Development of a Consignment Inventory Model in a Two- echelon Supply Chain with Backorder
نویسندگان
چکیده
This paper considers a two-level supply chain consisting of a manufacturer and two buyers. The manufacturer produces one type of products at a finite rate and replenishes them to the buyers. Each buyer’s demand is sensitive to his selling price and the backorder is allowed at the buyers. Moreover, it is assumed that the buyers delay paying for goods to the manufacturer and two types of delay in payment are considered; delay paying for the purchased items till they are used or sold to the end customers, and delay paying till the next replenishment order. The main aim of this research is formulating the manufacturer and the buyers’ problems in terms of integer-ratio policy and discounted cash flow under these two types of delay in payment. Keywords— Consignment inventory, delay in payment, discounted cash flow, trade credit, two-echelon supply chain.

متن کاملStochastic Inventory Systems in a Supply Chain with Asymmetric Information: Cycle Stocks, Safety Stocks, and Consignment Stock
The two critical factors distinguishing inventory management in a multifirm supply-chain context from the more traditional centrally planned perspective are incentive conflicts and information asymmetries. We study the well-known order quantity/reorder point (Q r) model in a two-player context, using a framework inspired by observations during a case study. We show how traditional allocations o...

In this paper, we apply continuous review (S-1, S) policy for inventory control in a three-echelon supply chain (SC) including r identical retailers, a central warehouse with limited storage space, and two independent manufacturing plants which offer two kinds of product to the customer. The warehouse of the model follows (M/M/1) queue model where customer demands follow a Poisson probabilit...
