Korea augmentation satellite system (KASS) is the Korean satellite based augmentation system (SBAS) developed by ministry of land, infrastructure, and transport (MOLIT) since 2014. Since KASS is the safety critical system that can affect to the safety of airplane, the software of KASS is developed according to the DO178B software level induced from safety analysis. In case of KASS control station (KCS), most of the software of KCS get assigned software level E in DO178B. In that case, ECSS-Q-ST-80C category D is assigned as a software product assurance standard. In this paper, the software related standard ECSS-E-ST-40C, ECSS-Q-HB-80-04A are analyzed to satisfy ECSS-Q-ST-80C and as a result the software product assurance activities regarding software life cycle and the software quality model, metric is proposed for the product assurance of the KCS software.

To date many software engineering cost models have been developed to predict cost, schedule, and effort of the software under development. The COCOMO Ⅱ is well- suited for the new software development life cycle such as non-sequential and rapid- development processes. The traditional regression approach based on the least square criterion is the most commonly used technique for empirical calibration in the COCOMO Ⅱ model. It has a few assumptions frequently violated by software engineering data sets. The source data is also generally imprecise in reporting size effort, and cost-driver ratings, particularly across different organizations. And that the outlier for the source data is a peculiarity and indicates a data point. To cope with difficulties, in this paper, we propose a new regression method for calibrating COCOMO Ⅱ post-architecture model based on the minimum relative error(MRE) criterion. The characteristic of the proposed method is insensitive to the extreme values of the data in the empirical calibration. As the experimental results, It is evident that our proposed calibration method MRE was shown to be superior to the traditional regression approach for model calibration, as illustrated by the values obtained for standard deviation(^σ), and prediction at level LPRED(L) measures.

The assurance of software product. which Is different to other products. is very complex because of Its characteristics. The use of objective development standards or guidelines and the confirmation to meet user's requirements are Important to achieve the software quality system. Moreover correct understanding of qualitv standards and continuous applications of check-points for qualify audit are necessary. ISO 9000 series. which are International standards. were made for the qualify assurance. Among them. ISO 9000-3 is the quality management and quality assurance standards for applying ISO 9001 to the design. development. supply. installation and maintenance of software. The newly revised ISO/CD 9000-3：1995 contains a lot of enforced changes within ISO 9001 framework - quality standards for manufactured products. This paper analyses the revised ISO 9000-3 by comparing it to ISO 9001. and derives quality audit points to use for qualify audit In future.

A non-functional requirement is a property or quality that the proposed systems have to support the functional requirements. A non-functional requirement is reflected by quality attribute These non-functional requirements playa crucial role during system development, serving as selection criteria for choosing among decisions. It should be continuously considered through the software development process. In spite of the importance of the non-functional requirements, it received little attention because of ambiguousness and invisibility of non-functional requirements. Therefore non-functional model which is a process to analyze the non-functional requirement is proposed for improving the management efficiency of non-functional requirements. Also, this paper presents the trace among the UML diagrams to the conceptual model. According to the non-functional requirement development process, this paper achieved performance-based case study. After then, non-functional requirement should be traced using the UML diagrams.

It is very important to trace whether all the requirements has been reflected in the developed system. However, most existing researches apply Requirement Traceability Matrix(RTM) to the whole SDLC according to the development methodology. RTM has no practical value because it has not only too many pursuit items but also its tracking method is very complicated and the practical management in developing the information system is not accomplished nearly. Therefore, in this study, we proposed an enhanced RTM which was composed of only necessary items and allow us to manage the applied area effectively from Request for Proposal(RFP) or the proposal stage to SDLC stage then confirmed the effect through six actual applicable cases of information system development project of "K" company.

