Turnpike policies for periodic review inventory model with emergency orders
This paper presents a periodic review capacitated lot sizing model with limited backlogging and a possibility of emergency orders. The main intention of placing emergency orders is to satisfy the demand as soon as a shortage occurs. It is assumed that the demands are independently distributed in successive periods. There are two resupply modes available: a regular mode and an emergency mode. He...
متن کاملEmergency orders in the periodic-review inventory system with fixed ordering costs and compound Poisson demand
Emergency orders have shorter lead times but incur extra costs compared to normal orders. We present a discrete-time Markov decision model where normal orders are issued according to a reorder point policy with a fixed order quantity, whereas emergency orders are controlled by a state-dependent reorder point policy with a target stock level. A rapid policy iteration algorithm is used to find an...
متن کاملOptimal Control Policies for a Periodic Review Inventory System with Emergency Orders
We describe a periodic review inventory system where emergency orders, which have a shorter supply lead time but are subject to higher ordering cost compared to regular orders, can be placed on a continuous basis. We consider the periodic review system in which the order cycles are relatively long so that they are possibly larger than the supply lead times. Study of such systems is important si...
متن کاملA Capacitated Production-Inventory Model with Periodic Demand
For a single product, single-stage capacitated production-inventory model with stochas-tic, periodic (cyclic) demand, we nd the optimal policy and characterize some of its properties. We study the nite-horizon, the discounted innnite-horizon and the innnite-horizon average cases. A simulation based optimization method is provided to compute the optimal parameters. Based on a numerical study, se...
متن کاملA note on optimal policies for a periodic inventory system with emergency orders
In this article, we develop a dynamic programming model for a periodic review inventory system in which emergency orders can be placed at the start of each period, while regular orders are placed at the beginning of an order cycle (which consists of a number of periods). We assume that the regular and emergency supply lead times di!er by one period. We devise a simple algorithm of computing the...
