WebApr 23, 2024 · Once again, our starting point is a time-homogeneous, continuous-time Markov chain X = {Xt: t ∈ [0, ∞)} defined on an underlying probability space (Ω, F, P) and with discrete state space (S, S). By definition, this means that S is countable with the discrete topology, so that S is the σ -algebra of all subsets of S. WebMar 2, 2024 · The refuelling time can be modelled with an exponential random variable with mean 8 minutes for cars and 3 minutes for motorcycles, that is, the services rates are \(\mu_\mathrm{c}=1/8\) cars and \(\mu_\mathrm{m}=1/3\) motorcycles per minute respectively. This problem is described by the following continuous-time Markov chain:
