The finite state Markov processes with replacements are given in connection with the point processes. The marked point process with rewards is considered with marks \(\ell =1,...,q\) such that \(\ell \sim(i,k)\) means the transition from state i into state k, \(\ell \sim(i,+k)\) means the replacement (the instantaneous shift of the trajectory from state i into state k) and \(\ell \sim(i,k,+k')\) means the transition \(i\to k\) and in the same moment the replacement \(k\to k'.\)
A compensator (integral from the intensity) \(\{\) \(\tilde A_ t,t\geq 0\}=\{^ 1\tilde A_ t,...,^ q\tilde A_ t\}\) of the process is investigated if the process is under such a stationary replacement policy of destination f, under which one class of recurrent states exists only. Next there is considered the compensator \(\{A_ t,t\geq 0\}\) of the process under a common replacement policy F. Let \(R_ t\) be the reward from the process up to the time t and \(\theta\) the mean reward per time unit.
Theorem 1: If \(\lim_{t\to \infty}(^{\ell}A_ t-^{\ell}\tilde A_ t)=0\) F-almost sure holds for all \(\ell =1,...,q\) then \(\lim_{t\to \infty}t^{-1}R_ t=\theta\) F-almost sure. In Theorem 2 there are proved conditions under which \(t^{-1/2}(R_ t-\theta t)\) for \(t\to \infty\) has asymptotically normal distribution N(0,\(\xi)\), where \(\xi\) is a certain constant.
