In the course of globalization, many enterprises change their strategies and are coupled in partnerships with suppliers, subcontractors and customers. This coupling forms supply chains comprising several geographically distributed production facilities. Production planning in a supply chain is a complicated and difficult task, as it has to be optimal both for the local manufacturing units and f...

To analyze effects of supply chain coordination for deteriorating goods with stock-dependent demand rate, this paper presents decision models for order quantity and ordering cycle under two scenarios( decentralized supply chain, centralized supply chain). Numerical study is carried out to demonstrate the effectiveness of the proposed models, and to analyze the impact of supply chain coordinatio...

This paper develops a decentralized leader-follower game for network design of a competitive supply chain problem in which a new chain as the leader enters a market with one existing supply chain as a follower. Both chains produce an identical product, customer demand is inelastic and customer utility function is based on Huff gravity-based model. The leader wants to shape his network and set a...

Under the assumptions of complete sharing information between organizational departments and presence an independent decision making authority for entire supply chain, previous chain research highlights centrally controlled models. Due to privacy, most facilities in are functionally centralized exercise. Collaboration these functional units is important responding rapid changes customer require...

Supply Chain Formation is the process of determining the participants in a supply chain, who will exchange what with whom, and the terms of the exchanges. Decentralized supply chain formation appears as a highly intricate task because agents only possess local information, have limited knowledge about the capabilities of other agents, and prefer to preserve privacy. State-of-the-art decentraliz...

Supply Chain Formation involves determining the participants and the exchange of goods within a production network. Today’s companies operate autonomously, making local decisions, and coordinating with other companies to buy and sell goods along their Supply Chains. Such temporal interactions need to be formed rapidly and in a decentralized manner. For sufficiently large problems, current state...

This work explores the impact of quick response on supply chain performance for various supply chain structures with strategic customer behavior. By investigating pricing and inventory decisions in decentralized supply chains under revenue-sharing contracts and in centralized supply chains, we study the performance of four various systems and compare the value of quick response in different sup...

This paper studies four substitutable products in a two level supply chain which consists of two suppliers and two manufacturers. We develop two competitive models that decisions are made on the decentralized and centralized decisions respectively. Then we get the optimal pricing for four products in each condition. Through detail numerical analyses, we discuss the price, product demand and the...

This paper considers a two stages pharmaceutical supply chain (PSC) consisting of a pharmaceutical manufacturer (pharma-manufacturer) that supplies one type of pharmaceutical product to a pharma-retailer. The customer demand rate for the pharmaceutical product is dependent on the pharma-retailer’s current-inventory level. The pharma-retailer determines the order quantity ( ) value as decision v...
