WebThe existence of an optimal $ (s,S)$-policy is shown for the single product continuous review inventory model with infinite planning horizon. The demand process is assumed to be a superposition of a compound Poisson process and a continuous deterministic (state-dependent) process. WebIn this paper, we develop an economic order quantity (EOQ) model for fixed shelf-life items and a non-increasing demand. The objective of this model is to maximize the total profit. We find the criterion to decide (i) the interior maximum solution or (ii) the boundary maximum solution. Eight numerical examples are given to illustrate all possible scenarios of this …

"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. " - On the optimality of generalized s s policies
