供应链单向及双向期权柔性契约比较分析

在随机市场需求环境下,对于易逝品供应链合作契约的数量柔性问题,建立了两种不同期权模式的柔性契约模型。通过对模型的求解与分析,得出了不同契约下销售商的订货策略,而且销售商在双向期权契约下比在单向看涨期权契约时的期权购买量要小,初始订货量要大,但总的预期订货量要小。销售商在两种期权契约模式下的总的最优订货量均大于传统订货方式下总的最优订货量。两种期权契约均可以提高销售商总的订货量,但在具体契约参数下,两者在接近供应链最优订货量上存在差异。

Comparison Analysis on Flexible Supply Contracts between Unilateral Options and Bidirectional Options

For the quantity flexibility contracts about perishable product's supply cooperation, we construct ted two models based on different options in stochastic market demand condition. By analysis, we gain retailers' order policies about different options. In the policies, retailers' option-order quantity is smaller, initial order is bigger, and total is smaller in the contract based on bidirectional options than in the contract based on unilateral options. The optimal total quantities in two different option contracts are bigger than the quantity in the traditional contract. The two option contracts can all improve retailers'total order quantity, but they are different their quantities approach the optimal supply chain order quantity in a given contract parameter.
