This paper develops an analytical model that explores how important supply chain parameters affect the cost savings to be realized from collaborative initiatives such as vendor-managed inventory (VMI). Results from the model show that benefits, in the form of inventory cost reductions, may be generated from integration depending upon the ratio of the order costs of the supplier to the buyer and...

In this paper, production-inventory models for a deteriorating item in a single vendor-buyer system has been developed with constant production and demand rate. Shortages at the buyer (when it is allowed) depends on time. The models have been formulated as cost minimization problem via both integrated and non-integrated approaches and solved using genetic algorithms developed to solve the singl...

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...

Supply chain management is an integrative approach for planning and control of materials and information flows with suppliers and customers as well as between different functions within a company. One particularly important element in supply chain management is the management of inventories. This field has received considerable attention during the last years. Nevertheless, most quantitative an...

A supply Chain (SC) with single vendor and single buyer is considered. In this research is presents lead time reduction system in an integrated inventory model for non-defective items in order to minimizing the sum of the ordering cost/setup cost, holding cost, transportation cost, production cost and lead time crashing cost of simultaneously optimizing the optimal order quantity, lead time and...

A vendor has several secrets which he regards as of equal worth and importance. He is willing to sell any of these secrets to a buyer. The bargain is said to be secure when the following two conditions are satisfied: 1) the buyer can only obtain one secret if he pays for only one secret, and 2) the vendor will not be able to find out which secret the buyer picked. This cryptographic problem is ...

Huang (2010) [1] proposed an integrated inventory model with trade credit financing in which the vendor decides its production lot size while the buyer determines its expenditure tominimize the annual integrated total cost for both the vendor and the buyer. In this paper, we extend his integrated supply chain model to reflect the following four facts: (1) generated sales revenue is deposited in...

Selection and negotiation of purchasing bids is a complex decision making process that requires consideration of a variety of vendor attributes such as price, delivery performance, and quality. Although several decision models have been utilized for vendor evaluation and selection, this paper proposes a buyer–seller game model that has distinct advantages over existing methods for bid selection...

Abstract Loyalty programs allow vendors to profile buyers based on their purchase histories, which can reveal privacy sensitive information. Existing privacy-friendly loyalty force choose whether purchases are linkable. Moreover, receive more data than required for the sake of profiling. We propose a privacy-preserving program where always unlinkable, yet vendor buyer her history, remains hidde...
