The purpose of this study is to let the entire logistics system be managed in cyberspace by effectively sharing the logistics information between companies involved in the process, changing conventional commerce to electronic commerce. Most of the goods traded through electronic commerce are small goods involving small business transactions. This produces many problems in shipping and delivery and the leads an inefficient logistics system. Another problems is that there is no sharing of information that process the logistics flow and no systematic management of pick-up and delivery information. As a result, rise in logistics cost, longer delivery period and poor service quality are inevitable and these results are becoming an obstacle in the widespread usage of the electronic commerce. Companies that are part of logistics center can cooperate logistics business in Cyber space and share the entire logistics information through the cyber logistics center. This turns out in effective sharing of logistics information, and thus, allows efficient management of logistics, improves logistics service, and reduces logistics cost.

최근 물류를 가장 효과적으로 수행할 수 있는 물류관리의 한 형태로 제3자 물류가 가장 유용한 수단으로 관심을 받고 있다. 그러나 물류의 이러한 추세 속에서도 물류를 아웃소싱하지 않고 자사가 직접 물류활동을 수행하면서, 그에 못지않게 경쟁력을 확보하면서 물류를 수행하는 기업도 적지 않다. 이를 상황적합이론 관점에서 보면, 기업이 처한 물류 환경 및 특성에 따라 적합한 물류관리 유형은 달라지게 되며, 이러한 적합관계에 따라 물류성과도 달라지게 된다. 본 연구는 이러한 맥락에서 기업의 물류특성과 물류관리유형 간의 적합관계와 이들의 적합관계에 따른 물류성과의 차이를 실증적으로 분석하였다. 실증분석 결과 물류업무의 중요성과 물류업무 비중 및 수출비중이 높을수록 제3자 물류가 적합관계를 이루며, 물류비 비중이 높을수록 자사물류가 적합관계를 이루는 것으로 나타났다. 그리고 기업의 물류특성과 물류관리 유형간의 적합관계를 이루는 기업이 그렇지 않은 기업보다 물류비용 절감효과와 물류운영 효율성이 높은 것으로 나타났다.

Generally the life-cycle cost of complex systems composed of several sub systems or equipments such as train, aircraft weapon systems is spent much more during operation and maintenance phase than development phase. The maintenance cost for maintaining the availability and extending the life span of systems comprise a large proportion of systems operation cost. The cycle of preventive maintenance affects operation and maintenance cost a lot. In this study we introduce a way minimizing life-cycle cost of systems by calculating more reliable preventive maintenance period than the results of previous study using systems reliability data considered the reliability and failure effect ratio of sub-systems or components. We can solve the preventive maintenance period problem known as NP-Hard as quick as possible by using modified genetic algorithm than using other models introduced in previous study.

At the present, e-commerce takes the place of existing transaction form in structure in the world trade by advancement of Information Technology and diffusion of Internet. There is no exceptions of this tendency even in industry of maritime and logistics. So, global shipping lines and logistics companies try to construct the e-Business network system for increasing their competitiveness in an are of cyber. However, in Korea, most of companies prefer "final handshake" as the traditional way of transaction to "e-commerce", because they bear a distrust in mind about the outflow of transaction information and security of settlement. So, number of companies using e-commerce is very small, and this situation causes the limited factor for activating the transaction structure of it. The rate of using e-commerce in logistics industry is lower than other industries, even more higher effectiveness is expected when they use it. Especially, it is very necessary not only e-commerce but also e-Logistics which can serve information of freight cost on cargo flow, operation cost and schedule, and tracing information of cargo. Increasing the necessity of e-Logistics, this study research the rate rf using e-Logistics focused on maritime and logistics companies, and analyze the transaction form among members of these industries for improving them. In detail, this paper examine the drivers for activating e-Logistics, and present the effective factors for a successful development of these industries.

All over the value chain, a logistics information system must satisfy several requirements about gathering and sharing related information. For example, distributors or forwarders need up-to-date information for scheduling and managing their logistics resources. Meanwhile, consignors or consignees want to know the dynamic information about current states or location of their goods. Such information is dependent upon the quality of data sets collected throughout the logistics processes. Thus, gathering accurate data promptly is the essential factor for the success of a logistics information system. However, there are limits in reducing both time-gap and man-power for datn sourcing, since this process is done manually or by using bar codes and scanning devices. Smart-tag can be the alternative to such n time-consuming and inefficient operation, especially for handling piles of goods. The tag includes a micro-chip containing data which is remotely readable by readers with antenna. Logistics system with Smart tag can provide all the information anywhere and anytime, and it will increase the efficiency of logistics and satisfaction of users. In this paper, we propose a conceptual architecture for smart-tag based logistics system and describe its functions.
