9.11 terrors which happen in 2001 in the U.S. recognize importance about national security and Department of Commerce, country safety department, Federal Communication Commission(FCC) etc. are establishing RFID sticking plan in harbor exit and entrance container for this, and it is real condition that is preparing preparation of law and system that establishes harbor peace law(Safe Port Act) on October, 2006 and acts on for U.S. about container load cargo Europe and Asia each countries. These law and system is logistics security that strengthen search for import and export freight and security to main contents. To meet in these circumstance subsequent, this paper is to examine the following three themes. First, examined necessity of logistics security and logistics security strengthening tendency, and second, examined in achievement of logistics business and RFID, and third, presented logistics security process that utilize change of realization about logistics security and RFID's role for logistics security. Through upper investigation, this paper suggested the realization about logistics security raising, logistics security connection system construction by export step, real-time freight chase that use RFID, construction necessity of executive system and development of logistics security equipment required.

The objective of this paper is to analyze the equipment combination of stevedoring system at port container terminal. In general, the productivity of container terminal is evaluated by productivity of container cranes at apron, but there are other equipment such as transport vehicles and yard cranes. Therefore, a method that can estimate the optimal equipment combination of stevedoring system in container terminal is required. We perform various simulation experiment and analyze equipment combination to improve the productivity. From the application of the case study, we demonstrated the savings effect using mean waiting time rates by the equipment combination.

Construction supply chain management (CSCM) has become one of the critical factors that determine the success of a construction project as it becomes increasingly complicated and mega-sized. Particularly for high-rise or mega-sized building construction, just-in-time supply chain management is required due to lack of storage space and effective logistics for construction components and materials at a construction site. Despite the fact that research and development of radio frequency identification (RFID) and wireless sensor network (WSN) technology have been performed, construction project managers still need to carry mobile devices and check material and component flow at each stage of the supply chain process. This research proposes that the equipment used in the construction supply chain process, such as movers, trailers, gates, and hoists, can become main actors in the supply chain process using RFID and WSN technologies. And the proposed equipment and process focused on a solution to the redundancy identification problem, which has been observed in operations that use RFID/WSN-based processes for construction logistics. This paper also presents issues identified through verification and validation of the research results and proposes further studies.

Large warehouses are building automation systems to increase efficiency. However, small warehouses, military bases, and local stores are unable to introduce automated logistics systems due to lack of space and budget, and are handling tasks manually, failing to improve efficiency. To solve this problem, this study designed small loading and unloading equipment that can be mounted on transportation vehicles. The equipment can be controlled remotely and is automatically controlled from the point where pallets loaded with cargo are visible using real-time video from an attached camera. Cargo recognition and control command generation for automatic control are achieved through a newly designed deep learning model. This model is designed to be optimized for loading and unloading equipment and mission environments based on the YOLOv3 structure. The trained model recognized 10 types of palettes with different shapes and colors with an average accuracy of 100% and estimated the state with an accuracy of 99.47%. In addition, control commands were created to insert forks into pallets without failure in 14 scenarios assuming actual loading and unloading situations.

To meet the soaring demand recently, South Korea big shipbuilders are examining two things. One is new investment in plant and equipment. The other is replacement of production resources. Considering plant & equipment investment and replacement of production resources, even if actual production ability would be enough, the real output could be affected by limitation of logistics with lack of analysis. As we set up big shipyard in virtual space, we could perform actual production by using confirm production plan in virtual space. We've analyzed the load of block stock, load of road and load of transporter for logistics effects are followed by production increase. This research is to determine the possible problems of those analyzed results and to present the resolution using the current layout. And then modified yard layout, we reanalyzed previous three logistics effects. This simulation model could help administrator to make rational decision for changing yard layout.

This study investigates cargo management issues in the shipbuilding and marine equipment industry. Problems are analyzed concerning the absence of information about exact cargo location and condition, damage, loss, replacement, and transportation delays during the import and export process. Then, improvements are proposed to solve these problems. To illustrate, real time information about the status and location of cargo should be communicated between import/export and logistics companies to facilitate material logistics for shipbuilding & marine equipment. In addition, a standard cargo classification and recognition system should be established to reduce delivery delays and mistakes, so then enhancing logistical efficiency. Moreover, it is also necessary to nurture professional shipbuilding & marine equipment forwarders to strengthen their expertise with professional education and training.

This study reconstructed the military logistics improvement project currently being implemented by ROK military as a defense logistics strategy. In addition the factors affecting the performance of the defense logistics strategy are analyzed using PLS. The significance of this study is as follows. First, the defense logistics improvement project was structured as a defense logistics strategy according to function. Second, PLS is used for performance factor analysis. Most of the existing defense researches utilized the ML structural equation. However, this study used the PLS structural equation in view of the fact that each detail project is the formation of defense logistics strategy. Third, we identified projects that have a substantial impact on defense logistics performance and those that do not. We found that inventory, process, and information strategy influenced logistics performance among defense logistics strategies. On the other hand, it was confirmed that the facility/equipment strategy had no significant effect on defense logistics performance.
