The application of flow networks on the example of the types of works distribution as well as the distribution of construction workers qualification structure according to particular types of buildings is presented in the paper. The flow networks considered were proposed by Zdzislaw Pawlak and are the tools for the new mathematical models related to the information regarding flow explorations in decision algorithms. The decision algorithms consist of series of decision rules for each particular case of various types of construction objects interdependence, as well as of various kinds of workers and their qualification structure. It is all generated in the paper.
