Optimization Research Of Travel Choice Services Plan And System Based On Utility Maximization Of Railway Passenger

The paper is based on maximizing the utility of railway passengers, the author created a choice-model of trip’s planning which based on maximizing the utility of railway passengers, the model aimed at generating the best trip’s planning for passengers of different income levels, moreover, results of theoretical studies will be applied to the inquiring system of trip’s planning of railway passengers. The researching purpose of this paper is to provide perfect inquiry services for railway passengers. The major works is summarized as follows:First, the author analyzed the impact factors of railway passengers’trips, picked up Travel time, Ticket price, Comfort, Departure time and Arrival time as the serious impact factors, then quantified these factors.Second, the author designed a simplified transfer network of railway passengers which based on the online train schedules. Based on the transfer network, abstracted the problem about selecting trip’s plans of railway passengers as the problem about finding the shortest path of graph theory in Operations research. Created a choice-model of trip’s planning which based on maximizing the utility of railway passengers, and based on Matlab, developed the K_shortest path algorithm program which could solve the model.Third, decomposed the specific steps of solving the model, and made some detailed introductions about dealing ways of the key issues in the process of solving the model. The researching case is from Lanzhou to Fuzhou, according to the steps of solving the model, found out the best trip’s plan which maximized the utility of those passengers.Finally, briefly introduced the developing situations of the inquiring system of trip’s planning of railway passengers which being developed at present, and combined the researching case of this paper, showed partial functions of the system in current.
