This paper studies a periodic-review, serial supply chain in which materials are ordered and shipped according to (R,nQ) policies. Three information scenarios are considered, depending on the level of information available: echelon, local, and quasilocal. In the echelon scenario, each stage can access the inventory and cost information within its echelon (comprising the stage itself and all downstream stages); in the local scenario, each stage only accesses its own local information. Finally, in the quasilocal scenario, each stage knows its local information, plus the actual customer demands. We propose coordination schemes that regulate the stages to achieve the supply chain's optimal cost under each information setting. All these coordination schemes fit comfortably within an emerging practice called supply chain finance, which includes the organization and technology needed to implement them.
Flexibility value of enterprise's logistics capability is one of the key factors which influence the quick response to customers in decentralized supply chain.This article analyzed the characteristics of enterprise's logistics capability in decentralized supply chain,defined the flexibility of enterprise's logistics capability and its value,and analyzed the way of calculating the uncertain investment benefits.Then we constructed the model of flexibility value of enterprise's logistics capability based on multistage stochastic mix integer programming and real option through investment.The surpassing sample technology of Latin super cube and Monte Carlo were put forward to solve this problem.This model solved the problem that anomalous value calculation of logistics capability investment was ignored by traditional finance method.Finally a case explained that this model was effective on calculating flexibility value of enterprise's logistics capability.
The paper considers a three-tier credit chain consisting of a bank, a logistic company and a retailer. The paper analysis the following outsourcing structure implemented by top-tier bank: inhouse consignment, under which the bank signs independent contracts with the logistic company and the retailer. Under the assumption that the logistic company cannot change its decision, the paper investigates the equilibrium behavior of the decentralized credit chain with non-cooperation newsvendor under demand uncertainty. The model includes the case of a risk-neutral bank offering loan to a noncooperative risk-neutral retailer who mortgages its inventory to the bank to finance more inventory. The retailer faces a random demand in a single sales season as in the classical newsvendor problem. By game theorem, the paper gives the optimal loan to value to retailers with different initial capital.

The purpose of this paper is to propose a new approach for the supply chain management. This approach is based on the virtual enterprise paradigm and the used of multi-agent concept. Each entity (like enterprise) is autonomous and must perform local and global goals in relation with its environment. The base component of our approach is a Virtual Enterprise Node (VEN). The supply chain is viewed as a set of tiers (corresponding to the levels of production), in which each partner of the supply chain (VEN) is in relation with several customers and suppliers. Each VEN belongs to one tier. The main customer gives global objectives (quantity, cost and delay) to the supply chain. The Mediator Agent (MA) is in charge to manage the supply chain in order to respect those objectives as global level. Those objectives are taking over to Negotiator Agent at the tier level (NAT). These two agents are only active if a perturbation occurs; otherwise information flows are only exchange between VENs. This architecture allows supply chains management which is completely transparent seen from simple enterprise of the supply chain. The used of Multi-Agent System (MAS) allows physical distribution of the decisional system. Moreover, the hierarchical organizational structure with a decentralized control guaranties, in the same time, the autonomy of each entity and the whole flexibility.
