Modelling of the waste flow in the Czech Republic

Strategic planning is the basis for efficient and sustainable waste management. Data collection and its deep understanding are essential for effective planning. Waste flows are an important information to assess waste management to date. This information has so far been available only aggregated at national level in the Czech Republic. In this thesis, an approach has been developed to reconstruct the waste flows at a sub-national level from available data. The approach consists of two optimization models: partial and final. The partial model is based on expert assumptions. The reconstruction of the flows by the partial model is done sequentially in smaller groups of flows. The computation of the partial model is repeated with different composition of the groups of flows optimized at the same time. Each iteration results in a~candidate solution which is used as an input data for the final model. The solution of the final model yields the final reconstruction of the waste flows. Model development and testing was carried out on problems simulated based on the real data from the waste management of the Czech Republic
