Sharif University of Technology Sharif Journal of Industrial Engineering & Management 2676-4741 26 2 2010 11 22 A MULTI-ITEM VENDOR-MANAGED INVENTORY WITH JOINT ORDERING CONSTRAINT A MULTI-ITEM VENDOR-MANAGED INVENTORY WITH JOINT ORDERING CONSTRAINT 9 14 5174 FA M. Amiri Accounting & Management, Allameh Tabatabaei University Journal Article 2009 01 12 This paper investigates a two-echelon single-vendor multiple-buyers supply chain model. This model formulates an under Vendor Managed Inventory (VMI) mode of operation, in order to maximizing the profit of the supply chain, based on optimizing the length of the buyer ordering period; the relationship between the demand of buyers and the sales price is also considered linearly. In this paper, for the first time, a two-echelon single-vendor multiple-buyers supply chain model is considered under multi-item and joint ordering assumptions. Also, analysis of the model is carried out with a numerical study. Furthermore, the numerical example is solved using the LINGO tool, and the sensitivity of the model, with the number of buyers and the constant ordering cost, is investigated.
