Suprunenko O. Functional and simulation modelling of technical system with the help of modified Petri networks

Dissertation work is dedicated to improvement and development of the new methods modeling technical systems with multiversion complex structure and parallel processes. The new modification of the Petri networks was designed. The combined method of modeling joining the functional modeling with modified Petri networks and simulation methods was created. "Mirror" correction computing model of elements raising its adequacy degree was offered. The modeling environment for investigating the technical systems with multiversion complex structure and parallel processes was created on base of the multifunction is designed. The building rules and investigation of the model functioning in the environment was designed on base of the modified networks Petri. The environment has a subsystem of input data optimization and "mirror" correction of the models, the work of which is based on the expert data. These subsystems allow researching the built models in the automated mode, to raise the quality of taking the technical decisions. The application of the combined method of modeling was illustrated on the example of the traveling salesman's problems, stochastic network planning and while creating and investigating the models of cinematic system accuracy.
