Abstract: We suggest a heuristic solution procedure for Partially Observable Markov DecisionProcesses with finite action space and finite state space with infinite horizon. The algorithmis a fast, very simple general heuristic; it is applicable for multiple states (not necessarilyordered) multiple actions and various distribution functions. The quality of the algorithm ischecked in this paper against existing analytical and empirical results for two specific modelsof machine replacement. One model refers to the case of two‐action and two‐system stateswith uniform observations (Grosfeld‐Nir [4]), and the other model refers to a case of manyordered states with binomial observations (Sinuany‐Stern et al. [11]). The paper also presentsthe model realization for various probability distribution functions applied to maintenanceand quality control. Copyright Kluwer Academic Publishers 1999
