Recently, there have been a lot of works trying to realize automated composition of semantic web services though application of AI planning techniques. The traditional AI planning techniques, however, have some limitations: it is not easy to represent a web service process with complex control constructs as an action or a plan; it is hardly possible to consider enough the rich information contained in domain ontologies during the planning process; it is impossible to model directly the data flow from the outputs of a web service to the inputs of another web service; it is difficult to predict and deal with uncertainty and dynamics of the environment because the plan generation phase is supposed to be separated from the plan execution phase. In order to overcome some of these limitations, this paper suggests a reactive planning approach to automated composition of semantic web services. Through some experiments using several e-commerce web services, we found that the reactive planning is an effective way to realize automated composition of semantic web services.

The present thesis is to concretize process stages and methods for effective use of online CGTS(creative group thinking system), or the web-storming program, in space design and to propose a support system for idea generation specific to space design. For the purpose of this study, activity factors in space design process and functional factors of the web-storming program were written into an interaction matrix, which was used for a questionnaire survey on correlations. Then, the results of the interaction matrix were visualized and analyzed following the procedure of observation-interpretation-application. The analysis found that the schematic design stage is most correlated where close collaboration is performed in the process of space design and that differences in correlation arise upon division of work. As such, the present study proposed 'provision of media for ideas in accordance with specific process and UI optimization' as a means of improving usability in schematic design that is closely correlated and suggested an idea to enhance the applicability of web-storming system in division of work.

Production planning is one of the most important activities in shipbuilding enterprises. Shop-floor supervisors and planners still do not have enough information to effectively analyze shop operations because of the difference between production planning and shop-floor scheduling. In this paper, process analysis was conducted between production planning and shop-floor control to clarify the difference, and the necessity of the manufacturing execution system(MES) was derived in a shipyard. Therefore, the simulation-based ship production execution system(SPEXS) was defined by analyzing characteristics of MES. The architectural functions of the system were deducted from the process of requirement analysis. The SPEXS' framework was constructed on the basis of the architectural functions. This framework will provide more reliable production schedules and allow engineers to plan and control shop operations in real-time.

소프트웨어 품질에 대한 관심이 증가하면서 품질을 측정하고, 평가, 개선하기 위한 테스트 프로세스에 대한 필요성이 대두했다. 현재, IEEE/Std 829-1983, SEI 의 CMM, DoD 의 MIL-STD-498, ANSI/IEEE 의 SVVP등 테스트 프로세스에 대한 여러 국제적 지침이 많이 있지만 그 수준이 너무 일반적이고 개괄적이어서 실제 소프트웨어 개발에 적용되기엔 어려움이 있다. 본 논문에서는 IEEE/Std 829-1983 과 현재 국내 A 대기업에서 실시되고 있는 테스트 프로세스를 소개하고 이들을 조사, 비교 분석해 실제 소프트웨어 개발에 적용할 수 있는 품질 관리 계획 내 포함될 수 있는 엔터프라이즈 테스트 프로세스(Enterprise Test Process)를 제안한다.

X-Forms 기반의 웹 UI(User Interface)를 개발하는 소프트웨어는 개발이 완료되어 운영되는 과정에도 사용자의요구, 성능향상, 기능개선, 기능추가 등의 이유로 변경이 가능하다. 이러한 소프트웨어의 유지보수도 일반적인 요구사항명세, 분석, 설계, 구현의 개발 프로세스를 따른다. 본 논문에서는 UI 개발 소프트웨어의 유지보수 단계에서 효율적인 테스트를 하기 위해 V-모델을 확장, 변형한 테스트 프로세스 제안한다. 제안한 테스트 프로세스의 주요 활동은 요구사항분석을 통한 테스트 계획, 테스트 데이터를 식별하고 환경을 구축하는 분석과 설계, 테스트 케이스를 명세화하고 테스팅 방법론을 적용하는 구현과 실현, 리포팅과 산출물을 정리하는 테스트 마감 활동으로 진행한다. 웹 UI 개발 소프트웨어의 특징에 맡게 테스트 프로세스를 구축하고 실무에 적용하여 에러 검출률, 테스트 시간, 테스트 결과의 효율성을 높일 수 있는 방법을 제안한다.

많은 6시그마 혁신을 하는 기업 중에서 ISO9000 시리즈나 ISO/TS16949 인증을 받고 있다. 그럼에도 불구하고 6시그마 도입 초기부터 ISO/TS16949와 통합운영을 생각하고 추진하는 곳은 많지 않다. ISO/TS16949에서는 기업전반의 프로세스에 많은 중점을 두고 있다. 그 중에서도 APQP(Advanced Product Quality Planning)은 제품 초기에서부터 명확한 품질계획 업무 프로세스를 가지고 활동을 하라는 필수 프로세스를 요구하고 있다. 그러나 구체적인 Flow나 단계는 각 기업체의 특성에 맞기고 있다. 6시그마의 Lean DFSS는 이러한 제품개발 프로세스의 구체적인 전계단계를 제공하고 있다 여기에 APQP에서 요건으로 명시한 각 프로세스 단계마다 Input요소, Output요소, Target, 그 프로세스를 책임질 구성원, 핵심성공요인, 핵심성공지수, 단계마다의 FMEA(Failure Mode Effect Analysis) 분석을 대응하면 도입 초기에서부터 상호 유기적이면서 효과적인 System이 된다.

The purpose of this study is to present a systemized flow of temporary facility(TF) planning information. The current TF planning tends to be established by subjective decision making of field workers. Therefore TF planning needs more systemized information flow to provide a reliable schedule. The study was implemented through interview with experts for reliable TF planning. The main contents of the study are as follows; 1) TF planning process model(IDEF0) are established. 2) Various information flow diagrams proposed to support TF planning decision-making. The study recommends that, as a future research, the computer system be developed for application of the information flow.
