For fixed train composition,different trains in the same circulation plan provide the same transport capacity,which may lead to a waste of transport resources when different trains have different intensity of passenger travel demand.To rationally utilize transport resources,flexible train composition was adopted so that different trains in the same circu-lation can offer different seat capacities to match their different passenger demands.Based on the OD passenger demand of each train in a given train timetable,with the optimization objective of maximizing ticket revenue under limited elec-tric multiple-unit(EMU)resources,a flexible train composition circulation plan optimization model was proposed,which,as a nonlinear programming model,can be equally transformed into an integer linear programming for solution.The case study indicates that the circulation plan of flexible train composition can efficiently improve the utilization rate of EMUs and ticket revenue.With limited EMU resources,the ticket revenue of the flexible train composition circulation plan is 8.79％higher than that of fixed train composition circulation plan.