The environment to development information system including a GIS has been drastically changed in recent years in the perspectives of the complexity and diversity of the software, and the distributed processing and network computing, etc. This leads the paradigm of the software development to the CBD(Component Based Development) based object-oriented technology. As an effort to support these movements, OGC has released the abstract and implementation standards to enable approaching to the service for heterogeneous geographic information processing. It is also common trend in domestic field to develop the GIS application based on the component technology for municipal governments. Therefore, it is imperative to adopt the component technology considering current movements, yet related research works have not been made. This research is to propose a component-based GIS development methodology-ATOM(Advanced Technology Of Methodology)-and to verify its adoptability through the case study. ATOM can be used as a methodology to develop component itself and enterprise GIS supporting the whole procedure for the software development life cycle based on conventional reusable component. ATOM defines stepwise development process comprising activities and work units of each process. Also, it provides input and output, standardized items and specs for the documentation, detailed instructions for the easy understanding of the development methodology. The major characteristics of ATOM would be the component-based development methodology considering numerous features of the GIS domain to generate a component with a simple function, the smallest size, and the maximum reusability. The case study to validate the adoptability of the ATOM showed that it proves to be a efficient tool for generating a component providing relatively systematic and detailed guidelines for the component development. Therefore, ATOM would lead to the promotion of the quality and the productivity for developing application GIS software and eventually contribute to the automatic production of the GIS software, the our final goal.

Several different approaches and mechanisms are introduced to solve the UAV path planning problem. In this paper, we designed and implemented an agent-based simulation software using the Repast platform and Java Genetic Algorithm Package to examine an evolutionary path planning method by implementing and testing within the Repast environment. The paper demonstrates the life-cycle of an agent-based simulation software engineering project while providing a documentation strategy that allows specifying autonomous, adaptive, and interactive software entities in a Multi-Agent System. The study demonstrates how evolutionary path planning can be introduced to improve cognitive agent capabilities within an agent-based simulation environment.

최근 많은 중소기업이 자사의 경쟁력 확보, 업무혁신, 원가절감 등의 이유로 ERP의 필요성을 인지하고 ERP 도입을 추진하고 있다. 그러나 기존의 ERP 구축 방법론들은 대기업의 ERP 도입에 맞추어 개발되었기 때문에 중소기업이 이를 적용하기 위해서는 많은 문제점의 극복과 기술력을 필요로 한다. 중소기업이 성공적으로 ERP를 도입하기 위해서는 중소기업에 특성화된 ERP 구축 방법론이 필요하며, 이에 따라 본 논문에서는 ISO 12207 소프트웨어 생명주기 프로세스의 활동을 조정한 중소기업을 위한 ERP 구축 프로세스를 제시한다. 제시한 구축 프로세스는 ISO 12207을 기반으로 하며 ERP 패키지 도입에 따르는 고비용 부담, 전문인력 부족, 경영자 및 종업원의 ERP 도입에 대한 적극적 의식 결여, ERP 도입의 거부감 등 중소기업이 ERP를 도입할 때 발생할 수 있는 문제를 해결하기 위한 활동이 추가되었다.

정보화가 기업 경쟁력의 핵심 요소로 부각되고 있으며 기업 및 정부기관은 앞 다투어 정보화에 투자하고 있는 상황이다. 정보시스템 개발 프로젝트도 이제는 대형 프로젝트 수가 급증하고 있다. 최근 소프트웨어 CMMi 수준에 관한 인증 여부는 기업 경쟁력의 핵심적인 요인으로 그 중요성이 날로 강조되고 있다. 또한 PMI의 PMBOK는 프로젝트 관리의 바이블 격으로 업종 업태를 불문하고 광범위하게 적용되고 있는 상황이다. 프로젝트 관리자의 관점에서 볼 경우 CMMi 모델과 PMBOK 모델간의 중첩되는 부분, CMMi 프로세스를 실적용 시 관리영역에 대한 혼선 부분, 또한 PMBOK 상위지침의 구체성 미흡 부분에 대한 통합 및 조정이 필요하게 되었다. 현재 상용되는 개발방법론에는 관리적인 요소가 매우 미약하고, 국내에 아직까지 체계적으로 정립된 관리방법론이 없는 상황이다. 따라서, 본 논문에서는 프로젝트 관리자가 숙지해야 하는 프로젝트 관리영역, 프로젝트 관리단계, 제반 절차, 유관 정보시스템과의 연동(Interface) 등을 정보화 개발 프로젝트 생명주기(Life Cycle)에 맞춰 재구성 및 통합하여 프로젝트 관리자(Project Manager)에게 일관된 관점(Single Point of View)을 제시하여 프로젝트 생산성을 제고 하고자 한다.
