Computational Analysis of Queues with Catastrophes in a Multiphase Random Environment

Table 2

The probability that the system resides in phase .

	Case 1		Case 2 [sensitivity analysis]
	Matrix Geometric Method	Probability Generating Function method	Matrix Geometric Method	Probability Generating Function method
	0.295605	0.296296	0.591879	0.592593
	0.590921	0.592593	0.591879	0.592593
	0.29603	0.296296	0.295917	0.296296
	0.078151	0.074074	0.073983	0.074074
	0.037353	0.037037	0.036704	0.037037

Note. We see that probabilities calculated by both methods remain the same for both the cases and for Case 2.
