Optimization Model for Maintenance Window Design of Marshalling Yard Based on Basic Maintenance Window Unit
摘要
Abstract
A large number of trains in many directions,and frequent locomotive changing and shunting operations in marshalling yards,directly affects the construction and maintenance operations.It is difficult for the existing maintenance window design with fixed duration to balance the maintenance and the continuity of transportation work,resulting in a low availability rate of the maintenance window and more potential safety hazards.This paper proposed an optimization method for the maintenance window design of marshalling yard based on the basic unit of the maintenance window.Firstly,this paper,based on the operation characteristics of each maintenance work,the number of marshalling yard staff and the efficiency of each maintenance work,proposed the division of the basic unit of the maintenance window.Secondly,considering the maintenance and transportation organization requirements of marshalling yards,and aiming at the optimal utility,job completion rate and maintenance window threshold utilization rate,with the timing relationship as the constraint,this paper established a multi-objective optimization model of the threshold-based maintenance window design,with the mathematical software used to solve it.Finally,a case study based on Chengdu North Marshalling yard was conducted to verify the effectiveness of the model.The results show that by rationally optimizing the maintenance window design,the availability rate of maintenance windows reaches 100%,alleviating the conflict between maintenance and transportation at marshalling yards.关键词
