An optimization model of EMU circulation problem for high-speed railway [PDF]
AIP Conference Proceedings, 2017 The electronic multiple unit (EMU) circulation plan schedule EMUs to perform train tasks based on a timetable while satisfying a number of constraints. This paper propose a model considering several constraints such as maintenance capability, accommodation capacity and maintenance management modes.
