Simulation modelling, performed by System Dynamics Modelling Approach-MIT and intensive use of digital computers, which implies the extensive use of, nowadays inexpensive and powerful personal computers (PCs), is one of the most convenient and most successful scientific methods of analysis of performance dynamics of nonlinear and very complex natural technical and organizational systems [1]. The purpose of this work is to demonstrate the successful application of system dynamics simulation modelling at analyzing performance dynamics of a complex system of ship’ s propulsion system. Ship turbine generator is a complex nonlinear system which needs to be analysed systematically, i.e. as an entirety composed of a number of sub-systems and elements which are through cause-consequence links (UVP) connected by retroactive circles (KPD), both within the propulsion system and with the corresponding environment. Indirect rocedures of analysis of performance dynamics of turbine generator systems used so far, which procedures are based on the use of standard, usually linear methods, as Laplace’ s transformation, transfer functions and stability criteria, do not meet the current needs for information about performance dynamics of nonlinear turbine generator systems. Since the ship turbine generator systems are complex and the efficient application of scientific investigation methods called qualitative and quantitative simulation methodology of System dynamics will be presented in this work. It will enable the production and application of more and varied kinds of simulation models of the observed situations, and enable the continuous computer simulation using high speed and precise digital computers, which will significantly contribute to the acquisition of new information about nonlinear characteristic of performance dynamics of turbine generator systems in the process of designing and education. Successful realization of this work, or qualitative and quantitative scientific determination of a complex phenomenon of performance dynamics of load of the ship electric network, or ship turbine generator system, will give a significant scientific contribution to the fundamental and applied technical scientific fields, and to interdisciplinary sub-directions of maritime transport, exploitation of ship drive systems, mariners education, automatics, theory of management and regulation, expert systems, intelligent systems, computerization and information systems. The contribution may also be significant in the process of education of the present and future university mechanic and electric engineers in the field of simulation modelling of complex organisational, natural and technical systems.
