| A supply chain is a network system which consists of several independent members focusing on the production and sales of one or more products. Nowadays, with the development of economic globalization, the competition on marketing is becoming a competition among different supply chains, instead of an activity merely among enterprises. However there exist too many X-factors preventing the efficient allocation of available resources, causing a low supply chain efficiency. Only with the support of certain technology and coordination mechanism can a supply chain system be well coordinated. As for a supply chain of one supplier and one retailer, members'irrational decision making and double marginalization are two main causes that undermine the chain's coordination, and a proper contract is an efficient solution to the problem.Researches existed in supply chain coordination mainly focus on products with a mature market which is rich in demand information, however its model and approach can not properly work under a new product circumstance.Our aim is to investigate the coordination feature of new products supply chain, and to seek proper ordering decision making for the retailer and buy back policy for the supplier, hence basic knowledge of supply chain coordination, supply chain contracts, and ordering decision making with partial demand information is reviewed, and with a one-supplier-one-retailer supply chain of certain new products, two models with partial demand information are constructed, one of which consists of a risk neutral supplier and a risk averse retailer, while members of the other model are both risk averse. Besides, the effect of traditional buy back policy on new product supply chain is studied, indicating that traditional buy back policy can't coordinate the chain in the first model, yet does coordinate the one in the second model under certain circumstances. This result is expected to help the decision-making of new products supply chain members. |
