System dynamics simulation modelling of a nautical and tourist port in relation to investments in sports objects will result in an increase of the quality of the total offer and an increase of competitive forces of the observed system. The system of nautical and tourist ports (LNT) has all the characteristics of a complex organization and business system, for which dynamic modelling efficient methods of simulation techniques have to be used. One of the relatively recent, and particularly exposed and practically proved scientific methods is system dynamics simulation modelling which was developed by the distinguished Professor Forrester in the famous world scientific center of the development of management science—The Sloan School of Management (MIT). In this paper, the business system of LNT will be determined through a global model of integral nautical and tourist service (from berthing service as a basic service to all other additional services). The subsystem of investments in new capacities, like sports and additional capacities will be determined by exogenous variable VINK—value of investments in new capacities.

System dynamic simulating modelling is one of the most appropriate and successful scientific dynamics modelling methods of the complex, non-linear, natural, technical and organizational systems. Investigation of behavior dynamics of the ship/s propulsion system as one of the complex, dynamic, non-linear technical systems requires application of the most efficient modelling methods. Marine Diesel engine start up system, which it is consisted of ship/s piston compressor and its driving electric motor, i.e. in this case asynchronous motor, shall be presented in the System Dynamics modelling approach in POWERSIM simulation symbolic and language. System dynamic models are essentially continuous models since the realities have been demonstrated by a set of non-linear differential equation, i.e. “equations of conditions”, however they are at the same time discrete ones because their principle time interval calculation i.e. (discretisation) sampling “DT” is determined in full compliance with (Sampling Theorem) by Shannon and Koteljnikov.

Simulation modelling, performed by System Dynamics Modelling Approach and intensive use of computers, 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. Gas turbine is a complex non-linear system, which needs to be systematically investigated as a unit consisting of a number of subsystems and elements, which are linked by cause-effect ( UPV ) feedback loops ( KPD ), both within the propulsion system and with the relevant surrounding. In this paper the authors will present an efficient application of scientific methods for the study of complex dynamic systems called qualitative and quantitative simulation System Dynamics Methodology. Gas turbine will be presented by a set of non-linear differential equations, after which mental-verbal structural models and flowcharts in System dynamics symbols will be produced, and the performance dynamics in load condition will be simulated in POWERSIM simulation language.

Internet traffic connection is nowadays not only desire, but also daily need on ocean going ships. Whether to download navigational charts or weather reports, upload vessel operational data, stream video conference with the shore office, or access centralized company databases, mariners need to be online in order to conduct business and stay in touch no matter where they may be located. On a personal level, the isolation of the seafaring life is also getting more difficult with shorter port calls and greater restriction on crew members going ashore due to national security concerns and great lack of free time to go ashore when onboard. Satellite technology is one of solution of the problem but it is and will be expensive due to costs that such equipment. Cost of link is large and data volume is small. Traffic routing and pondering data is technology that can significantly reduce costs, and better use of data volume provided by satellite technology. Example of real sailing plan of ocean going ship OOCL Netherlands on Atlantic express route ATX is shown. Example given demonstrates that time spent in port can be used to route link of onboard computers to terrestrial links such as WiFi or cellular data networks in order to cut the costs and increase volume of internet link for high volume and lower priority data.

The purpose of this paper is to present the efficiency of the application of the system dynamics simulation modelling in investigating the behaviour dynamics of the diesel engine complex system. The marine diesel engine is defined by a set of non-linear differential equations, i.e. by a continuous simulation model of a higher order and the so-called equations of state. At the same time, the simulation model is discrete as it strictly satisfies the chosen value of the fundamental integration time step DT. The paper presents a mathematical model of the system consisting of a marine diesel engine model, which forms the basis for designing a system dynamic qualitative model (mental-verbal, structural and schematic model) and a quantitative model (system dynamic mathematical and information simulation model). A scenario of mixed propulsion states has been presented. Parameters obtained with the aid of the hardware simulator Kongsberg ERS-L11 MAN B&W-5L90MC-VLCC Version MC90-IV have been used in conducting the simulation.

This paper discusses the traffic infrastructure development prospects of Bosnia and Herzegovina, as well as the expansion of the traffic to the port basin of Metkovic because of the overload of the port of Ploce which is the only and main port for transit traffic of Bosnia and Herzegovina. Bosnia and Herzegovina is a maritime-oriented country with exit to the sea in the small town of Neum. The tourist orientation of Neum has inhibited its development into an industrial port. Bosnia and Herzegovina has oriented itself to the port of Ploce as the exit to the sea. Besides, the advantages of these two ports are determined, brought by the construction of Corridor Vc, whose construction is planned by 2015. However, it will not be finished until then because the construction has not even started yet. It should be built as soon as possible because it will increase the transit traffic from Hungary through the port of Ploce.

