Abstract: This paper approximations to the transient probabilities Pij (t) (i, j=0, 1, 2, , n) for a transition from state i at t=0 to state j at time t in the n-channel birthdeath processes. First, P0n(t) is considered as an extension of Gnedenko's approximate expressions when state n is regarded as an absorbing state for the models M/M/1/n/, M/M/1/n/N, M/M/n/n/, and M/M/n/n/N. That is to say, if Pn is the steady-state probability of state n, the approximations P0n(t)/Pn when state n is not an absorbing state can be obtained from the function 1-exp{-Q(t)} (Q(t)0 is an analytic function). Based on these considerations, transition diagrams are derived to obtain P0n (t) for the models M/M/S/n/ and M/M/S/n/N. Finally, Pij(t) can be expressed with this P0n(t). Several examples show that the approximations of the transient probabilities are nearly equal to the exact values calculated numerically using the Runge-Kutta method on a personal computer. As the approximations in this paper are very precise and calculable instantaneously on a personal computer, they may be applicable for time-dependent traffic theory which will be useful, for instance, in real-time network management technology.
