Описана формальная правдоподобная модель процесса разрушительного характера в геоэкотехносистемах, представляющих собой территориальные системы, дискретизированные посредством сетки из равновеликих ячеек. Предложенный формализм позволяет совмещать в рамках одной структуры различные оценки правдоподобия – нечеткие, вероятностные или приближенные.
Описано формальну правдоподібну модель процесу руйнівного характеру в геоекотехносистемах, що являють собою територіальні системи, дискретизовані сіткою з рівновеликих комірок. Запропонований формалізм дозволяє поєднувати в межах однієї структури різні оцінки правдоподібності – нечіткі, імовірнісні або наближені.
Purpose. The purpose of the work is the development of formal plausible model of destructive process propagation, suitable for the tasks solution of the natural emergency counteracting in the real time decision making systems. Method. The authors used the event-based approach for the developing the plausible model of the destructive process. The methods of fuzzy, probabilistic and rough sets were used to assess the likelihood of cell transitions between states. Results. The formal plausible model of the destructive process in geoecotechnosystems is described, having the form of territorial system, which is discretized using the grid of equal cells. The model of destructive process is represented as the formalism of plausible tree network of the events modeling the transitions of cells from one state to another and allowing to assess the likelihood of such transition and the time during which such transition is anticipated. The proposed formalism allows combining the different likelihood assessments, such as fuzzy, probabilistic and rough, in the frame of one structure. Conclusion. The proposed model can be used in decision support systems for the natural emergencies counteracting, which are based on geoinformation technologies. Using the proposed model allows increasing the efficiency of decision making in the natural emergency conditions by means of informational support.
