Supply Chain Decision-Making Strategy Research Under Supply Chain Parameters Risk Fluctuating

Nowadays the subject of supply chain management has won more attention of the researchers due to the development of globalization. As an effective solution to coordinate supply chain, supply chain contracts play an important role in supply chain management. However, as there is an increase in the influence which the supply chain risks bring to the enterprise environment, both internal and external, how it will effect on the supply chain contracts can't be ignored.Based on the analysis of the classical buy-back contract and the classical revenue-sharing contract, this article further discusses the retailers'order strategies when suppliers are able to modulate the contracts'parameters during the risk fluctuations. Moreover, this paper conducts research on two kinds of risk fluctuations:risk fluctuations in buy-back contract's price and risk fluctuations in revenue-sharing rate of revenue-sharing contract respectively. Several mathematical models are proposed to maximize the supply chain's revenue through determining optimal order quantity when taking both contract risk fluctuations into account, and also discuss the impacts on the retailer's revenue and the revenue of entire supply chain.Under some conditions, transitional buy-back contract equals to revenue-sharing contract, so another achievement of this paper tells whether the same relationship exiting between two kinds of contacts with risk fluctuations, and determines which is the optimal contact for retailer to choose. As a result, if two kinds of risk fluctuations follow the same probability distribution, expected revenue could be saved effectively when retailer chooses buy-back contract.When the supply chain contacts'parameters risk fluctuating, yet Retailers have no adjustment in their order quantity, resulting changes in expected revenue from each entity involved in supply chain. Chapter five puts research on how to make a decision of contact for retailer without considering two kinds of contact parameters. Some results are listed as follows:if the risk of buy-back contract and revenue-sharing contract fluctuates, retailer's revenue and the revenue of supply chain suffer, while the supplier's revenue increases. If there are risk fluctuations in contact parameters, the expected revenue of entire supply chain equals to two kinds of transitional contacts, however, the revenue that retailer losses will transfer to the supplier side, which generating revenue decreasing. If retail doesn't realize the supply chain contact has risk fluctuations, the buy-back contract will be the best option to save the losing revenue.This paper offers solution to retailer by designing a decision-making software package. This package takes good advantages of MATLAB tools, providing a User interface through GUI design methods of MATLAB, which could give data support when retailer makes decision.
