An Extension to the Economic Production Quantity Problem with Deteriorating Products Considering Random Machine Breakdown and Stochastic Repair Time
The recent advances in manufacturing systems motivate several studies to focus on Economic Production Quantity (EPQ) problem. Althuogh there are several extentions to the EPQ, this paper provides a new extension by considering some of the real world parameters like: (a) shortages in the form of partial backordering, (b) inventory can deteriorate stochastically, (c) machine can break down stocha...
متن کاملOn a production-inventory system of deteriorating items subject to random machine breakdowns with a fixed repair time
This paper considers the impact of random machine breakdowns on the classical Economic Production Quantity (EPQ) model for a product subject to exponential decay and under a no-resumption (NR) inventory control policy. A product is manufactured in batches on a machine that is subject to random breakdowns in order to meet a constant demand over an infinite planning horizon. The product is assume...
متن کاملA Production Model for Deteriorating Inventory Items with Production Disruptions
Disruption management has recently become an active area of research. In this study, an extension is made to consider the fact that some products may deteriorate during storage. A productioninventory model for deteriorating items with production disruptions is developed. Then the optimal production and inventory plans are provided, so that the manufacturer can reduce the loss caused by disrupti...
متن کاملJoint pricing, inventory, and preservation decisions for deteriorating items with stochastic demand and promotional efforts
This study models a joint pricing, inventory, and preservation decision-making problem for deteriorating items subject to stochastic demand and promotional effort. The generalized price-dependent stochastic demand, time proportional deterioration, and partial backlogging rates are used to model the inventory system. The objective is to find the optimal pricing, replenishment, and preservation t...
متن کاملOn a Stochastic Inventory Model with Deteriorating Items
We suggest a new inventory continuous time stochastic model for deteriorating items. We derive optimal operating characteristics of the expected cost per unit time under the assumption that demand in each replenishment cycle forms a regenerative process. We also present numerical examples. 2000 Mathematics Subject Classification. Primary 60K30, 60J10, 90B05.
