定价和补货决策不再是组织内部的问题，从供应链(SC)的角度协调这些主要决策具有重要意义。在这项研究中，我们首次提出了一种基于信用期权的方法来协调价格敏感随机需求下制造商-采购链的生产、定价和定期评审决策。在所研究的供应链中，采购商采用定期复查订货至最高库存策略，其决策变量为最高订货水平、销售价格和复查周期。在这种情况下，制造商遵循经济生产量(EPQ)政策，并决定生产乘数。首先，提出了在集中式和分散式结构中寻找最优决策的精确算法和凹性分析。然后，提出了信用期权机制，以获得双方都能接受的决策，创造了制造商和买家的双赢局面。通过数值算例和灵敏度分析，并结合实际案例分析，说明了信用期权合约的适用性和有效性。结果表明，所提出的信用期权合同能够协调定价、生产和定期审查补货决策，从而鼓励双方接受协调机制。此外，研究结果还表明，在某些情况下，所提出的信用期权合同甚至比集中式合同更能提高供应链利润。
Pricing and replenishment decisions are no longer internal issues within organizations and it is of high significance to coordinate such primary decisions from a supply chain (SC) perspective. In this study, for the first time, we develop a new method based on credit option to coordinate production, pricing, and periodic review policy decisions considering a manufacturer-buyer chain under price-sensitive stochastic demand. In the studied SC, the buyer applies a periodic review order-up-to level inventory policy and its decision variables are order-up-to level, selling price and review period. In this case, the manufacturer follows an economic production quantity (EPQ) policy and decides on production multiplier. Firstly, exact algorithms in addition to concavity analysis are addressed to find optimal decisions in centralized and decentralized structures. Afterwards, a credit option mechanism is proposed to obtain mutually acceptable decisions and create a win–win situation for the manufacturer and buyer. Numerical examples and sensitivity analysis along with a real case study are carried out to show the applicability and performance of the credit option contract. The results reveal the capability of the proposed credit option contract in coordinating pricing, production, and periodic review replenishment decisions; thereby encouraging both sides to accept the coordination mechanism. Moreover, the results indicate that the proposed credit option contract can even improve the SC profit more than centralized model under some circumstances.
