Simulation Model of Management of Shipping Company

摘要

Systematic dynamic simulation modelling is one of the most adequate and successful scientific ways of modelling dynamics of complex non-linear natural, technical and organizational systems. Systematic dynamic models are in fact continual models because the subject has been shown by a set of non-linear differential equations i.e. equations of state. However they are at the same time discrete because the basic time unit of calculation i.e. discretization DC has been determined completely in accordance with Sampling Theorem by Shannon, Nyquista and Koteljnikov. Such a selection of basic time unit (DC) enables a computer modelling of continual simulation models on digital computer which is very adequate for education of the students of marine studies, marine engineering and marine electrical engineering, as well as theoretic and practical training of marine engineers because it enables them, by the application of dynamic process, acquisition of new knowledge and skills about complex dynamics of the behaviour of marine systems and processes. Shipping company is a constitutional part of a dynamic model and its surrounding and it cannot be studied independently without interrelations. Shipping company according to this model has been divided into several separated units, Commercial Department, deposits on the account, shipping capacities, debts, demands, loans, goods for transportation. This paper has analysed system of dynamic model of subsystem of the money on the account, and subsystems of shipping capacity. The dynamics of the behaviour of all shipping company has been simulated.
