The transition from empirical assessments to scientifically based methods of making environmentally sound decisions lies through the creation of expert environmental monitoring systems focused on assessing and predicting the state of the environment under anthropogenic impact. The natural environment (NSE) is considered as an open dynamic system. The phase space of a dynamical system is characterized by the state space considered as a point in some generalized coordinates. Each state of the system, in other words, its movement, corresponds to a certain trajectory of movement of the display point in the phase space. For ontology models with their poor mathematical structure (there is no topological or differentiable structure), the issues of roughness (structural stability) of systems are solved by creating discrete models. Therefore, in order to construct the ontology of the OPS, it is necessary to use data that relate to a certain period of time and a certain territory, obtained as a result of generalization over a set of observed parameters.
Various models of knowledge bases based on environmental and economic information and focused on the environmental assessment of the state of the environmental protection system are considered. Ontologies were developed using the methodology for constructing knowledge base in the "KARKAS" system.
An expert system (ES) is a computer system that allows, on the basis of a knowledge base compiled by experts from a specific subject area, to solve a problem with the help of a logical conclusion.
