Abstract: The introduction of high-quality agricultural products traceability system can improve effective supply, shorten the circulation time, and reduce the wastage of quantity and value loss in the circulation, which leads to a series decision problems of the dual channel supply chain system in the aspects of investment, marketing, pricing and others. In this paper, the quality fresh agricultural products manufacturers open up electronic channels, in view of the fact that the traceability system could reduce the circulation losses and improve the quality, and the decision-making models of dual channel supply chain led by the manufacturers are constructed respectively. This present paper focuses on the comparative analysis of the optimal strategies of supply chain members on the investment, pricing and channel sales before and after the application, then obtains the core boundary values related to the optimal decision. The results combined with numerical simulation show that: the core boundary values are mainly related to the degree of improvement of double loss and involved parameters, the acceptable costs of members and system of supply chain to accept the traceability system are different, and the application cost has different influences on the sales volume of each channel. But the cost boundary values of price adjusted by each member are consistent.

Key words: high-quality fresh agricultural products, dual-channel supply chain, circulation wastage, the application cost, core boundary value

摘要： 优质农产品溯源系统的引入,既能提升有效供给、缩短流通时间,又能降低流通中的数量损耗和价值损失,由此带来了双渠道供应链系统在投资、销售、定价等方面的系列决策问题。考虑制造商开辟电子渠道、从溯源系统降低流通损耗和提高质量出发,分别构建制造商主导型的双渠道供应链决策模型。通过对比分析应用前后各成员在投资、定价及销售方面的最优策略,得到相关的核心边界值。数值仿真结果表明:核心边界值主要与双重损耗的改善程度及其他参数相关,各成员及系统接受溯源系统的应用成本不同,应用成本对各渠道销量的影响程度亦不相同,但各成员调整定价的应用成本边界值是一致的。
