WebScarf [6] has shown that the $( {s,S} )$ policy is optimal for a class of discrete review dynamic nonstationary inventory models. In this paper a new proof of this result is found under new conditions which do not imply and are not implied by Scarf’s hypotheses.

WebIn works devoted to the universe, the optimality of its evolution is noted. However, specific mathematical models, according to which the evolution of the universe takes place, are not given in them (see, e.g. [1] ). In the book [2] , instead of the optimality of the evolution of the Universe, the term “cosmic wisdom” is applied. greater new york regional na

A standard periodic review, stochastic, dynamic multiproduct inventory model is considered in which the ordering cost consists of linear portions for each product and a setup cost. This setup cost is incurred if an order is placed for any number of ...WebIn case we have detected optimality we will extract the potential minimizers with a truncated version of the Gelfand–Naimark–Segal construction on the optimal solution of the Lasserre relaxation. We prove also that the operators of this truncated construction commute if and only if the matrix of this modified optimal solution is a generalized Hankel matrix. flint masonryWeb(s*, S*) policy is optimal among all (s, S) policies and in fact among all policies altogether. Lemma 1 below characterizes this pair (s*, S*). This lemma is essentially taken from [14], but generalized for the case a < 1.
