Sheketa V. Information system for forecasting of oil and gas deposit

Plant of a research: the tasks of development and introduction of information systems based on knowledge bases for oil and gas application the domain. The purpose of a research: the analysis of information activity of the expert - geologist for development and realization of new methods of work with the expert and handling of the acquired knowledges, problem solving of acquisition both representation of knowledges and inference in conditions of an incomplete and inexact information oil and gas application domain. The strategy of phased formalization of knowledges of expert-geologist with using the values of type "is unknown" is suggested. The formal-logical apparatus for the presentation and use the knowledges an oil and gas application domain on the base of fuzzy sets theory is developed and the mechanism of inference for the information system is designed. The complex strategy of acquisition and processing the knowledges during the interactive dialogue "expert -engineer on knowledges- information sy stem " is developed.
