It is generally believed that mixed fleet operation in MRT systems can result in much efficiency under certain circumstances. But the solution to how fleets are mixed is very hard to obtain because the problem is somewhat involved, especially when the passenger demand is subject to random variations. The OOP (Object-Oriented Programming) technique has made it possible to construct and realize complex models easily. Simulation modeling using the properties of OOP can help, in this case, MRT operators in scheduling mixed fleets to deal with the problem of matching supply with time-varying demand. In this paper, a visual OOP simulation tool-AweSim was employed to construct an MRT's operation model of mixed fleets, which has made the work of model construction relatively easy. Taking into account the running time and capacity of each train type, this model can accomplish the tasks of train scheduling and, with slight modification, of timetable evaluation. As a result of scheduling train dispatches to achieve maximum system efficiency subject to the constraints of satisfying passenger demand and policy headway, the average waiting time of passengers is increased by 28-96 seconds compared to that of the current timetable. However, the suggested timetables, even still will all double-pair trains, can decrease the total Operation cost by 5.9%, and with the mixed-fleet operation by 43.6%.
