We consider a single-echelon, single-item inventory system where both demand and lead-time are stochastic. Continuous review policy is used to control the inventory system. The objective is to calculate the reorder point level under stochastic parameters. A case study is presented in Neonatal Intensive Care Unit. Keywords—Inventory control system, reorder point level, stochastic demand, stochas...

This paper considers a single-echelon, continuous review, inventory system with a warehouse facing compound Poisson customer demand. The replenishment lead-time is constant. Demand that cannot be met directly is backordered. There are standard linear holding and backorder costs but no set-up or ordering cost. It is assumed that the demand process starts at a certain given time. Consequently, be...

In this paper we consider a periodic review order-up-to-level (or base stock) inventory control system under normally distributed demand. For such circumstances an expression for the exact fill rate (fraction of demand satisfied without backordering) has been available in the literature but has not been widely known, let alone used by practitioners. In this paper we redevelop the expression and...

radio frequency identification (rfid) is used to identify the characteristics of an object wirelessly using radio waves. the purpose of this technology in this study is mainly focused on healthcare for inventory management and theft control replacing the manual logs. the storage and tracking of high-cost inventory items is developed. automatic reordering and billing interfaces are designed for ...

In this paper, we propose a simple heuristic approach for the inventory control problem with stochastic demand and multiplicative random yield. Our heuristic tries to find the best candidate within a class of policies which are referred to in the literature as the linear inflation rule (LIR) policies. Our approach is computationally fast, easy to implement and intuitive to understand. Moreover,...

We consider the problem of determining the optimal ordering and reordering policy for an inventory where the entire stockwill simultaneously become obsolete at some (typically random) time, T . Manymanufacturing, publishing, distribution, and high tech businesses face the challenge of maintaining inventories that do not age in the conventional sense; instead, they suddenly become obsolete and l...
