A Queueing Model Analysis of a Hybrid Manufacturing/Remanufacturing System

Abstract

 

Refurbished item sale is becoming a common practice especially in electronics industry. This new source of revenue brings new problems as well, such as marketing, pricing and production planning for this new line of product. In this study, a firm that sells goods both in the new item and refurbished item markets is considered. The production and inventory system of the firm is modeled. We consider both no product substitution and partial product substitution cases. A queueing network is used to model the system and an algorithm to calculate the best base-stock inventory levels for both item types is presented. The results are used to discuss the implication of different production and quality strategies.
