Towards designing knowledge bases for aircraft malfunctions diagnostics based on model transformations

Abstract

The paper describes a method of forming prototypes of knowledge bases for the interactive electronic technical manual for RRJ-95 troubleshooting. The method includes three main stages: the formation of an ontology for diagnosing an aircraft malfunctions; the formation of event trees that describe the sequence of operations to eliminate specific malfunctions; the construction of knowledge bases that codify the basic concepts of the ontology and trees formed. At each stage, the following software are used: Protégé, Extended Event Tree Editor (EETE), and Personal Knowledge Base Designer (PKBD). Data-driven integration of software is implemented through model transformations. The description of the main stages of the method; the table of correspondences used in the implementation of model transformations, as well as an illustrative example are presented.
