Moreover, we construct a new proof for part (iv) of the lemma, because the original proof relied upon the optimality of the (s, S) policies. This paper is concerned with a generalization of classical inventory models with fixed ordering costs that exhibit s, Spolicies. In our model, the distribution of demands in successive periods is dependent on a Markov chain. The model includes the case of cyclic or seasonal demand. dauntless offroadWeb1 de fev. de 2015 · It is shown that (s; S) policies are also optimal for the generalized model as well as its extensions, and is further extended to incorporate some other realistic features such as no ordering periods and storage and service level constraints. 253 View 1 … black actress named debbie