Due to constant technological changes in the world of business, corporative training, which assumes permanent improvement and learning, is becoming one of the main prerequisites for job security and for obtaining qualifications for new employment. Many companies substitute the concept of permanent employment for investments in lifelong learning of their employees. Permanent knowledge and skill training are becoming the essence of employment. In the training system, the most important is education of top-employees, i.e. education of top-managers because of the level of their responsibility.

Intermodal transport is one of the most revolutionary and important phenomena in the 21st century regarding transport. This type of transport represents freight transport "from door to door" using at least two branches of transport without the change of freight unit. Recently in intermodal transport there is a greater use of radio-frequency identification RFID technology that enables electronic monitoring of intermodal freight during the entire transport time, loading trucks or wagons with freight, loading ships with the same freight to the port of unloading and transport continuation to the destination. The results of its use for private companies are reflected on monitoring the flow of freight and the higher market delivery speed, higher productivity and efficiency (which inevitably causes production process improvement), while for the countries it is important to improve national security, reduce traffic congestion etc. With regard to given facts, this paper shows the importance of RFID technology for the development of intermodal transport and it answers some of the crucial questions regarding its application.

This paper shows the possibility of system dynamics implementation when hiring shipping capacity in a shipping company. Three key variables will be put in relation to demonstrate how the system works: hiring shipping capacity directly through a shipping agent; shipping agent's offer closing delay because there is not enough shipping capacity, accepting the offer with the expansion of one 's own shipping capacity, hiring or buying other ships.Hiring exclusively through a shipping agent is in direct relation to the possibilities of the system expansion, which opens up the possibilities of market expansion, higher income and consequently higher net profit. Offer closing delay makes a significant link in the system because it raises the question of what is going to be gained, or lost, with the delay. The delay can mean that something is becoming incompetitive or unwanted on the market. Accepting the offer, with previous simulation of the employment optimization of the required shipping capacity, means company's business efficiency and represents it on the market as a reliable partner The possibility of expanding by renting the shipping capacity will depend upon freight or financial possibilities as well as decisions regarding the capital investment in new ships. The model was tested in real conditions through the example of the shipping company Atlantska plovidba Inc. The programme capacity DYNAMO from 2004 is used to show the simulation results.

In real management of shipping companies, the managers often use various models to select tracing control and methods for risk management which are inevitable in maritime activities. Research work on the risk problem area in shipping industry is a subject of interest for many scientists and experts. However, a single systematic approach to the problem is missing. Our economic organizations usually do not have the right methodology by which risk of running business is estimated, nor do they have manager approach to the problem of its management. Only banking, where management developed very good methods of risk measuring, and which manages risk very successfully, can be excluded from that assessment. However, shipping agencies have to broaden their understanding of the risk management, to understand that risk can also be a business initiator. The risk should not be afraid of because most of them can be managed. The project and its risks are directly connected with project aims: the more ready shipping company is to take over the risks in the project, the more business benefit will they have. On the other hand, a shipping company which plays safe will lower its possible benefits.

This paper deals with the application of System dynamics and Chaos theory in shipping using the example of freight rate forming. The development of new technologies, changes in structure and conditions, information accessibility, etc. are only some of the factors that intensify changes in freight rate forming in shipping. Therefore, shipping environment is becoming increasingly complex and dynamic. System dynamics seems to be a tool very suited for modelling of strategic and operational behaviour in shipping business. Due to the complex behaviour of these systems, chaos theory can also help in modelling of processes in shipping. The basic feature of chaotic systems is fine sensitivity in conditions at the beginning, when small change in input value may cause great changes in output values. By applying its concepts to the business process, as well as in freight rate forming in shipping, it prepares the business systems for quick response to the changes in the environment.

By the development of global communication network, technological assumptions of better distance learning have been realized. Distance learning is not a new model of education introduced by Internet, since this concept has already been brought into many correspondence schools, in educational radio and TV broadcasts, in educational CD-s, i.e. in all types of learning in which teacher and student are mutually distant from each other. In order to make this model of distance learning successful, communication must be achieved between a teacher and a student. Great support to distance learning communication is provided by various video conference systems. Such systems enable physical distance of the user and represent very useful appendix to other distance learning tools. The article deals with Distance Learning Model, in the context of which distance learning courses would be organized, firstly for the students of the Faculty of Maritime Studies and additionally for all other concerned attendants. Actually, there is a dilemma regarding distance education and schooling and also model of providing teaching courses. Many questions have arisen in terms if this distance learning model is appropriate and effective, and consequently we tried to offer some answers regarding efficiency of the distance learning model.
