The thesis deals with the coordination of product flows in the retail supply chain. Supply chains operate in a constantly changing environment and strongly depend on consumer demands. A typical retail supply chain consists of several stores that are supplied from at least one retailer's warehouse. In order to achieve consistent supplies between supply chain facilities, it is urgent to first achieve a proper coordination of the interrelated activities. When defining a mathematical model, our first focus was on future demand satisfaction, whereas pricing policies, perishability and other factors will be addressed by further research on the complementary model for the operative planning. The idea is to first obtain a preferable distribution plan (tactical plan) with minimal expected distribution costs and minimal expected supply risks. The problem is presented as a multi-objective optimization problem, for which we propose the stochastic model that combines several methods and procedures, including graph theory, probability theory and operational research. As the selected problem is computationally hard to solve, we use local search heuristics and propose a robust optimization solution approach. The experimental study shows that for the optimization problem we can implement an algorithm that provides useful solutions.
