The port throughput situation has changed since the 2008 financial crisis in the US. Therefore, we studied the situation, accurately estimating port traffic of Korean port after the 2008 financial crisis. We ensured the proper port facilities in response to changes in port traffic. In the results of regression analysis, Korean GDP and the real effective exchange rate of Korean Won were found to increase the container throughput in Korean and Busan port, as well as trade volume with China. Also, the real effective exchange rate of Korean Won was found to increase the port transshipment cargo volume. Based on the ARIMA models, we forecasted port throughput and port transshipment cargo volume for the next six years (72 months), from 2015 to 2020. As a result, port throughput of Korean and Busan ports was forecasted by increasing annual the average from about 3.5% to 3.9%, and transshipment cargo volume was forecasted by increasing the annual average about 4.5%.

H maritime company in Korea had a long history of difficulty in obtaining enough empty containers to transport its commodities. Despite efforts to resolve the problem, the repositioning of empty containers between depots was still planned manually, which consumed much worker time. To automate the generation of reposition plans, we developed a planning system to optimize the company's reposition of empty containers between global depots with a linear programming model functioning as a key decision engine in the system. The model determines the route, volume and mode of transportation for repositioning empty containers from depots with surplus containers to those requiring containers, as well as the empty space of ships generated from the unloading or loading of full and empty containers. The system has been in operation in the company's global network since March 2008.

Used motor oil contains pollutants, including organic chemicals and meta]s. When disposed of improperly - in the trash, on the ground or in a sewer system - the pollutants may reach rivers, lakes or the ground water. Thus, all the waste oil products such as waste motor oil, waste oil container, and waste oil filter should be collected and transported for recycling or disposal by waste oil regulations. Because waste oil container is a valuable resource, waste oil containers can be reused, cleaned, buried, and burned for recycling processes. This paper presents the integrated management system that may increase the efficiency and productivity for collecting and reprocessing waste oil containers such as steel can and plastic container. The integrated management system consists of collection and transportation process management system and confirmation and certification process management system for waste oil containers.

In this paper, we explore a novel transportation container in the marine terminals. The container includes Smart Tag embedded with radio frequency(RF) chips, which is used to access information about productions and possibly incorporated with GPS systems for integrated managements of them. The proposed mechanism is valuable for decreasing cost, increasing satisfaction of customers, and preventing economic loss due to production missing, thus increase of economic efficiency is highly anticipated. Consequently, accurate and proficient management is considerably accomplished in overall procedures of inventory and currency by means of the proposed systems.

컨테이너 터미널은 게이트 시스템, 장치시스템, 이송시스템, 적양하시스템 등의 하부시스템으로 구성되어 있어서 시스템의 최적화가 요구되며, 운영에 있어서도 장비, 인력, 장치장 등 제한된 자원을 효율적으로 사용하는 것이 터미널 경쟁력 강화 측면에서 중요하다. 본 연구는 신항만 개발시 터미널 설계에 사용될 수 있는 시뮬레이션 모형을 제안하는 것이 목적이다. 문헌 조사를 통하여 기존 연구의 한계점을 도출하고 이를 보완하는 시뮬레이션 모형을 설계하고 모형을 개발하였다. 또한 가상의 터미널 개발을 가정하고 일부 모듈을 적용하여 신항만 개발시 요구되는 안벽길이, 안벽 크레인 수, 장치장 규모 등을 도출함으로써 제안된 시뮬레이션 모형의 활용 방안을 소개하였다.

Logistics security has been enhanced to control cargo containers effectively and safely in global logistics. In response to the change, This study describes the system now being developed that tracks container position, watches cargo security status and gets informations of surrounding until the cargos arrived at its destination. We examine completion and satisfaction of the product for prospective users. For this, considering earlier studies about customer trust, satisfaction, service quality and purchase decision, we analyse an effect among the variables empirically. As a result, when the program is released, we examine customers' satisfaction and purchase decision for the informations to be offered from the program.

