This paper presents requirements for workflow management systems supporting CITIS. We propose an architecture of global workflow management system which aims at supporting external workflow among different organizations rather than internal one. The architecture consists of five key elements, that is process definition language, process graphic design tool, control engine, status monitoring tool, and interface models. For each of these elements, implementation requirements are presented and its major functions are described. A key concept to the CITIS standard is the integration of disparate systems in distributed environment. This leads us to place a special emphasis on the interface models that can enhance the interoperability between externally participating workflow systems. Two interface models for the global workflow management system are explained. CORBA, the most widely accepted standard for distributed object management, can be adopted to facilitate the integration. World Wide Web can be used for the underlying platform on which information is exchanged and the status of processes instances is monitored. The workflow management system can provide a ready and easy access to and management of the data for CALS environments.

In this study, a demolition analysis code using the adaptively shifted integration (ASI)-Gauss technique, which describes structural member fracture by shifting the numerical integration point to an appropriate position and simultaneously releasing the sectional forces in the element, is developed. The code was verified and validated by comparing the predicted results with those of several experiments. A demolition planning tool utilizing the concept of a key element index, which explicitly indicates the contribution of each structural column to the vertical load capacity of the structure, is also develped. Two methods of selecting specific columns to efficiently demolish the whole structure are demonstrated: selecting the columns from the largest index value and from the smallest index value. The demolition results are confirmed numerically by conducting collapse analyses using the ASI-Gauss technique. The numerical results suggest that to achieve a successful demolition, a group of columns with the largest key element index values should be selected when explosives are ignited in a simultaneous blast, whereas those with the smallest should be selected when explosives are ignited in a sequence, with a final blast set on a column with large index value.

Purpose: This study aims to improve the evaluation system for selecting supportive housing applicants, addressing inconsistency, lack of health and care evaluation, and the need for a quantitative evaluation tool. Proposed improvements include a consistent evaluation index and items for each resident type, selecting suitable residents for independent living and community integration. Research design, data and methodology: This study analyzed the supportive housing selection checklist provided by the Seoul Metropolitan Government, the supportive housing ordinance, and the SH Corporation's operation guidelines. Results: Study finds current supportive housing tenant selection system lacks consistency and proposes improvements. The same terms should be used for the same evaluation items, health and care evaluation items should be added for all tenants, and a quantitative evaluation tool should be used. Consistent evaluation index and items should be created for each resident type in the same evaluation area. The aim is to select suitable tenants with potential for independent living and community integration. Conclusions: This study improves the evaluation system for selecting supportive housing applicants by addressing inconsistencies and adding essential evaluation items related to health and care. While the study is significant, future research should focus on developing quantitative evaluation tools for all detailed items.

JBI(Java Business Integration)기반의 ESB(Enterprise Service Bus)는 웹서비스표준으로 서비스의 유통경로를 구현한 SOA(Service Oriented Architecture)의 한 방법이다. 광범위한 벤더로 구성된 JBI기반의 ESB는 서비스를 플러그인 할 수 있는 확장성의 장점을 가지고 있지만 사용자가 서비스유닛을 사용하기 위해선 복잡한 절차의 패키징과정을 수동으로 연동해야 하고, 순차적인 절차를 따른 배포방법을 사용해야 하는 비효율적 유지관리의 문제점을 가지고 있다. 본 논문에서는 이러한 문제를 해결하기 위해 컴포넌트간의 연동을 위한 모델링에서 배포의 전 과정을 통합하여 관리할 수 있는 사용자 중심의 컴포넌트 배치도구를 설계 및 구현하였다. 배치도구의 설계를 위해 첫째, 기존 JBI를 지원하는 배치도구를 분석하여 문제점 및 개선사항을 도출하였다. 둘째, JBI 기반의 ESB에서 가지고 있는 문제점 등을 기반으로 요구사항을 도출해 내었다. 그리고 최종적으로 JBI를 지원하는 컴포넌트의 스키마를 분석을 통한 모델링의 속성 및 패키징, 배포, 검증 기능을 설계하고 구현하였다. 본 논문에서 제안하는 도구를 이용하면 사용자는 컴포넌트의 연동을 위한 모델링에서 배포의 전 과정을 별도의 도구와 수작업 없이 배치도구 내에서 통합적으로 수행하고 관리할 수 있으며 GUI기반의 컴포넌트 모델링과 관리를 통하여 사용자는 사용성과 편리성을 높일 수 있다. 또한 컴포넌트의 유효성검증 및 경로에 대한 유효성검증을 통하여 서비스유닛을 배포하는데 발생 할 수 있는 오류를 최소화 할 수 있을 것으로 기대된다.

Satellite and aerial remote sensing (RS) techniques have been provided to collect spatial data globally over the last few decades. However in developing countries such as China, there is still an urgent need for low cost and high resolution RS data. As an emerging RS platform, commercial Unmanned Aerial Vehicle (UAV) integrated with state-of-the-art sensors and information technologies has the potential to become a low cost tool to meet application demands. In this paper, the architecture of UAV RS operation system is mentioned. Moreover, key technologies in UAV RS system are analyzed and current work is reported.

Integration of wind generators with the conventional power plants will raise operational challenges to the electric power utilities due to the uncertainty of wind availability. Thus, the Generation Scheduling (GS) among the online generating units has become crucial. This process can be formulated mathematically as an optimization problem. The GS problem of wind integrated power system is inherently complex because the formulation involves non-linear operational characteristics of generating units, system and operational constraints. As the robust tool is viable to address the chosen problem, the modern bio-inspired algorithm namely, Grey Wolf Optimization (GWO) algorithm is chosen as the main optimization tool. The intended algorithm is implemented on the standard test systems and the attained numerical results are compared with the earlier reports. The comparison clearly indicates the intended tool is robust and a promising alternative for solving GS problems.

This study investigated the needs and effectiveness of the application of Computer-Aided Systems Engineering Tool in order to enhance the chance of success of the large and complex system development projects like City Train System. Furthermore, it was shown that the merits of Systems Engineering and Project Management must be complementary to each other in their interaction in a project. Especially, for the project plans must be executed based on the fully understood system being developed, the technical and management data of the system development need be integrated and be able to support exact and rapid decision making of project planning. As an alternative solution approach, a model for development knowledge capture integrating both technical and management data of system development was proposed using Computer Aided Systems Engineering tool-Cradle.

In order to provide continuous Korea Augmentation Satellite System (KASS) services, the operation organization should continuously and systematically perform operations, maintenance, and technical activities. All subsystems of KASS, all Line Replacement Units (LRUs), and Software Replacement Units (SWRUs) should be operated and maintained continuously. In order to effectively manage these activities, it is necessary to develop an Operation Management Tool (OMT). For this purpose, operation management, operation organization, and operation activities were defined. The defined requirements were divided into general, function, interface, and database for OMT development, and functions and decision-making procedures consisting of site/asset/trouble/work order/schedule management were designed. The OMT developed by reflecting the site and asset information as well as the design content met predefined requirements. The OMT will be actively used in actual KASS operation and will evolve by continuously reflecting the additional requirements of operators. Through this tool, KASS will support continuous service provision.
