Most recently, offshore Engineering & Construction field is concerned about integration management technology such as CIM(Computer Integrated Manufacturing), PDM(Product Data Management) and Enterprise Information Engineering in order to cope with the rapid change of engineering and manufacturer specification as per owner's requirement during construction stage of the project. System integration and integrated data modeling with relational database in integration management technology improve the quality of product and reduce the period of the construction project by reason of owing design information jointly. This paper represents the design methodology of system integration using Business Process Reengineering by the case study. The case study is about the offshore plant material information process from front end engineering design to detail engineering for the construction and the basis of monitoring system by integrating and sharing the design information between the 2D intelligent P&ID and 3D plant modeling using relational database. As a result of the integrated data modeling and system integration, it is possible to maintain the consistency of design process in point of view of the material balancing and reduce the design assumption/duration. Near future, this system will be expanded and connected with the MRP(Material Requirement Planing) and the POR (Purchase Order Requisition) system.

The INS/GPS integration system is designed by employing an adaptive filter that can estimate the measurement noise variance using the residual of the filter. To verify the efficiency of the proposed loosely-coupled INS/GPS integration system, simulation is performed by assuming that GPS information has large position errors. Simulation results show that the proposed integration system with the adaptive filter is more effective in estimating the position and attitude errors than those with the Extended Kalman Filter.

RFID 기술은 기업으로 하여금 단품 수준에서의 의사 결정을 통한 정교한 재고 관리를 가능하게 한다. 최근 EPCglobal과 같은 RFID 정보 교환 표준이 보급됨에 따라 RFID 시스템은 RFID 하드웨어, 미들웨어, 정보 저장소로 구성된 정보 시스템으로 간주되고 있으며 이는 중요한 시스템 통합의 대상으로 부상하였다. 본 연구에서는 RFID 시스템과 기업정보시스템의 효과적인 연동을 위하여 연동 모델 선택 절차와 각 절차별 고려사항을 총 다섯 가지 단계로 구성한 RFID 시스템-기업정보시스템 연동 프레임워크를 제안하였다. 또한 국내 RFID 시스템과 기업정보시스템 연동 현황과 향후 적합한 연동 모델을 설문 조사를 통하여 제시하였다. 본 연구에서 제안한 연동 프레임워크와 설문 결과는 RFID 시스템을 처음 도입하는 기업이 RFID 시스템과 기업정보시스템을 효과적으로 통합할 수 있도록 기여할 것이다.

분산된 지역 데이타베이스의 스키마 통합시 중심 개념은 엔티티 통합을 의미하며 이때 엔티티의 시멘틱은 여러 요소에 영향을 받는다. 따라서 분산된 데이타베이스 환경에서의 스키마 통합은 통합되어야 하는 각 지역의 스키마의 엔티티 타입간의 도메 인 관계의 정의로부터 시작된다할 수 있다. 이렇게 설계자에 의해 정의되는 각 엔티티 간의 도메인 관계는 스키마 통합 시스템의 신뢰도의 확보와 검증을 위한 작업이 반드 시 수행되어야 한다. 그러나 이러한 작업이 기존의 통합 시스템에서는 제시되지 못하였다. 본 논문은 분산 시스템 환경에서 지역 데이타베이스의 스키마 통합을 위한 객체 중심의 통합을 정의하고, 통합의 타당성 검증을 위한 모델을 제안하고 검증 시 스템을 구현한다.

This paper proposes and implements a mobile service and web service integration for utilizing public bicycle sharing system NUBIJA. The NUBIJA system is operated by Changwon City, GyeongNam since 2008 and maintains 247 unattended bicycle sharing terminal on the city. Average users per day of the NUBIJA are more than 8,000 and many users want to get more services from their mobile phones. We implemented realtime mobile bicycle rental and return information service. The informations are acquired from each terminal kiosks and we integrated the information and location based services(LBS) on iOS and Android platform. In this paper, we described an integration services between web and mobile application and shows graphical user interface for highly customized on mobile platforms.

As growth of operational complexity in power systems, necessity of information integration between automation systems such as EMS, SAS, DAS and renewable energy sources has been increased. This paper proposes a new information integration architecture between power automation systems based on web service technique. Loosely coupled feature of web service system can provide more flexible and reliable way to exchange information. Communication testing on the demonstration system has been performed to establish the feasibility of the proposed architecture.

The application of computers and information technologies progressed with remarkable pace has paved the way for technological innovation toward the efficient integration of various functions in a manufacturing system. Actually it is observed that the greater part of manufacturing companies already initiated significant efforts to integrate information systems and attained the level of integration to some extent. The purpose of this paper is to clarify the strategic direction that manufacturing firms are pursuing through integrating information systems. Using the extensive data gathered from Japanese manufacturers, it is attempted to find the differences in competitive priorities and action programmes between the companies with high and low-level system integration. Our empirical data reveals that the manufacturers with highly integrated system are focusing their competitive capabilities on the rapid design change and new product introduction, and accordingly they place a greater emphasis on the action programmes related to design, process and quality improvement. As a conclusion, highly integrated firms tend to pursue new product development strategy more intensively, thereby they want to be a preemptor in the new market through exploiting technological advantages of integrated manufacturing system.

In order to overcome the problem that outdoor and indoor spatial information service are separately utilized, an integration service system of spatial information that is linked from outdoor to indoor has been implemented. As a result of the study, "0001.xml" corresponding to the file index key value, which is the service connection information in the building information of the destination, was extracted from the prototype verification of the system, the search word of 'Kim AB' was transmitted to the indoor map server and converted from the outdoor map service to the indoor map service through confirmation of the navigation service connected information, using service linkage information and search words of the indoor map service was confirmed that the route was displayed from the entrance of the building to the destination in the building through the linkage search DB (Database) table and the search query. Therefore, through this study was examined the possibility of linking indoor and outdoor DB through vector spatial information integration service system. The indoor map and the map engine were implemented based on the same vector map format as the outdoor map engine, it was confirmed that the connectivity of the map engine can be applied.
