An Inventory Model for Obsolescence Items with Consideration of Permissible Delay in Payments (Case Study of Obsolete Medicines in Pharmacies)
Background and Objectives: In the real world, the obsolescence items are some items that lose their value over time due to the emergence of new technology. Because of rapid changes in technology, inventory management of such items is considered in recent years. Moreover, suppliers try to encourage the retailers for purchasing an item before it is outmoded with some policies suc...
متن کاملDetermining Optimum Redesign Plans for Avionics Based on Electronic Part Obsolescence Forecasts
Many electronic parts have life cycles that are shorter than the life cycle of the product they are in. Life cycle mismatches caused by the obsolescence of electronic parts can result in significantly sustainment costs for long life systems. In particular, avionics often encounters part obsolescence problems before being fielded and nearly always experience part obsolescence problems during the...
متن کاملA periodic-review inventory model with application to the continuous-review obsolescence problem
In this paper we consider a stochastic-demand periodic-review inventory model with sudden obsolescence. We characterize the structure of the optimal policy and propose a dynamic programming algorithm for computing its parameters. We then utilize this algorithm to approximate the solution to the continuous-review sudden obsolescence problem with general obsolescence distribution. We prove conver...
متن کاملObsolescence Driven Design Refresh Planning for Sustainment- Dominated Systems
Many technologies have lifecycles that are shorter than the lifecycle of the product they are in. Lifecycle mismatches caused by the obsolescence of technology (and particularly the obsolescence of electronic parts) results in high sustainment costs for long field life systems, e.g., avionics and military systems. This paper presents a methodology for performing optimum design refresh planning ...
متن کاملOptimal Control of an Inventory with Simultaneous Obsolescence
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...
متن کاملTechnology adoption under embodiment: A two-stage optimal control approach∗
We use two stage optimal control techniques to solve some adoption problems under embodied technical change. We first solve a benchmark problem without learning behavior. At the date of switching, the consumption level is shown to drop, as the relative price of capital goes down (obsolescence). In such a case, the economy sticks to the initial technology, or immediately switches to a new techno...
