  • In order to streamline the procedure of data transmission in port and logistics industries, MOMAF introduced EDI systems as the method of data transmission of 19 documents 5 years ago. While operating EDI system, MOMAF has found the inconvenience and the inefficiency of using EDI systems in the field of requesting fast response. This thesis focuses on finding the possible fields of on-line processing system instead of EDI system and suggests the economic effects occurred by the on-line processing system. The result of the paper presents that if data transmission area such as 'ocean vessel entrance report', 'application for using tug boat'and 'application for pilot'is changed to on-line processing method, the processing cost and time will be reduced compared with EDI processing method.

  • In this paper, modified two-port time-domain passivity approach is proposed for stable bilateral control of teleoperators under time-varying communication delay. We separate input and output energy at each port of a bilateral controller, and propose a sufficient condition for satisfying the passivity of the bilateral controller including time-delay. Output energy at the master port should be less than the transmitted input energy from the slave port with time-delay, and output energy at the slave port should be less than the transmitted input energy from the master port with time-delay. For satisfying above two conditions, two passivity controllers are attached at each port of the bilateral controller. A packet reflector with wireless internet connection is used to introduce serious time-varying communication delay of teleoperators. Average amount of time-delay was about 190(msec) for round trip, and varying between 175(msec) and 275(msec). Moreover some data packet was lost during the communication due to UDP data communication. Even under the serious time-varying delay and packet loss communication condition, the proposed approach can achieve stable teleoperation in free motion and hard contact as well.

  • As the containership has been large-sized, it is important to analyze the social feasibility for the dredging the water-depth of Busan port. We tries to do an exploratory study to analyze the needs of the core port user group by using the survey methodology. We did the survey for the ocean carriers, terminal operating companies, ship pilots respectively. Collected data was analyzed by frequency and cross tabulation method. Result suggests that the Busan North Port should be dredged to the 16 meter depth and Busan New Port should be dredged to the 17 meter depth. And the priority of the depth dredging is ranked as Gamman pier, Sinsundae pier, New Port and Jasungdae pier.

  • From the viewpoint of physical distribution, the port transport process can be regarded as a system which consists of various subsystems such as navigational aids, quay handling, transfer, storage, information If management, and co-ordination with inland transport. The handling productivity of this system is determined by the production level of the least productive subsystem. So, a productivity analysis on the flow of cargoes through each subsystem should be made in order to achieve efficient port operation. The purpose of this paper is to analyze the productivity of each subsystem in Pusan port, and to bring forward problems and finally to draw up plans for their betterment. Analyzed results on the productivity of each subsystem are as follows, i) It is known that the number of tugs with low HP should be increased by a few, the number of tugs with medium HP is appropriate, and the number of tugs with high HP is in excess of that necessary. ii ) In the case of container cargoes, it is found that the transfer and storage systems in BCTOC have the lowest handling capability, with a rate of $115\%$, leading to bottle-necks in the port transport system, while the handling rate of the storage and quay handling systems in general piers is in excess of the inherent capability. iii) In the case of the principal seaborne cargoes passing through general piers, there is found to be a remarkable bottle-neck in the storage system. In the light of these findings, both the extension of storage capability and the extension of handling productivity are urgently required to meet the needs of port users. Therefore, iv) As a short-term plan, it is proposed that many measures such as the reduction of free time, the efficient application of ODCY, etc must be brought in and v) In the long-trun, even though the handling capability will accommodate an additional 960,000 TEU in 1991, the scheduled completion date of the third development plan of Pusan port, insufficiency of handling facilities in the container terminal is still expected and concrete countermeasures will ultimately have to be taken for the port's harmonious operation. In particular, the problem of co-ordination with inland transport and urban traffic should be seriously examined together in the establishment of the Pusan port development. As a method of solving this, vi) It is suggested that Pusan port (North port) should be converted into an exclusive container ternimal and overall distribution systems to the other ports for treating general cargoes must be established. vii) And finally, it is also proposed that the arrival time (cut-off time) of influx cargoes for exports such as general merchandise and steel product should be limited, with a view to securing cargoes suitable for the operational capability of BCTOC.

  • Linear motor (LM) based shuttle cars will play an important role in the future transportation systems of marine terminals to cope with increasing container flows. These systems are known as agile port terminals because of their significant advantages. However, routing for multiple shuttle cars is still an open issue. We present a network model of a container yard and propose constrained dynamic programming (DP) for its routing strategy with collision avoidance. The algorithm is a modified version of typical DP which is used to find an optimal path for a single traveler. We evaluate the new algorithm through simulation results for three shuttle cars in a mesh-type container yard.
