Description
Summary:Prognosis in landscape ecology is a task of dealing with a complicated natural system, ill or imprecisely defined, interactive, yet slow-response, permanently, mostly implicitly, changing in time. To cope with this problem, we decided to build an expert system (ES) equipped with: - the possibilities of using suitable exact models in precisely defined domains; - the facilities to delegate the solved problem when outside the possibilities of exact models to the heuristic production rule experience-based ES; - coping with uncertainty in its heuristic part: of a variable by its fuzzy definition and by weighting the variable; of a rule by weighting the rule; - the extensive use of accumulated experience, expressed linguistically; - the possibility of simulating response in slow-reacting systems.
