Originální abstrakt

The following paper is devoted to the construction of new waste-to-energy plants in a territory where is already another fossil-fuel power station built. The aim is to create a mathematical model and show that those two devices are able to cooperate effectively. The related mathematical programs are developed, linked, and implemented in GAMS. For computational purposes a specific heuristic that optimizes unknown approximated profit function relating IRR and plant capacity is considered. The built models focus on operational policies and can be characterised as non-linear integer programs. The optimization software GAMS is used for their calculation. Because of the model complexity the solution process starting in a certain initial point may end in a local optima or not found any at all. So, the paper also focuses on the elimination of nonlinear terms by using binary variables in such a way that the transformed optimization program can be solved within acceptable time limits and the suboptimal solution is reached.
