Centralized Maintenance Planning and Layout for Components in Urban Rail Transit Train Systems
摘要
Abstract
Centralized maintenance of components in train systems is of great significance for maintenance efficiency improvement,resource allocation optimization,and operational cost-saving.Firstly,a series of components in trains fitting the centralized maintenance were selected.Then,to minimize the total round-trip distance of component transportation and the total cost of component maintenance centers,this paper proposed a centralized maintenance layout scheme optimization model for components.Finally,it validated the raised optimization methods with a case study of the actual urban rail transit network.The influence of two crucial parameters,weight coefficient and minimum pavement transportation distance limit,on the scheme was researched.The obtained results reveal a cost-saving of 50.25%on the cost for component maintenance centers at the price of a slight transportation distance increment.The weight coefficients are calibrated according to the preferences of enterprises on two optimization objectives,enhancing the adaptability of the obtained centralized maintenance schedule to the practical requirements.The application of limited transportation distance can match the optimum results to the practical requirement,ensuring the feasibility of the layout scheme.关键词
