Automatic Preparation of Pick-Up and Delivery Operation Schedule for Tree-Shaped Special Railway Line of Freight Station
摘要
Abstract
Reasonable arrangements for pick-up and delivery vehicles of special lines are the key to ensuring efficient loading and unloading operations in the daily work of railway freight stations.The traditional pick-up and delivery operation schedule relies on manual experience,which is inefficient and fails to cope with complex requirements.To optimize the sequence of single locomotive pick-up and delivery for tree-shaped special lines,the constraints of operation time window were considered to ensure freight timeliness in this study.By dividing the daily schedule into batches,constructing an optimization model for pick-up and delivery operations with time windows,and utilizing an improved genetic algorithm to solve the model,the selection,crossover,and mutation operations of the algorithm were optimized,and the efficiency and accuracy of the solution were improved.The experimental results show that the model effectively optimizes the pick-up and delivery sequence,reduces operation time and costs,and improves operation efficiency.By verifying the feasibility and superiority of the model and algorithm,the case analysis provides theoretical support and application value for the automatic scheduling of railway freight stations.关键词
