Performance Analysis of Two Different Types of Waiting Queues with Working Vacations

Algorithm 1

Algorithm to compute , , , and ETC.

	Begin
	Input: λ, a, , and θ.
	Compute: the value of ρ
	If (ρ < 1)
	Compute: Probabilities of system states
	Compute: Mean orbit and system size
	Compute: Mean busy time
	Compute: Expected total cost
	Else
	Change the input of the parameters by satisfying ρ < 1.
	End
	Output: , , and ETC
