Growing ecological concerns has led governments to utilize mechanisms such as Renewable Identification Number (RIN) in promoting biofuels as an alternative for fossil fuels. In this paper, a pricing model in a decentralized three-player biofuel supply chain with RIN mechanism is proposed and the interaction among members is analyzed using Stackelberg game. The optimal selling price of biomass, bioethanol, and RIN are obtained by solving the proposed discrete mathematical program with equilibrium constraints (DC-MPEC) problem which is transformed into a solvable mixed integer quadratic programming (MIQP) model. Finally, a real case study in Iran is presented to show the features of the model. Sensitivity analyses are performed which lead to some managerial insights into the effect of price elasticity and government policies on profits. Moreover, an evolutionary game theory approach is applied on the case study to show the long-term behavior of the members in the proposed RIN-based pricing model.

日益增长的生态问题促使政府利用诸如可再生识别码（RIN）之类的机制来促进生物燃料作为化石燃料的替代品。提出了一种具有RIN机制的分散式三人生物燃料供应链定价模型，并通过Stackelberg博弈分析了成员之间的互动关系。通过解决所提出的带有平衡约束的离散数学程序（DC-MPEC）问题，获得了生物质，生物乙醇和RIN的最优售价，并将其转化为可解决的混合整数二次规划（MIQP）模型。最后，在伊朗进行了一个实际案例研究，以显示该模型的特征。进行了敏感性分析，从而引起了一些管理人员对价格弹性和政府政策对利润的影响的见解。此外，
