Many of logistics-related research in automobile industry has focused on inbound logistics and procurement. Research into outbound logistics is relatively few. As a starting research into outbound logistics in automobile industry, this paper examined its logistics network problems with three aspects - location strategy, inventory strategy and transportation strategy. We proposed alternatives of logistics network design resolution, and presented three practical scenarios based on those alternatives. Based on interview, on-site visit and internal data collection processes, we identified major domestic outbound logistics problems such as redundant logistics bases, inefficient delivery policy, insufficient inventory capacity, inventory stock quality deterioration, inefficient transportation system, and etc. In order to cope with those problems, we proposed such strategic alternatives as introduction of hub-and-spoke system, integration of logistics bases, introduction of (automatic) parking building, diversification of transportation mode, and etc. At the same time, we constructed three practically executable scenarios based on those ideas. The first is "Center Hub" scenario, the second is "Metropolitan Hub" scenario. The third and last scenario is "Regional Consolidation of Warehouses (distribution centers)".

산업 현장의 기계 시설물 고장 문제는 큰 인명피해와 경제적 손실을 초래할 수 있기 때문에, 기계 시설물의 상태를 기반하여 고장을 진단하는 것은 대단히 중요하다. 따라서, 본 연구에서는 전류 센서 데이터를 활용하여, 시설물의 고장 여부를 진단할 수 있는 알고리즘을 제안한다. 본 연구에 활용된 전류 센서 데이터는 x, y, z축을 가진 3상 전류 데이터로 구성되어 있으며, 2kHz로 1초간 샘플링 되어 있다. 본 연구에서는 2차원적 특성을 가지는 전류 센서 데이터를 분석하기 위해 CNN(Convolution Neural Network)을 활용한다. 시설물의 고장진단에 가장 적합한 모델을 선정하기 위해 CNN의 대표적인 백본 네트워크를 활용하여, 결과를 비교하였다. 실험 결과, 본 연구에서 구성한 후보 백본 네트워크 중 ResNet의 분류 정확도가 98.5%로 가장 높게 나타났다.

This study set out to develop a logistics rationalization model to reduce logistics costs including return route costs by using open information systems that overcame the limitations of the old closed logistics systems by the corporations and applying the principle of freight car sharing among them. In recent years, information infrastructure that can be easily shared by many such as information networks, however, One of the causes of rising logistics costs is high empty transfer rates on return routes after goods are transported from the distribution center of each company to consumption sites, It is propose to promote logistic efficiency and innovation. The study especially identified a logistics rationalization plan by examining and analyzing the stages of transportation on the circulation route of a distribution system from the distribution center of a corporation to consumption sites and the empty transfer rates and their current state.

Currently, despite having active movements related to port logistics security, there is lack of awareness, education, and security systems related to port technology. Before implementing port logistics security, a mutual authentication agreement should be reached through the establishment of an integrated network that can share port logistics security information in real time. In order to achieve port competitiveness and strengthen logistics service, establishment of national strategy for logistics security is necessary. However, there is an urgent need to raise the security consciousness among the port logistics organization members and enhance the information security ability which is a crucial feature of the port logistics organization. Therefore, the objective of this study is to analyze the factors affecting the information security capacity of port logistics organization members. Even though the analysis rejected the hypothesis that security regulations affect security awareness, the security activities and security awareness were significantly correlated. It also has a positive impact on the relationship between security norms and security abilities, and security awareness and security abilities.

최근 유비쿼터스 환경을 실현하기 위한 노력이 활발히 진행되고 있다. 대표적으로 센서 네트워크를 예로 들 수 있는데, 센서 네트워크란 다양한 위치에 선치된 태그와 센서노드를 통해 사람과 사물, 환경정보를 인식하고 그 정보를 무선으로 수집해 언제 어디서나 자유롭게 이용할 수 있도록 구성된 네트워크를 의미한다. 이를 실현하기 위해 센서 네트워크를 적용한 물류, 환경제어, 홈 네트워크, 헬스케어, 교통 등 다양한 응용분야가 적용되고 있는 가운데, 센서 네트워크 분야는 거대해지고 응용분야가 확장될 것으로 예상된다.

Today as the scale of e-commerce constantly expands, the number and the amount of the consumer frauds are also increasing very rapidly, without sufficient levels of systematic support to prevent them. Internet Escrow service is one of the promising payment mechanisms, which guarantees secure electronic trades and payments. Especially, if the real-time product delivery information is available via RFID-based track-and-trace environment, the security and efficiency of the Internet Escrow services would be improved a lot. In this research, proposed a novel approach to integrate EPCglobal Network, which is a de-facto standard for RFID-based information network model, with Internet Escrow services. The proposed service model was implemented in the form of "Integrated Financial Platform", which supports the contracts among trading partners and the payment via Escrow services by being fully integrated with bank systems. Using the implemented EPCglobal Network-based Escrow service system, we would be able not only to shorten the money-flow cycle and to develop new kinds of loan services, but also to overcome the problems of existing Escrow services including the lack of product-related information and the delay of purchasing decisions.

In this paper, we have developed RFID systems with integrated tag location data for efficient logistics information systems. These are consist of RFID readers with GPS module and RFID networks to service tag location data. The developed RFID readers can get location informations Of the tags, transfer them high speed by TCP/IP protocols, and operate as web servers. And we presented a simple service network system based on EPC network to service both location and tag data. The proposed system can be applicable to tracebility or finding locations of the products.
