Service level constraint is often used as a metric to directly control the quality of service (e.g., managing the probability of stock-out) in practice. Many inventory problems with service level constraints are often difficult to solve and are typically approximated by deterministic...

Motivated by a platelet inventory management problem, we study periodic-review, fixed-lifetime perishable inventory systems where demand is a general stochastic process. The optimal solution for this problem is computationally intractable due to the “curse of dimensionality”. In this paper,...

This paper presents a travel time model for multi-deep AS/RS, which determines the average travel times during a single command storage or retrieval and a dual command cycle. The model can determine the relocation probability, the number of expected relocations and the travel times in storage...
