Tkachenko V. Information technology of decision-making support in case of transboundary emergencies

In the process of decision-making in case of emergencies, the following stages are distinguished: monitoring of the environment state; organizing of subsystems interaction as the operational deployment of information infrastructure; collection and processing of data for making operational decisions; liquidation of emergency consequences. The conceptual model is proposed as a basis for solving the environmental monitoring problem. The conceptual model formalizes the interaction between data sources, methods and means of data collection and environmental indicators. The ecological system is considered as a complex object, the state of which cannot be estimated explicitly. Therefore, it is proposed to estimate of ecological system state based on the observed parameters. One-parametric or many-parametric estimation models are used for ecological system state estimation. One dimensional logistic model for measuring the level of ecological safety has been developed. It has allowed determining the emergency case in real time and reducing the time for operational response. The application of the deformed configurations method reduces the time of obtaining data to clarify the state of environmental safety. In the thesis, the methodical bases of creating information and analytical maintenance for decision support in the conditions of transboundary emergencies are developed. The typical model of the decision-making problem in the emergencies is developed, and the ontological specification of knowledge representation has been developed. It allowed constructing the intellectual system core and provide data processing in the search processes and analysis of precedents. The technology of cooperation in case of emergencies consists of the following steps: the definition of emergency classification features, the organizational structure formation of the emergency response staff, the information infrastructure organizing and the preparation of operational reports. The model of multi-sign classification is proposed by the application of the algebra-predicate approach to the formalization of environmental information processes. The method of constructing a flexible information infrastructure is developed to support decision-making in case of transboundary emergencies. The method of constructing a flexible information infrastructure applies the concept of "information as a service" and the device meta-model. This allowed reducing the deployment time of the information system and increasing the efficiency of information and analytical decision support systems in case of emergencies and the elimination of the emergency consequences.
