Abstract:

Competition exists in multiple intercity transportation means. Ticket price is the adjustment lever for the given requirements. This paper presents a bilevel programming model for railway passenger ticket pricing. We initially construct a variational inequality model that can represent multiclass, multipath cost and multicriteria. It serves as the downlevel model of the bilevel programming model. We then establish the uplevel model of the bilevel programming model with total railway income as an object. We also design a chaosmodified projection algorithm based heuristic algorithm to solve a bilevel programming model. Results show that the proposed ticket pricing mechanism is reasonable. It will provide a better theoretical basis for government railway ticket pricing mechanism.

Key words: railway passenger ticket price, bilevel programming, variational inequality, solution algorithm
