It is a necessity to use more renewable resources to produce clean energy. The purpose of this research is to design a biomass supply chain network model. It is three-level with two minimization functions in economic and bio-environmental costs. The main research gap solved in this study is the resilience of the model, which examines the disruption in the supply of raw materials with a scenario approach. The mathematical model of the research is mixed integer linear programming. To single-target the function, under uncertainty, the fuzzy TH mathematical model has been used and the validation of the model has been investigated in a real case study in Tehran province. According to the findings from the output of GEMS software, which shows the optimal economic cost equal to 791354423200 Tomans and the emission of 1420469 grams of carbon dioxide per year, the optimal mode of construction of 4 power plants in the cities of Pakdasht, Qarchak, Parand and Mallard has been proposed. The sensitivity analysis on the parameters of the TH method and on the change of biomass supply values met the expectations. As a result, the proposed model has the necessary efficiency and has been able to be optimal in terms of cost and reduce greenhouse gas emissions by combining economic and environmental approaches. Therefore, the model has the necessary resilience.

Despite the decrease in the share of oil in the world's energy basket, the absolute amount of oil consumption is still increasing. Oil is at the center of the economic and political developments and countries with the oil and gas deposits are trying to maximize their benefit from these reserves. In Iran, there have been many policies and legislations related to optimizing the value and volume of the oil and gas reserve. The term "conservation production" has been mentioned several times in several legislations and guidelines however, it is still ambiguous as to how to implement this framework. This research has sought to use the real data of an oil reservoir (with periods of natural depletion, primary production, secondary and tertiary recovery), different objective functions (reservoir net present value and final recovery factor), and the effect of changes in the optimization period to model the concept of conservation production. The results show that the changes in the objective function and the optimization periods would have a significant effect on the production path.
