TKatsman M.D. Methodological basis of the environmental safety management during the liquidation consenquences of emetgency situations in railway transport. – Qualification scientific work as a manuscript. The thesis for the degree of doctor of technical sciences, specialty 21.06.01 – ecological safety. – National Aviation University, Kyiv, 2018. The thesis presents overview of world experience and authors own theoretical and experimental researches, the actual scientific and practical problem of reducing the harmful effects on the environment and human life of negative factors of emergency situations during transportation of dangerous goods by railway. To manage such emergency situations improved decision making system it is proposed. The thesis presents the results of research and modeling of the impact of the consequences of ecologically dangerous railway emergency situations on the environment and human activity, as well as processes of managing the actions of liquidation units on the basis of information technology of network center management. Analytical and experimentally grounded mathematical models of propagation of pollutants in the atmosphere as a result of railway emergency situations with flammable goods are presented. The system of railway transportation in the event of emergencies is formalized, depending on the effectiveness of responding to such situations, on the basis of which mathematical models are developed to determine the probability of the states and the level of environmental safety of this system. It is proved that the effectiveness of the response to environmentally hazardous rail situations with dangerous goods increases with the use of the appropriate decision making system, for the creation of which the mathematical models for the development of such situations and operational algorithms of the head of the operational headquarters are proposed, as well as mathematical models for determining the effectiveness of the actions of the liquidation units and their compounds. It is proved that the capabilities of the railway functional subsystem "The forces and means of responding to emergencies on the railway transport" can be greatly increased by managing them from situational centers based on the network-centric principle of managing complex hierarchical ergatic systems. Key words: ecological danger, railway emergency situation, environment, decision making, information technology, decision support system, network center management.
