At the end of the optimization algorithm, islands and generalized chaos will be healed. Weboptimality of (s, S)policies—policies that raise the net-inventory level to S every time it decreases to s—in inventory models with stochastic demand is almost exclusively limited to the ﬁxed-plus-proportional ordering cost structure. Scarf (1960), Veinott (1966), and Zheng (1991) are classical examples, and Table 1 church of the book

Web1 de dez. de 2024 · Iglehart [23] and Zheng [59] extend the optimal (s, S) policy to the infinite-horizon setting. Porteus [30] considers a concave increasing ordering cost function that encodes a quantity discount and verifies the optimality of a generalized (s, S) policy using the quasi-K-convex function. 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.
