Abstract
AbstractThe size of railway out-of-gauge cargo is large, and the loading outline will exceed the railway gauges. In the actual transportation organization, how to choose a safe and economic transportation route is an important issue in the transportation of railway out-of-gauge cargo. The purpose of this paper is to solve the route selection problem of railway out-of-gauge cargo transportation, taking the safety distance and curve radius as constraints and railway capacity loss and transportation cost as objective functions to construct the route selection model considering gauge modification. And on this basis, a route search heuristic algorithm can be designed to solve it. The case verification shows that the most economical route for railway out-of-gauge cargo transportation can be derived based on the model and algorithm.KeywordsRailway out-of-gauge cargo (ROC)Transportation route selection (TRS)Railway gaugeRailway capacity lossTransportation costGauge modification
