An approach to modelling expertise in the environment pollution evaluation system

The article presents a summary of research activities performed in the field of knowledge representation of rapidly changing and complex environmental protection domain. The consideration is attached to the representation of expertise that could relate the use and analysis of information base and evaluation of circumstances of enterprise functioning that influence the environment pollution characteristics. The knowledge structures simultaneously express mutual object communication and decision-making processes in time. A unified framework is developed through the analysis of various types, aspects, and the role of knowledge relevant to the decision support system using Evaluation nets (the extension of Petri nets). The attention is paid to the representation of dynamic and static aspects of a target system and to the specification of decision-making processes describing general reasoning courses at different levels of detailing.
