Diploma paper is dealing with complex analysis of the information and material flows in concrete mixtures production focusing on proposals of logistic cost optimalization. The complex analysis is based on the time and direct observation in selected subject. One part of this work is dealing with optimalization of supply of production raw materials especially self supply of gravel aggregate into the each concrete mixing plant. Second part of this work is dealing with selected subject fleet optimalization. Optimalization possibilities were based on the results of the comprehensive analysis of the information and material flows.
