A Research On The Scheme Of Comprehensive Maintenance "window" For Passenger Dedicated Lines

With the development of construction of the Passenger dedicated Line, the issues relating to transportation organization need to be solved urgently.The train on the Passenger dedicated Line has the feature of high density, high speed, and high maintenance standard. How to set the"window"in the train operation diagram to ensure the maintenance of public works, electrical engineering and contact system is one of the most important issues.The paper includes the following aspects:(1)The time of comprehensive maintenance"window"consists of the starting time, ending time and the duration. The duration of window depends on the necessary maintenance time of public works, electrical engineering and contact system. Determining the starting time of"window"can be described as the search problems in artificial intelligence, which can be solved by the computer simulation technology in the two-dimensional space.(2)The setting way of comprehensive maintenance"window"is studied here. From the views of security, the impact on the transportation organization, and the impact on the operational efficiency, the pros and cons of"window"are compared It provides a scientific basis for the determining the way of setting window.(3)The rationality of"window"linkage based on a railway network is studied here. The focus is how to match the"window"s among the cross-lines to minimize the effect on transport organizations;(4)Through the analysis of traffic demands of Zhengzhou-Xi'an Passenger Dedicated Line, a comprehensive"window"program for it is studied and presented.
