The optimal design of the complex technical objects using the ontological approach

The problems of automation of the complex technical object design, e.g. the aircraft, are studied. The main stages of the modern aircraft design using the computer information technology are considered. The optimal concept of aircraft design is presented by using the ontological approach and principles of analysis, decomposition and synthesis. In the article the data resulting from the design in CAD/CAM/CAE-systems at the stage of the objects allocation mock-up creation is used. Moreover, weight of the aircraft is taken into account according to the concept stage of the aircraft design and based on the data from previous stages. Ontological approach simplifies the process of optimal design, allows solving the basic problems of the modern design during the creation of the complex technical object, and helps coordinate simultaneous work of designers.
