- Abstract
Track utilization is the core of operations in regional railway stations and there are mutual influences among neighbor stations track utilization by train running to varying degrees due to abnormal incidents at certain places. Thus, it’s crucial to make multi-station track utilization plans with strong anti-disturbance ability, which is the important content to make train operation plans. In this paper, considering its influence factors and from the overall and plan-making perspectives, the redundant time concept was introduced and a track utilization redundant time distribution optimal model was built. Also, a track utilization plan integrated model was put forward to maximize its anti-disturbance ability and equilibrium. Then, by taking regional railway train running and arrival-departure time as links, a bi-level programming model of track utilization plan was provided based on redundant time. In addition, by constructing the probability function of random interference of abnormal events, the redundant time distribution optimal algorithm for multi-station track was designed. Further, a track utilization coordinative optimal algorithm base on simulated annealing was proposed and a new track utilization plan coordinative optimal method for regional railway stations based on redundant time was given. The calculation results show that the proposed method can make track utilization plans with strong anti-disturbance ability for neighbor railway stations and relieve abnormal incidents’ influences for following stations effectively; compared with the tradition proportion and mean assignment methods, the new redundant time distribution method is better to relieve mutual influences; the proposed method can provide strong supports for regional railway dispatchers to make track utilization and train operation plans coordinately.
