契约博弈结合下农产品O2O二级供应链协调

An Interest Coordination of Double-channel Two-level Supply Chain for Fresh Agricultural Products under Contract Game

在由第三方电商平台-分销商组成O2O双渠道二级供应链中,将生鲜农产品新鲜度和信息对称性作为供应链利益协调的主要考虑因素,分别利用收益共享契约和博弈论的方法对电商平台和分销商的利益进行分配,找到两种分配方法的不足,最终建立基于收益共享契约的博弈论的分配方案,旨在增加供应链整体利益及其稳定性,更好地协调成员之间的利益。结果表明,利用博弈下的收益共享契约模型进行供应链利益协调可以更加全面地考虑影响因素,通过考虑新鲜度影响下双方成员的得失使其得到最佳的利益分配结果。通过算例分析可以得出,在集中决策下的隐瞒度为0.8时,双方的利益差距呈缩减趋势,显示出博弈论下收益共享契约模型较博弈模型下利益分配的优势。

In the two-channel supply chain consisting of a third-party e-commerce platform and distributors, fresh agricultural products and information symmetry are considered as the main factors to coordinate the interest of the supply chain. The benefits of the e-commerce platform and distributors are allocated by means of revenue-sharing contract and game theory respectively, and two kinds of allocation are found. Finally, a game theory allocation scheme based on revenue sharing contract is established to increase the overall benefit and stability of the supply chain and better coordinate the interests of members. The results show that the benefit-sharing contract model under game theory can consider the factors more comprehensively, and get the best benefit distribution result by considering the gain and loss of the members under the influence of freshness. Through the analysis of examples, it can be concluded that when concealment is 0.8 under centralized decision-making, the gap of interests between the two sides tends to decrease, which shows the advantage of profit sharing contract model under game theory over that under game model.
