A Plan for Passenger Train Operation Based on the Dynamic Allocation of Seat Types

Dynamic seat allocation is considered to formulate a plan for passenger train operation meeting the diversified needs of passengers,thus improving the service quality in the railway departments and the travel experience ofrailway passengers.From passengers and railway operation departments,this paper takes the minimum generalizedtravel time of passenger dynamics and the maximum railway revenue as the objectives and the conservation laws of passenger flow,interval through ability,and passenger flow volume demand as the constraint conditions. Besides,themulti-objective planning model is established. A Logit model is used to obtain the fixed number of passengers and theshare rates in the hard seat , hard berth, and soft berth. In the solving process , the share rates in various seats are constantly updated by the generated operation plan to realize the dynamic allocation of the three categories of seats untilthe results are obtained.'The example is solved using the non-dominated sorting genetic algorithm with elite strategy(NSGA-II) , and then the analysis of the example is carried out. The results show that the establishment of the plan forpassenger train operation considering the dynamic allocation of seat types has increased the passenger-railway servicerate by 3.5% and the railway's revenue by 1.5%,realizing the passenger's choice of seats.
