  • Marine transportation system plays an important role in maintaining and promoting economic activities among countries. The accurate understanding of marine traffic flows are necessary for the further advancement of marine transportation system. While many existing researches on marine traffic have been conducted mainly on the basis of statistical analysis using traffic data, ship's traffic flow simulation model was developed in this study. A collision avoidance algorithm was conducted with categorizing of traffic factors such as ship's length and speed. The developed model was also verified by a simulation process.

  • This paper presents a method for designing layout on the yard and evaluating alternative designs of the layout by applying simulation. The design method is based on the concepts of the conventional port container terminal with yard layout, In general, yard design of the container terminal is consists of the two major parts. One is to divide yard area between the number of sections and the number of runs and the other is to decide the number of equipment that is the yard truck and yard crane. In the past days, this design was depended on the experience of the terminal operator and the reproduction of the conventional terminal layout because it is a very complex decision problem. In this paper, we suggest the method of yard design as a conceptual procedure and estimate the efficiency of the container crane and the optimal number of equipment using simulation. In the experiment results, the number of sections and runs on yard area, the number of yard truck per container crane and the number of yard crane per run are decided. In addition, the traffic flow among blocks on yard layout is estimated in terms of rate.

  • This paper proposes a method for designing layout on the yard and evaluating alternative designs of the layout by applying simulation The design method is based on the concepts of the conventional port container terminal with yard layout. In general, yard design of the container terminal consists of the two major parts. One is to divide yard area between the number of sections and runs and the other is to decide the number of equipment including yard truck and yard crane. In the past days, this design was depended on the experience of the terminal operator and the reproduction of the conventional terminal layout because it is a very complex problem to be considering facilities and equipments. In this paper, we suggest a design method as a conceptual procedure used simulation method The number of sections and runs on yard area, the number of yard truck per container crane, and the number of yard crane per run are decided using simulation In addition, the traffic flow among blocks on yard layout is estimated in terms of rate.
