WebOn the optimality of ( s , S ) policies in dynamic inventory models with finite horizon. SIAM J. Appl. Math. 30 518--537.). Our analysis is based in part on a generalization of quasi … 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. We replace Scarf’s hypothesis that the one period expected costs are convex by the weaker …

WebBy interpreting the first-order optimality condition of the reformulated problem as an eigenvector-dependent nonlinear eigenvalue problem, we reveal that the leading eigenvector of the derived optimality condition is a local optimal solution. To find the leading eigenvector, we propose an algorithm inspired by a power iteration. WebA generalized (s, S) policy is shown to be optimal in the ...

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. WebMoreover, we derive the Pareto-optimality condition for distributed policies that balance the variance and mean square of the service capacity. Finally, we discuss a scalable partially centralized algorithm that uses centralized information to boost performance and a method to deal with missing information on service requirements.
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
