Abstract: We consider two applied discrete-time Markov control models: waiting times process in $\mbox{GI}\mid \mbox{D}\mid 1 \mid\infty$ queues with a controlled service rate and water release control in a simple dam model with independent water inflows. The stochastic dynamics of both models is determinated by a sequence of independent and identically distributed random variables with a distribution function $F$. In the situation when an available approximation $\tilde{F}$ is used in place of the unknown ${F}$, we estimate the deterioration of performance of control policies optimal with respect to the total discounted cost and the average cost per unit of time. For this purpose we introduce a stability index and find uppers bounds for this index expressed in terms of the Prokhorov distance between the distributions functions $F$ and $\tilde{F}$. When $\tilde{F} \equiv \tilde{F_{m}}$ is the empirical distribution function obtained from a sample of size m in average the stability index is less than a constant times $m^{\frac{-1}{3}}$. (More)
