طراحی قرارداد هماهنگی برای زنجیره تامین سوخت زیستی در چین

To ensure the sustainable supply of agricultural feedstock for biofuel production and improve the performance of biofuel supply chain, coordination along the biofuel supply chain in a random yield environment is studied. Three types of coordination contract are examined, namely, an over-production risk-sharing contract (OPC), an under-production risk-sharing contract (UPC), and a mixed contract (MC) with an asymmetric Nash bargaining model. Though an OPC and a UPC can correct the farmers’ over-production and under-production behavior, the expected increase in profit may not be realized by the biofuel producer or the farmers. The MC is feasible because it achieves an efficient supply chain, where supply chain optimization as well as the interests of all individual actors are respected simultaneously. The proposed contracts are tested with data from the cassava-based biofuel industry in China. The findings help practitioners and policy makers understand when and how to implement coordination contracts to achieve the sustainable supply of agricultural feedstock for biofuel production and supply chain Pareto improvement as well.
