摘要：Simulation modelling, by means of System dynamics intensive use of modern digital computers, i.e. mass application of presently very cheap but very powerful PC's at the same time, is one of the most appropriate and succesful scientific research methods of the complex, non-linear, natural, technical and organizational systems. The methodology for system dynamics, i.e. relatively recent scientific branch, has shown its efficiency in practice as a very suitable means for scientific research which includes management problems, behaviour, sensibility flexibility and behaviour dynamics of many systems and proceses. System - dynamics computer simulation methodology, for dynamic modelling behaviour of many different non-linear ship electrical, thermodynamic, hydraulic, mechanic and pneumatic systems, was used by the students as studying materials for their graduation at Maritime faculty - Split in the period from 1991. to 2002. The aim of the paper is to demonstrate the efficiency of application of this method in investigation of behaviour dynamics which is one of complex marine systems and proceses, i.e. "gas -turbine generators". Twin shaft gas turbine and non-contact synchronous generator will be presented with mental -verbal, structural, mathematical computers models and a complex marine propulsion will be simulated.
