铁路行李车开展零散货物快捷运输优化研究
Opti mization research on bu lk cargo express transport using railway baggage car
摘要
Abstract
Under the setting of sharp development of package quantity,the utilization of remaining capacity of baggage car in express transport was proposed.Based on the superiorities of railway passenger trains,such as small operation time interval and wide coverage in territory,a kind of multidimensional 0-1 knapsack model was established so as to solve the requirements of bulk cargo that are of multi-batches and limited quantities.Also, the greedy algorithm was designed based on the ‘First Departure First Loading’principle in order to more effec-tively use the remaining capacity of baggage car and dwell time.Lastly,an example was designed based on the data of railway passenger trains departing form Lanzhou station along Longhai direction in one day,the outcome explains that the utilization of remaining capacity of baggage car in express transport has the feasibility,necessity and realistic significance.关键词
