Abstract

Aircraft engines in the conditions when the idea of the current problematic situation are blurred, unclear and contradictory. Proposed a cognitive model allows for the structuring of the knowledge of experts, expressed as fuzzy categories, and develop on this basis, harmonization of the rules of the views of the expert group to prepare a wellfounded assessment of technical condition of the objects. The model is based on a collective causal cognitive map describing the influence, causality and system dynamics factors, symptoms and factors, the reasons for the study of the problem situation. A general scheme of evaluation of the technical condition of aircraft engines, in which implemented a set of interrelated processes of reception and information transformation that occur in the course of specially organized interaction of the object of research, software and hardware monitoring and diagnostics, as well as artificial intellectual environment, which allows to organize actions of experts aimed at an informed choice of appropriate version of the study.
