سیاست شاهراه برای مدل موجودی بررسی ادواری با سفارش اضطراری

The minimum cost is obtained by considering this system as a discrete-time Markov decision process. We use this model to describe a simple and efficient value function algorithm for finding optimal policies. We find propositions on specially structured optimal policies generalizing classical results on (s,S)(s,S) policies. Some connections of the turnpike policies and optimal infinite policies are presented. Computational results are given through numerical examples.