Although companies have to concentrate on effort to save cost to survive competition, transportation costs are taking more portions in total sales costs due to globalization in the modern times. It is the reason why Transportation Management System TMS is getting more important. However, it is practically difficult for the system to fit to all of transportation environments and actually many problems are taking place with the system. Therefore, a new idea is necessary to solve such problems fundamentally rather than temporarily or superficially. To do so, if TRIZ, which is a theory that systematically establishes creative ideas on the basis of patent analysis, is employed, it can bring forth a guideline with some creative principles that can be applicable in drawing out innovative ideas based on conceptual shift. The present study aims to propose a methodology of how TRIZ should be applied to solve the problems that happen in TMS as a whole. Particularly, the study focuses on how to design customized TMS system that can be employed for each of different situations in a creative way.

Purpose : The purpose of this study is to find that Factors in the practical application of LISMB(Logistics Information System Practice Based) on S.P(Smartphone)' Characters. and take in the whole situation of LISMB on S.P' Characters by this research and it is clear from the findings that LISMB on S.P' Characters situations and distinctiveness. Research design, data, methodology : Research model and hypotheses have been developed based on literature review and working-level interview The collected data were analysed with structural equation modeling, examining the hypothesized relationships and mediating effect. Result : The results of research are as follows, First, LISMB on S.P' Characters has a positive effect on a precariousness of operation management. but That has no effect on a precariousness of general management. Second, Consign management and User non-cooperation has a mediating effect on relationships between LISMB on S.P' Characters and general management. Third, Old version system, User non-cooperation and Unskilled in equipment new system has a partly mediating effect on relationships between LISMB on S.P' Characters and operation management. Conclusion : Smart-phon Prevalence rates keeps increasing. Nevertheless, LISMB on S.P' Characters may no be used in Container transportation market. This problem are being blamed for hampering corporate activities and harbor logistics industry development. so we need new way to solve that problem.

철도-공로 복합화물운송은 최초출발지에서 최종목적지까지 화물을 수송함에 있어 철도와 화물자동차를 연계하는 운송시스템이다. 철도-공로 복합화물운송에서 공로(화물자동차)의 역할은 집배송 기능으로 전체 운송과정의 경쟁력에 중요한 영향을 미친다. 본 연구는 철도-공로 복합화물운송의 대표적 화물인 컨테이너를 대상으로 집배송 부분의 효율성을 제고시키기 위한 운송전략을 개발하고 평가하는 데 목적이 있다. 이를 위해 컨테이너트럭의 운송거리 최소화를 지향하는 전략과 고객에서의 대기시간 최소화를 주목적으로 하는 전략 등 2개의 집배송 개선전략이 개발되었다. 개발된 전략들은 파리수도권의 실제 집배송망에 적용되어 그 효율성이 비교, 평가되었다. 기존 집배송방식과의 시뮬레이션 비교결과 제안된 전략들이 다양한 성과지표에서 상당히 효율적임이 입증되었다.

본 논문에서는 컨테이너화물 안전수송에 사용되는 ConTracer에 활용할 2.45GHz 및 GPS 통합 안테나 보드를 설계하고자 한다. 설계된 통합 안테나 보드는 컨테이너 도어에 적용하고자 컨테이너 도어에 해당되는 모형 모델링하여 철재물에 대한 RF 영향에 대해 시뮬레이션하여 그 결과를 반영하여 2.45GHz 안테나 보드를 설계하였으며 GPS 안테나는 세라믹 재질로 제작하였다. 적용하는 ConTracer라는 것은 각 컨테이너화물의 정보를 거점별 리더기로 서버측에 전송하는 장비로서, 항만 물류산업에 크게 활용되는 장치이다. 이 ConTracer 장비에 사용되는 2.45GHz 및 GPS 안테나 보드는 컨테이너 환경에 초점을 맞춰 설계할 필요가 있으며 컨테이너 재질(전부금속), 컨테이너에 실장되는 RF 모듈단의 크기와 접지를 모두 고려한 통합 안테나 보드 설계가 필요하다. 따라서 본 논문은 컨테이너 도어 부분만 모델링하여 최적의 안테나 파라미터들의 성능이 구현될 수 있도록 2.45GHz 안테나 보드를 제작하고 세라믹 재질로 GPS 안테나를 제작하여 그 특성을 측정하였다.
