摘要

The System Dynamics Simulation Modelling and Optimisation Methodology is one of the most suitable and effective ways of dynamics modelling of complex non-linear, natural, technical and organisation systems. The System Dynamics Models are, in essence, continuous models because the realities are presented by the set of non-linear differential equations, i.e."equations of state". They are at the same time discrete models, because they used basic time step for counting i.e. discrete sampling DT, which value is determined in total accordance with "SAMPLING THEOREM" Shannon, Nyquista and Koteljnikov. With the choice of basic time step DT it is possible to do computer modelling of continuous simulation models on digital computer, which is very suitable for education of the marine students and engineers, because they can study complex dynamics behaviour of marine systems and process. Port is a place of interlace of different kinds of cargo, and it plays an important role in shipping process, connecting different types of traffic in one united system, and forms an interrupted traffic chain. The aim of this paper is: to show the efficiency of System Dynamics Simulation Modelling during the study of the dynamics behaviour of the port-transshipment system, and to find optimal solution for transshipment with regard to the type of the cargo and the size of the traffic of the cargo, direction and dynamics of arriving and shipping of the cargo.
