The article is devoted to the elaborating a simulation model of the crisis processes development in the real sector of the economy of Ukraine on the basis of using system dynamics concept. The model contains five submodels simulating crisis development processes in agriculture, production of petroleum products, machinery, metallurgy, food industry, and also time series trends for some other branches. The interaction of different sectors is modeled by input-output model. There is demonstrated the role of external shocks in crisis phenomena development in each of the industries and their distribution in the feedback loops.
