As component-based development (CBD) rapidly spread throughout the software industry, a comprehensive methodology is needed to apply it more systematically. For this purpose, a new CBD methodology named Magic & Robust Methodology Integrated III (MaRMI-III) has been developed. The purpose of this paper is to present MaRMI-III by its constituent processes and claim that it can be used to support system developers conduct CBD in a consistent manner. First, we review the CBD approach to system development and the role of CBD methodology, and then we explain the several characteristics of MaRMI-III which are considered necessary to the CBD environment. Next, we explain a process model of MaRMI-III which separates the development process from the project management process and prescribes well-ordered activities and tasks that the developer should conduct. Each phase forming the Process Model is explained in terms of its objectives and main constituent activities. Some techniques and workproducts related to each phase are also explained. Finally, to examine the usefulness of MaRMI-III, an analytical comparison with other CBD methodologies and the results of a questionnaire survey are described.

본 연구에서는 기업에서 서비스 상품의 개발 프로세스를 수행하는 과정에서 서비스 설계에 적용되는 서비스 컨셉의 개념을 고찰하였다. 서비스 컨셉은 전략적인 새로운 서비스 개발이나 서비스의 리모델링 작업 등의 계획 단계에서 의사결정에 관하여 중요한 역할을 하게 된다. 특히 다양한 서비스 요소들의 결합을 통해서 서비스전달시스템의 최적화된 운영계획을 수립하거나 또는 서비스 회복 등을 다루는데도 유용한 개념이며, 서비스 컨셉의 결과를 통해서 개발대상 서비스 상품에 대한 고객의 수용성과 비즈니스 모델로서의 성공가능성을 평가하는데 중요하다. 따라서 본 연구에서는 서비스 개발의 전반적인 과정에서 서비스 컨셉을 적용하는 모델과, 설계과정에서의 서비스 컨셉을 평가할 수 있는 모형을 제시하였다.

UML은 용용시스템 또는 컴포넌트 개발과정에서 분석 및 설계과정을 모델링하여주는 표준언어이며, CORBA, COM+, EJB 등은 컴포넌트의 재사용을 실현화시켜주는 기술이다. 컴포넌트 개발과정에서 재사용가능한 컴포넌트와 새로 개발할 컴포넌트를 구별한 후 개발하면, 응용시스템이나 컴포넌트의 개발비용을 줄일 수 있고, 질이 좋은 컴포넌트를 생성할 수 있다. 본 논문에서는 컴포넌트의 개발과정에서 생성되는 산출물들의 모델링시에 필요로 하는 컴포넌트 속성에 따르는 확장된 UML 표기법을 정의한다. 또한, 사례 연구로 특정 영역인 웹상의 경매 시스템 개발에 필요한 컴포넌트들의 모델링 및 UML 적용기법을 소개한다.

The defense M&S system, which has been classified as a weapon system between requirements determination and project implementation, is being developed by applying the weapon system development procedure of the Defense Acquisition Program Administration. The M&S system abstracts and models the real world to suit the intended use and proceeds with the process of developing it as a software-oriented system. Overseas, the conceptual model development stage is staged before entering the design stage after the requirements analysis. In addition, each step includes verification and validation processes. In Korea, while establishing and applying the weapon system development procedure based on the SE process, the M&S system is also applied in the same way as the general weapon system, limiting appropriate development outputs and verification and validation. In this study, the system development procedure of the M&S system is established and presented based on the relevant standards and SE process of developed countries.

In this paper, we suggest a quantitative management scheme to accomplish effective weapon systems test and evaluation service(T&E). The Capability Maturity Model Integration(CMMI) process model has been introduced and applied for that purpose by the 8th directorate, Agency for Defense Development(ADD). Although a CMMI process model was developed focusing on the software development, systematic approaching scheme in the CMMI process model can be utilized for the quantitative management implementation of a weapon systems T&E service. To manage a T&E service quantitatively, at first, organizational performance objectives and sub processes are established, and then each performance indicators and performance base lines are followed.

For the success of system development, it is necessary to systematically manage the requirements that are the basis of system development and its verification results. In order to follow the principles of SE(Systems Engineering)-based V&V(Verification&Validation) process, requirements can be managed by securing the requirements and their establishments, design compliances, and verification compliances according to the system development lifecycle. Especially, in a large-complex system research and development project, such as a space launch vehicle development project, many participants establish, verify, and validate numerous requirements together during the project. Therefore, logical and systematic requirements management, including guarantee of data integrity, change history, and traceability, is very important for multiple participants to utilize numerous requirements together without errors. This paper introduces the practical requirements and verification management for the requirements-based development process in the space launch vehicle development project.

The target of this paper is the development of Web-based monitoring & control system which is for effective and economic management of mold manufacturing process. This system has three module; G-code Control, Monitoring Module and Result analysis module. Also, as the environment of development is based on internet, this system which is possible to the remote site management of manufacturing process works on Web. To be possible to control the manufacturing monitoring by client, each module is made ActiveX control and is based on socket communication. This system makes the foundation which is possible to manage the mold manufacturing process efficiently from remote site by matching real-time monitoring with manufacturing process in factory using G-code control and displaying the result of manufacturing using Ch-CGI.

Systems engineering is being applied to various fields of industry such as national defense, aerospace, transportation, railway, and information technology industries. But in Korea, systems engineering has been selectively applied to government-driven projects such as space rocket development projects and unmanned flight development projects. And systems engineering processes introduced from international systems engineering standards has been directly applied to those projects. Unfortunately, this application method is not recommended as it requires highly experienced systems engineers. From our previous paper, we have proposed that domain specific engineering standards should be developed to be used as references for development of organizational engineering guide, so that more successful engineering performances can be achieved. And in this paper we have proposed a refinement of systems engineering processes from international systems engineering standards as they are bases of domain specific engineering standards.

In the automotive industry, TWB hot stamping process is broadly adapted to reduce weight of the car and improve fuel efficiency. However, the process faces a problem of weakened strength of the welded zone after hot stamping process, due to the fact that Al-Si elements of the coating layer penetrating the welded zone. In this study, filler wires with high percentages of carbon and manganese is adapted during laser welding process to secure the strength of the fusion zone. In addition, wire feeding speed and laser welding speed are optimized by sample test.
