In this study, we propose an RFID based container terminal operation process. Field tests are conducted for 900 MHz (truck identification) tag and 433 MHz RFID (container identification/e-seal) tag at an Incheon container terminal to verify possibility

  The powder blasting process has become an important machining technique for the cost effective fabrication of micro devices. This process is similar to sand blasting, and effectively removes hard and brittle materials. A large number of investigations o

  This paper addresses a the maintenance system based on the concept of RAMS (Reliability, Availability, Maintenance, Safety) for the effective maintenance of the urban transit. A systematic approach for developing a cost-effective maintenance strategy ba

  Presented in this paper was to evaluate and improve the usability of a web-based logistics information system. The system was developed for the domestic company to track and monitor its own transportation vehicles and for the customers to check the curr

This paper describes the NC simulator system for Wire-cut electrodischarge machining. Electrodischarge Wire-cut machining is applicable to all materials including metals, alloys, and most carbides. Although CAM system generate the NC code considering electrodischarge conditions, incorrect Wire-cut tool path bring about fatal results. The simplest way of simulating a EDM process is to display the trajectory of Wire-cutter location by line segments. With this kind of simulation, the programmer can get a general idea about whether the wire is moving as planned but cannot locate gouging or excess material because only the wire location will be seen, not the changes in the workpiece as it is machined. The ideal way of simulating the EDM process is to display the solid model of the workpiece as it is machined. Therefore we propose the ideal NC simulator system for Wire-cut EDM.

In this paper, we purpose the integrated TMS to solve the problem of current systems. The current system resulted in inconvenience because customers and users must contact to each system, when they want to know the information about orders. In this research, we develope a system with which customers and users can confirm all of order information from one system. To solve this problem, the information brought from two systems is integrated by constructing integrated database.

Globalization of Economic activities have increased Company's interests about International Logistics Management. Expansion of International trade depends on International Logistics which can overcome distance and time. In In-cheon, There are many small scale and minor Freight Forwarders take advantage of being linked with a port, an airport but their inefficient paper works cause raising of Logistics costs and losing of competitive power. In this study, we design a web based ocean forwarder information system for freight forwarder to solve these problems. So, this system will provide decreasing operation time, human resources, and accessing easily because of web based system, and finally decrease logistics cost and improve national competitive power.
