The synergistic features of the transport space are considered as sources, the resources of which are directed to the development of the system for ensuring the safety of the components of the chain: «the emergence of the need for products - the provision of transport services - production - the qualitative and quantitative level of mastering by consumers of cargo flows in the conditions of the existing limitations of the geographical space of industrial zones». The basic components of the chain are: the supplier, the manufacturer and the transport company. The state of the system was considered according to the Kurno equilibrium criterion. The synergistic effect of the system in the conditions of the existing spectrum of restrictions characteristic of the environment of the industrial zone, which arises during the integration of its components into a single security architecture, is determined.
This paper reports a comparative analysis of the known methods for reducing open transportation problems to a balanced form in order to further optimize freight traffic based on them. A series of significant shortcomings have been revealed that largely narrow the scope of their application. A new method has been proposed, termed the method of proportional redistribution of cargo transportation volumes among participants in the transportation process, devoid of the identified shortcomings. The transportation problem is a special case of the general linear programming problem, to which one of the methods for solving it, namely the simplex one, can be applied. A procedure to construct a simplex table based on the data from the transport table has been described, as well as the algorithm of subsequent simplex transformations. A transportation problem is often stated in the form of a map of the location of transport hubs of cargo dispatch and destination. A matrix-network model has been proposed, which makes it possible to reduce the network representation to a matrix form with the subsequent finding of the optimal plan for cargo transportation. In order to identify the priority of methods for reducing open transportation problems to a balanced form, 100 transportation problems that are unbalanced in terms of the volume of cargo transportation were solved. That was done with the help of a designed decision support system for the management of freight transport. As a criterion, the best freight transportation plan was chosen. As a result, the simplex method proved the best in 48 cases, the coefficient method ‒ in 27, the dummy node method ‒ in 16, and the difference method ‒ in 9 cases. The use of a decision support system for the management of freight transport has increased its efficiency by an average of 25 %
