“…Section 7 introduces a sufficient condition for the weak continuity of transition probabilities for the COMDP that combines Assumption (H) and the weak continuity of H. Combining these properties together is important because Assumption (H) may hold for some observations and continuity of H may hold for others. Section 8 contains three illustrative examples: (i) a model defined by stochastic equations including Kalman's filter, (ii) a model for inventory control with incomplete records (for particular inventory control problems of such type see Bensoussan et al [4]- [7] and references therein), and (iii) the classic Markov decision model with incomplete information studied by Aoki [1], Dynkin [11], Shiryaev [30], Hinderer [21,Section 7.1], Sawarigi and Yoshikawa [27], Rhenius [24], Yushkevich [34], Dynkin and Yushkevich [12,Chapter 8], for which we provide a sufficient condition for the existence of optimal policies, convergence of value iterations to optimal values, and other optimality properties formulated in Theorems 3.2.…”
