
摘要
Abstract
Aiming at calculating a regional-area railway freight OD multi-source data and information were first analyzed. After matrix, the available a brief review, a multi-information OD calculation model based on fuzzy planning theory as well as a heuristic solution algorithm was presented. Then, aprior OD calculation method according to regional railway freight exchange table was introduced. A case study was done in Jiangsu province. It was proved that multi-source information could take advantage in regional railway freight OD calculation and improve the precision of the calculation method, especially when data was scarce. Compared with the other OD calculation models, the usefulness of the fuzzy mathematics method in solving the uncertainty problem caused by the introduction of multi-source information and the criticalness of weights of different types of data for accuracy of OD calculation were also proved.关键词
