Purpose. The purpose of the article is to develop a new unified procedure for planning of the fuzzy multi-product, dynamic and competitive flows in the transport networks and in the information network systems. The procedure is based on the use of the parallel synchronous algorithms for inhomogeneous maximum flows calculating. Methodology. The paper proposes the mathematical models’ classification of the tasks for planning the flows in transport networks. The possibilities of using the unified procedure and the parallel synchronous algorithm for calculating the maximum inhomogeneous flows for implementation of the tasks for planning multi-product, fuzzy, dynamic and competitive flows are investigated. The efficiency and universality of the proposed methods for the planning inhomogeneous flows is established by comparing the results of the calculations obtained in the article with the known results. Findings. The article proposes classification of the mathematical models for the planning inhomogeneous flows in the transport networks. The unified procedure and the parallel synchronous algorithm for planning fuzzy multi-product, dynamic and competitive flows in the transport networks have been developed. The tasks of the optimal distribution of the fuzzy multi-product, dynamic and competitive flows in the transport networks are realized. Originality. The article describes the new unified procedure for planning fuzzy multi-product, dynamic and competitive flows in the transport and information systems, using the parallel synchronous algorithms for calculating maximum flows. The procedure allows us to calculate the local extrema of the optimal flows distribution models. Practical value. The practical value of the obtained results is determined by the unified capabilities and the procedure efficiency, as well as the parallel synchronous algorithm designed to calculate the maximum multi-product flows in transport networks. The developed procedure provides the possibility to solve the analysis and planning problems of the multi-product flows in the networks for dynamic, fuzzy and competitive models for the distribution of the transport and information flows.
