Evaluating an operation principle practicability of new technical system

This study presents an approaches for evaluation of synthesized structures of the physical operation principle of designing technical systems on the basis of Graph theory and the mathematical tools of Petri nets and Bayesian networks. The developed synthesis methods show an increase of the performance and quality of computer-aided design of technical system as compared with the existing software systems of the physical operation principle synthesis as a result of ignoring the unrealizable structures.
