History of Science and Engineering Annotation << Back Situational Modeling of Industrial-Natural Complexes Based on Conceptual Approach Zuenko А.А. Makedonov R.A. Fridman O.V. Fridman A.Ya. The article below exemplifies a situational approach to modeling of industrial-natural complexes based on an open conceptual model and software implementation of this approach with a model of a tailing pit of an apatite-nepheline ore-dressing plant. The model incorporates a geographical information system and an expert system. The paper describes some structural units of the software modeling system that provides forming of the model, manages simulation process and represents results of computing experiments. Keywords: situational modeling; industrial-natural complex; conceptual model; computing experiment. Contacts: E-mail: fridman@iimm.kolasc.net.ru Pp. 53-68.
