Development of Theoretical Foundations: A Set of Methods and Algorithms for Substantiating Decision-Making by a Management Organization in an Infrastructure-Complex Territory in the Interest of Reducing the Risk of the Possibility of Cascading Accidents Escalating into Intersystem Accidents

A new direction in the system analysis and decision making of the occurrence of cascade accidents escalating into intersystem accidents is successfully developing in the world. The aim of the article is to develop theoretical foundations, methods and algorithms to justify the most adequate decision-making by one of several independent managing organizations at the same time to manage the risk of cascading and intersystem accidents. Existing methodological approaches to risk analysis do not allow to fully solve the problems of substantiating a number of managerial decisions. For example, in the sphere of organizing the activities of managing organizations, it is important to justify the criteria and target levels of indicative indicators, to forecast the effectiveness and efficiency of activities using risk criteria.
