Optimal inventory policies under product obsolescent circumstance

Optimal Inventory Policies under Stochastic Production and Demand Rates

We consider a single stage production-inventory system whose production and demand rates are modulated by an environment process modeled as a finite state Continuous Time Markov Chain (CTMC). When the inventory level reaches zero, an order is placed from an external supplier, and it arrives instantaneously. We derive an Economic Order Quantity (EOQ ) policy that minimizes the long-run average c...

Optimal Inventory Policies for Assembly Systems Under Random Demands

Optimal inventory policies for successive generations of a high technology product

Available online 28 August 2014 In today's era of globalization, periodically new products with better value and added features are introduced into themarket. The rapid technological breakthroughs are creating significant risks of obsolescence at the product level. It creates enormous challenges to coordinate between technologymanagement and inventory control policies. Due to the dynamic nature...

Optimal and near-optimal inventory control policies for a make-to-order inventory-production system

This paper examines several inventory replenishment policies for a make-to-order inventory–production system that consists of a production workshop and a warehouse. Demands arrive to the production workshop according to a Poisson process, and are processed in an FCFS manner. The production workshop requires that the warehouse provides, as needed, raw materials for use in the production process....

Optimal Replenishment Policies for Multiechelon Inventory Problems Under Advance Demand Information

Customers and downstream supply chain partners often place, or can be induced to place, orders in advance of future requirements. We show how to optimally incorporate advance demand information into periodic-review, multiechelon, inventory systems in series. While the state space for series systems appears to be formidably large, we decompose the problem across locations, as in Clark and Scarf ...
