Optimization Design Of Regional Passenger Train Operation Plan

The operation scheme of regional passenger train is an important part of railway transportation organization, it contains the operation scheme of different types of passenger train in region and relates to the rational use of railway fixed equipment and mobile devices,how to make a reasonable and feasible operation scheme of regional passenger train is the core problem that needs to be solved urgently. The formulation of the operation scheme of regional passenger train has very important practical significance on promoting rapid and stable development of regional economic, accelerating urbanization and modernization construction of China, coordinating urban and rural development and meeting the different needs of passenger travel. Therefore, it is necessary to study the formulation and optimization of the operation scheme of different types of passenger train in region and improve relevant theories and methods.The optimization of the operation scheme of regional passenger train involves many influence factors and segments. Among them, passenger flow is the basis of the operation scheme of regional passenger train, different kinds of passenger flow decide travel demands and the choices of train. Based on analyzing domestic and external research results on the operation scheme of train. Firstly, according to the travel demands of region passenger to divide passenger into different levels, and then obtain types of train that passengers in different levels choose it firstly, define generalized cost of passenger travel, according to the historical data of regional passenger travel in different levels to get generalized cost of passenger travel, from the waiting time of passenger, train attendance and other aspects to optimize values of generalized cost. Secondly, analyzing influence factors and principle of the formulation of the operation scheme of regional passenger train, on the basis, as a target for the maximum of the railway sector revenue and the minimization of generalized cost of regional passenger travel to establish comprehensive optimization model of the operation scheme of regional passenger train, by optimizing different kinds of operation scheme of regional passenger train to obtain generalized cost of passenger travel and compare it with proposed values,both error is optimal in a certain range,or re-optimize their values. Finally,taking Chengdu-Chongqing region as an example, by analyzing comprehensively regional transport situation to solve the model of operation scheme of the existing types of train in Chengdu-Chongqing region, then obtain the regional comprehensive operation scheme and analyze the result to verify the effectiveness of the model and algorithm.
