Developing globalization and increasing competition have forced supply chain members to continuously decrease their operational costs. Coordination between different business entities in a supply chain is considered as an important way to gain competitive advantages and obtain savings in the total system. One of these coordination mechanisms is known as joint economic lot sizing; where production, inventory, ordering and shipment policies are synchronized simultaneously between all members. In this paper, a comprehensive and up-to-date review of the joint economic lot sizing (JELS) model is presented. At first, we discuss different shipment policies and then we review papers in ten other dimensions of the problem, including quality, investment in setup and order cost reduction, controllable lead-times, deterioration, three-stage supply chains and so on. Moreover, four main directions for future research into this important problem are proposed.
