ADVANCE DEMAND INFORMATION IN PRODUCTION/INVENTORY SYSTEMS

This paper is a research review, which discusses the impact of using advance demand information on the performance of production/inventory and inventory systems. The aim of this study is to evaluate the benefits of demand information sharing, to identify the current research gaps and to study the future trend in this field. Different types of advance demand information and their potential benefits in production and inventory systems are reviewed. We consider a context where the customers (final clients, assembly lines….) share demand orders in advance of their due dates. We called this type of information, advance demand information (ADI). ADI models can be divided on two classes: Perfect and Imperfect ADI. Imperfect ADI, the supplier has reliable information about the customer demand, so the placed orders cannot be revised. In imperfect ADI, the information is uncertain and can change in any moment. In this study, we focus on the case of perfect advance information and more specifically on the amount of certain advance demand
