The deterioration of fossil fuels, as well as the issue of energy security crisis on the one hand, and the environmental problems caused by the consumption of fossil fuels on the other hand, have drawn global attention to the development and expansion of new energy as a clean and renewable energy source. Biomass is one of the most important known sources for clean energy production in the world. Because in addition to being renewable, it also has far fewer environmental effects. There is a wide range of biomass sources including edible and non-edible plants and grains, agricultural and forests residue, animal wastes, urban and industrial wastes, algae and microalgae, etc., which are classified in three generations. In this research, a model for designing an integrated network of gas oil and biodiesel supply chains with economic, environmental and social goals is presented. The economic objective function maximizes the net present value of profit, the environmental objective function minimizes the environmental pollution caused by carbon dioxide emissions and the social objective function maximizes positive social factors such as reducing unemployment, reducing migration to metropolitan areas, increasing Migration to border cities, increased employment. Also, due to the nature of some parameters, it is necessary to consider the uncertainties in mathematical modeling. Therefore, due to the important role of uncertainty in international relations in the field of fuel, the amounts of export demand have been considered as uncertain parameters and a two-stage random planning approach has been used. The mathematical model was solved using the augmented constraint method for Iran as a case study using GAMS software and the results were analyzed.
