Using a traditional leader-follower decisional sequence as the manifestation of power structure in a supply chain, this work generalizes extant research in IT security. We propose a game theoretic model to analyze the equilibrium IT security of the supply chain in the Stackelberg game, where the power structure in the supply chain manifests in a natural leader. Our results indicate that a natur...

I this paper, we investigate the equilibrium behavior of decentralized supply chains with competing retailers under demand uncertainty. We also design contractual arrangements between the parties that allow the decentralized chain to perform as well as a centralized one. We address these questions in the context of two-echelon supply chains with a single supplier servicing a network of (competi...

Supply chain formation is the process by which a set of producers within a network determine the subset of these producers able to form a chain to supply goods to one or more consumers at the lowest cost. This problem has been tackled in a number of ways, including auctions, negotiations, and argumentation-based approaches. In this paper we show how this problem can be cast as an optimization o...

Considering the impact of products’ eco-friendly level on demand, a two-stage closed-loop supply chain composed by a single manufacturer and a single retailer is constructed. Under both decentralized and centralized decision-making models, the paper deeply researches into the difference of supply chain system in economic benefits, environmental protection and social benefits, and a revenue shar...

This paper is considering the competition between two multi-echelon supply-chains on price and service under balance and imbalance of market power between the chains which are analyzing through Nash and Stackelberg game approach. The problem is categorized as the centralized or decentralized structure of each chain, which means a few different possible scenarios are developing based on the Nash...

Supply chains are networks of independent companies in a dynamic environment. The goal of supply chain management is the coordination of these companies in dynamic environment. This research addresses the decentralized coordination of independent operations planning in order to achieve near-optimal solution. Using a heuristic search with local optimization we coordinate two partners of a supply...

The ‘‘bullwhip’’ effect is a major cause of supply chain deficiencies. This phenomenon refers to grow the amplification of demand or inventory variability as it moves up the supply chain. Supply chain managers experience this variance amplification in both inventory levels and orders. Other side, dampening variance in orders may have a negative impact on customer service due to the increase in ...

Supply chain management is a crucial task of managing large organizations. In a decentralized supply chain each member focuses on maximizing his own profit. As a result of it, the conflict between the manufacturer and the retailers will arise. To avoid this sort of situations, coordination model strike a balancing between the profit of manufacturers and retailers. This paper investigates a two ...

The paper investigates interactions in a two-period closed-loop supply chain consisting of a single manufacturer and a single remanufacturer. In the context of recycling and remanufacturing by the remanufacturer, the manufacturer and remanufacturer choose different production strategies. By comparing the costs, profits and equilibrium quantity of supply chain members in decentralized and centra...

We consider a general multi-principal multi-agent contracting game in a complete-information supply-chain setting and determine coordinating equilibrium transfer schedules in closed form. The resulting contracts manage to align incentives for decentralized decision-making and achieve first-best channel solutions. We allow for multidimensional actions and arbitrary payoff externalities between a...
