Table 1

Model parameters and variable.

	Symbol	Meaning
Set		Note set,  = {1, 2, …, n}, 1 as dispatch center
		= /{1} gathering for customer needs
	A	Collection of paths,
	S	Any subset of customer demand points,
	K	Vehicle assembly, , k for delivery vehicles
	K	Vehicle assembly, , k for delivery vehicles
Parameters	Q	Vehicle capacity
		Material demand at the demand point
		Demand point duration of service
		route mileage
		Car fixed start-up costs
		The travel time of vehicle k between iiE V path (i.j) e A
		Control parameter, a very large integer
		The unit travel distance cost of the vehicle k
		Arrive earlier than the time window, penalty cost per unit time
		Arrival later than the time window, penalty cost per unit time
		The lower limit of the time window of demand point i
		The upper limit of the time window of demand point i
Variable		The actual arrival of the vehicle at the demand point
		Decision variable, when node path between by vehicle . The value is 1; otherwise 0.
