A mixed integer non-linear programming model for tactical value chain optimization of a wood biomass power plant

► Developed a mathematical model to optimize the supply chain of a forest biomass power plant. ► Considered supply, storage, production and ash management. ► The model provided more profit compared to the actual profit of the company. ► Biomass purchase cost had the highest share in total cost. ► Investing in a new ash recovery system has environmental and economic benefits.
