Logistic Support Analysis(LSA) and Logistic Supportability Review must be carried out as soon as possible in development stage in order to minimize operation/maintenance cost that head the list of weapon cost and improve logistic supportability of the weapon system. And the result must be used for hardware designs to set up to be able to input to the system design and logistic support elements. Therefore Logistic Support Elements must be planed/developed/supplied with the main combat system concurrently and performance and logistic supportability of the comabat system had better be improved mutually. This report describes maintenance concept changes of weapon systems, fault diagnosis function and test equipment state on the domestic MBT(main battle tank). And then it presents application and intensification of itself fault diagnosis system for a domestic future MBT considering connection with IETM(Interactive Electronic Technical Manual) and TE(Test Equipment).

Generally speaking, weapon system is defined as a combination of primary system and support system which are evaluated by capability and operational availability respectively. Recently comparison of total life cycle cost shows that logistic support system is proved to be more important than primary system. However, until now systematic approach to support system development has not been applied in the area of developing support system. We need to construct a universal metric for effectiveness of logistic support system and to cut out whatever activities or support elements which do not contribute to the metric. This paper describes a new approach based on system engineering approach to logistic support system and also classifies five factors of failure, stock-out frequency, administrative delay time, active repair time and logistic delay time that have influence on operational availability of logistic support system.

This paper is to establish rational logistic system practical study between korea and Japan. In this paper the five logistic function of korea business are classified and investigated and analyzed. And two, i.e., strategic and tactic, aspects of logistic system between two nations are compared with each other through practical study Finally this Paper Proposes a integrated logistic system exploiting the strength of both nations.

The development of information communication technology leads the growth of logistic industry including delivery service as well as electronic commerce. The researchers predict that it will be still improving for the next several years. The logistic information system of railroad courier has been growing for a long time with small-package delivery transportation which is similar to the land-road delivery system. Despite of the long-time growth, it is recently in pain of the great loss since the 1990's, due to the failure to satisfy the customer's need for door-to-door delivery service. But the logistic information system of railroad still has the great potential. There are so many benefits such as timeliness, Punctuality, speed, multi-node storage base, transportation efficiency, energy frugality, environmental sociability, and so on. If the railroad logistic system plays a role of a portion of the nation-wide logistic with other logistic system, the synergy through the balancing logistic will also get much of international competitive advantages. So the objective of this research is to design the model and prototype of the web-based logistic system from which railroad service provider(Korean National Railroad), delivery service providers, and the customers can share the best effective delivery information.

The purpose of this study is to examine the actual condition of environment conscious logistic system which is essential to make material recycling economic society. Environment conscious logistic management which meant simply recycle is tend to promote material reduction, reuse and recycling. We have made case studies about advanced environment friendly logistic system. To examine Korean companies' environment conscious logistic system, we made survey form which is consist of 82 questionnaires and 154 companies have participated for this. And we have analyzed the survey responses. As a result of this study, we propose the way of constructing environment conscious logistic system in Korea.

본 연구에서는 물류정보시스템을 도입활용하고 있는 무역업체들을 대상으로 내부업무효율성과 조직혁신정도를 조절변수로 하여, 내부업무효율성과 조직혁신정도가 높은 집단과 낮은 집단으로 구분하여, 이들 각 집단의 물류정보시스템 특성변수가 성과(이용자가치와 인식된 유용성)에 미치는 영향을 분석하였다. 연구결과, 구조화된 업무 환경에서 물류정보시스템을 통한 지속적인 업무수행과 더불어 조직혁신을 위한 기업차원에서의 노력이 병행되어야 하며, 물류정보시스템 도입 무역업체들은 정기적으로 기업의 업무활동전반에 대한 정확한 평가와, 전략수립을 통해 물류정보 시스템의 성과 제고를 위한 노력을 기울여야 할 것이며, 본 연구에서 나타난 바와 같이 물류정보시스템 도입 무역업체들의 낮은 조직혁신정도를 향상시킬 수 있는 조직자체의 각성과 노력이 뒤따라야 할 것이다.

In the paper We have analyzed the case study of the domestic and foreign railway logistic information systems based on the railway logistic to build the information architect basis system of real-time simultaneous. In case of domestic examples, We have analyzed the logistic information system used in Korea Railroad and the information systems of Kyungin ICD(Inland Container Depot) and Busanjin CY(Container Yard). In case of foreign example, we have analyzed the logistic information system of Japanese FRENS(Freight information network system) and the examples of freight tracking using RFID(Radio Frequency Identification). Through the above analysis, We have induced the main problems and improvement methods. We are able to build the railway-oriented information network system for the massive and efficient railway transportation.

The focus of this study is to represent a methodology of analysis for integrated logistic system by means of the Evolution Strategies and Data Envelopment Analysis(DEA). The integrated logistic system is composed of AS/RS (Automated Storages and Retrieval System), AGVs(Automated Guided Vehicle System) and Conveyor System. We design the simulation alternatives with choosing the qualitative critical factors for the each subsystem. Evolution Strategies is used to optimize the quantitative critical factors and responses of each alternative. DEA is applied to measure the efficiency of the alternatives in order to select the optimal operation efficiency scheme. The method of analysis which combines Evolution Strategies with DEA can be used to analyze the qualitative and quantitative critical factors in the integrated logistic systems.

Recently, RFID has emerged as the main technology in the logistic services. When the existing recognition technology based on bar codes brings about lots of problem due to its own limits. RFID becomes the center of attention to solve them. However, RFID is not without any obstacles: companies have their own operating systems, while RFID is developed regardless of each company's special features. RFID middleware system based on web service is expected to remove these obstacles. This paper shows how to operate the middleware based on web service and to lay in the DB the tag informations taken from reader system. Middle assures that companies adopting RFID system for their logistic service are given adaptability to any systems whatsoever, available by way of defining logistic information, tag information and reader information. For this purpose, we implement as the basic web service a middleware system that turns all data into XML(eXtensible Markup Language) of SOAP (Simple Object Access Protocol), the standard data.
