International Civil Aviation Organization adopted the program to improve performance of aviation-related data systems through the ASBU for 20 years from 2013. Research and development for integrated management network of aeronautical telecommunication data through SWIM(System Wide Information Management) technology which is part of program, are being progressed in the United States and European countries. Therefore, in this paper, we suggest a method of testbed implementation based on technology of aeronautical data services architecture applied the concept of SOA(Service Oriented Architecture), development of future data management model for integrated management of aeronautical data, and development of user-centric integrated aeronautical data management network through adapter technology for interoperating legacy aeronautical data system to develop even technology with development trends of advanced countries.

최근 인터넷이 대중화되면서 웹을 통한 전자상거래가 점차 늘고 있다. 이에 따라 웹 기반전자상거래를 위한 문서교환의 표준화 연구는 여러 기업의 참여 하에 활발히 진행 중에 있으나 아직까지 전자상거래의 일부 절차는 체계화되어 있지 않다. 가장 활발한 전자상거래형태인 오픈마켓을 통한 중계판매에서 상품제조업체, 판매업체, 오픈마켓(중계판매업체) 간의 전자적 상품정보(e-Catalogue)교환은 거의 이루어지지 않고 있다. 이런 이유로 오픈마켓을 통한 전자상거래에서 상품을 판매하는 판매업체는 상품정보를 직접 수집하거나 가공하여 이를 오픈마켓에 등록한다. 실제로 이러한 상품정보 교환 과정에서 많은 인력과 시간이 소비된다. 본 논문은 이러한 문제점을 해결하기 위해 RFID ODS 기술과 ebXML 기술을 활용하여 상품제조업체와 판매업체, 판매업체와 오픈마켓 간의 상품정보를 공유할 수 있도록 하는 새로운 모델을 제안한다.

본 연구에서는 AFTM이 필요한 이유를 항공기의 불확실성을 들어서 설명 하였다. 불확실성의 원인으로 수요, 수용량의 불확실성과 ATFM의 조정행동과 타이밍조정을 위한 불확실성에 근거하여 알아보았다. 이와 같은 불확실성을 줄이기 위한 방법으로는 정보 질의 향상과 다양한 가능성에 대한 문제를 예측하여 최적화하는 방법으로 해결할 수 있다. 슬롯교환메커니즘에서 가장 기본적인 알고리즘으로는 압축방법에 대하여 살펴보았고 항공사내에서 처리할 수 있는 항공사 슬룻 대체알고리즘을 설명하였다. 그러나 한 항공사에서 대체할 수 없는 경우에는 다른 항공사에서 대체 항공편을 제공하는 메커니즘에 대하여 알아보았다. 이어서 압축방법의 기본이론인 일괄처리방법과 SCS 의 신속대응메커니즘의 차이점과 장단점을 살펴보았다. 이어진 연구과제로 두 모델의 수학적 모델을 연구하여 그 특성을 파악하여 모델을 개발하여 시뮬레이션 하는 것이다. 더 나아가서는 메커니즘의 모범 예제라 할 수 있는 SCS 에서 실제적으로 어떻게 적용되고 있는지 사례에 대하여 연구하려 한다.

The national boundary's meanings turn to weak according to advent of Global enterprises. The place for design a product and marketing are separated to actual market. R&D is to the area where the knowledge activity is well, and low skilful product assembling is to the place the low wage is acceptable. It shows that the importance of net work structure. From early 90's, production system is diversified to markets where with the consumer as the central as multifarious items and creation new demands through consumer's participation into manufacturing process. This phenomenon show that logistics structures adapt to demand of technical variation, and the development of e-business with VAN(:value added network) and EDI(:Electronic data interchange) prove it. This study tried to analyze utilitarian assay about systems those land, sea, air logistics through documents research, and this study also present the direction of logistics system of airline company and goal of development on the based to the model of domestic airline company accordingly.

It is well known that any maintenance works for aircrafts must be carried out strictly in accordance with the specified maintenance manuals, especially for military airplanes. According to our previous studies, the largest portion of the maintenance jobs for military aircrafts is found to be related to the assembly/disassembly of various parts, which requires precise understanding of the work procedures as well as correlation between interconnected parts let alone grasping of the exact shapes of parts involved. However, the conventional manuals for aircraft maintenance have failed to provide enough information required for the efficient maintenance except for simple texts and vague pictures, which are far from being sufficient sets of information. On the contrary, unlike incomplete conventional manuals with poor contents, 3D modeling SW could provide us with not only powerful visualization tool even to see through inside any assembly but also freedom to watch parts under test from any angle we want. In addition, the maintenance personnels could learn the precise maintenance procedures through repeatedly watching 3D animated version of the maintenance work as if they were on the field. In this study, we have suggested the efficient procedures to develop 3D manual for aircraft maintenance using 3D modeling SW, Solidworks and implemented a 3D maintenance manual for Integrated Drive Generator(IDG) in Boeing 747. Characteristics of the developed 3D manual has been analyzed in comparison with the conventional ones as well. It is shown that the suggested method could be easily applied to develop a 3D maintenance manual for commercial airplanes since the maintenance works involving assembly/disassembly of major parts are very similar regardless of aircraft types.
