A Fuzzy Inventory Model for Vendor – Buyer Coordination in a Two Stage Supply Chain with Allowed Shortages

چکیده
This paper develops Fuzzy inventory model to determine the relevant profit maximizing decision variable values. The model proposed is based on individual profits of vendor and buyer and joint total profit of them which finds out optimal ordering quantity, selling price and shipment policies. Shortages are allowed for both of them. Production rate, ordering quantity, shortage and holding cost of buyer and vendor are taken as triangular fuzzy numbers. Graded mean integration representation method is used for defuzzification. The conclusion drawn from Numerical example is, it is more beneficial for the buyer and vendor to co-operate with each other when the demand is more selling price sensitive.

An Integrated Production-Inventory Model with Backorder and Lot for Lot Policy
inventory model, backorder buyer , vendor, lot for lot policy In this paper, an inventory model for two-stage supply chain is investigated. A supply chain with single vendor and single buyer is considered. We assume that shortage as a backorder is allowed for the buyer and the vendor makes the production set up every time the buyer places an order and supplies on a lot for lot basis...

Lead time is one of the major limits that affect planning at every stage of the supply chain system. In this paper, we study a continuous review inventory model. This paper investigates the ordering cost reductions are dependent on lead time. This study addressed two-echelon supply chain problem consisting of a single vendor and a single buyer. The main contribution of this study is that the in...

This paper formulates a two-echelon single-producer multi-buyer supply chain model, while a single product is produced and transported to the buyers by the producer. The producer and the buyers apply vendor-managed inventory mode of operation. It is assumed that the producer applies economic production quantity policy, which implies a constant production rate at the producer. The operational pa...

متن کاملAn Inventory Model for Solving Two Stage Supply Chain using Fuzzy Costs with Shortage
A fuzzy inventory model is proposed to maximize the profit in a two stage supply chain model. In this paper joint total profit of both buyer and vendor are calculated. Shortage for the buyer is allowed and it is completely backlogged. Number of shipments, selling price and order quantity are taken as decision variables. Graded mean integration representation method is applied for defuzzificatio...
