An optimal policy for deteriorating items with time-proportional deterioration rate and constant and time-dependent linear demand rate
(Islamic Azad University, South Tehran Branch, 2017-12-01)In this paper, an economic order quantity (EOQ) inventory model for a deteriorating item is developed with the following characteristics: (i) The demand rate is deterministic and two-staged, i.e., it is constant in ...

Accelerated decomposition techniques for large discounted Markov decision processes
(Islamic Azad University, South Tehran Branch, 2017-12-01)Many hierarchical techniques to solve large Markov decision processes (MDPs) are based on the partition of the state space into strongly connected components (SCCs) that can be classified into some levels. In each level, ...
