Static Integration Based on Stochastic P-Time Petri Nets of Maintenance Scheduling for Railway Transport Equipment

Table 1

Formulation of problem.

	Number of EMU (M) in railway transport network
	Number of travel operation of total weekly travel operation
	Starting time of travel operation of weekly travel operation
	Maintenance time allocated to a transport equipment (EMU) M in transport network
	Age of EMU in transport network
	Index of travel, , where m is the number of weekly travel operations
	Ending time of travel operation of weekly travel operation
	Maximum EMU age
