무기체계 개발에 있어서 내장형 소프트웨어의 비중과 그 중요도가 점점 증가하고 있고, 고객 또한 무기체계 소프트웨어 개발 및 관리지침을 제정하여 소프트웨어 신뢰성 시험수준에 대한 놓은 요구사항을 제시하고 있다. 이렇게 대내외 환경이 변화하고 있음에 따라 당사는 고품질의 소프트웨어를 고객에게 납품하기 위해서 내장형 소프트웨어 신뢰성 향상활동을 수년간 수행해오고 있다. 업체주관 개발사업 증가와 무기체계 외주개발 비중 증가에 따라 고품질의 협력개발 소프트웨어의 획득이 중요해지고 있다. 하지만, 납품 받은 소프트웨어를 체계 통합하는 시기에 소프트웨어 결함이 많이 내재되어 있어 문제점이 많이 발생되고 있으며, 납품 이후에도 많은 결함수정과 재 작업이 발생하여 추가비용이 많이 발생하고 있다. 본 논문에서는 협력개발 소프트웨어 제품의 신뢰성 향상을 위해 TMMi 시험 프로세스를 적용하여 협력회사의 소프트웨어 시험 역량을 강화하고 고품질의 소프트웨어를 획득할 수 있는 방안을 제안하고자 한다.

Service-oriented architecture(SOA) is a paradigm where reusable units are independently executable and only accessible through outer interfaces. Standardized methodology based on SOA has not been decided yet although a lot of efforts have been made for systems using SOA. Therefore Development of system using SOA is facing many difficulties currently. In this paper, service oriented methodology of function based model for supporting legacy system is proposed. Standardized methods for function based reusability through analysing SOA methodology are proposed and guide lines for improvement of service reusability are presented.

We propose the software framework construction method that increases reusability through use case extraction and structuring of software system's dynamic behavior of which identifying behavior patterns from software domain models. Most behavior models do not provide a consistent modeling technique for harmonizing user's heterogeneous requirements, and not yet prepared to a detailed optimizing technique for redevelopment and maintenance. Therefore, we need a software reuse framework to support consistency and reusability of existing development models using use cases with functional characteristics. a lattice model is used to this approach for structuring use cases, and the reuse process that can be driven to reusable components is introduced in this paper,.

In urban planning, road facility is used not only for the transportation purpose but also for the utility line space purpose such as electrical, gas, tele communication, heating, water, sewer, and so on. However, since these utilities are built by many different groups, it becomes very difficult to communicate each other. Delay in one party can cause another party's schedule delay but they don't commuicate often. Also, some delay in utility work can cause frequent pavement cut. And, this will impact on construction cost, schedule delay, low quality, user complain and cost. This study developed spatiotemporal decision model to prevent prequent utility cut for mega project such as new urban development project. In addition, this study developed utility cut management system to manage utility cut schedule under pavement. Finally, developed system was applied to new urban development project and verified there effectiveness.

Product Line Engineering (PLE) consists of two phases; Core Assets Development and Application Engineering. The core asset development is to model common features of members in a domain and to develop them. The application engineering is to effectively generate an application by instantiating the core asset. Today, PLE research mainly focuses on developing core assets, whereas activities and instructions for application engineering are weakly defined. Moreover, instructions of application engineering are not enough to be practically applied. To widely apply PLE to industry, researches on systematic and practical methods such as instantiation processes, instructions, and artifacts are needed. In this paper, we propose a practical PLE process, instructions, and artifacts about each activity. And then, we also present a case study to show applicability and practicality of the process proposed in this paper.

New game softwares usually have much similarities with old one in the sense of properties and procedures. But nevertheless, the development could be duplicated several times without referencing or reusing of others. In addition, because there is no standardized process about the game engine, the products generated by other software development processes are difficult to understand and to reuse. Therefore, the enterprise developing new game software newly analyze and design although it is same process as the old one. This paper proposes the improved process of the game engine, analysis of structures and relations, classification of the class and the module and their combination methods, implementation of storage, and processor model to apply the component based development method to the game engine.

As a technique to enhance reusability for the created artifacts in software modeling process, the model driven method such like MDA has been applied. Unfortunately, the hierarchical and systematic MDA based development technique using UML is poor yet. This causes the problem that the MDA modeling with high consistency and reusability based on MDA metamodel is not being realized. To solve this problem, this paper proposes a MDA (PIM/PSM) component modeling technique using 2+1 view integrated metamodel. At first, the meta-architecture view model which can represents development process view and MVC view is defined. Then, the hierarchical integrated metamodels per view are addressed separately for modeling process and MVC at metamodel level on the hierarchy of the defined meta-architecture view model. These metamodels are defined hierarchically by layering the modeling elements in PIM and PSM pattern for UML models and GUI models. Appling the proposed metamodel to an ISMS application system, it is shown as a component modeling case study based on MDA. Through this approach, we are able to perform a component model with consistency and hierarchy corresponding to development process and MVC way. Accordingly, this may improve more independence and reusability of model.

Recently, according to the rapid development of web technology, a lot of applications based on web techniques have been developed. However, most of web applications have been developed relying on knowledge and experiences of the developer without systematic process. Web Applications are seldom developed in isolation. For web application designers, the simple and semantically rich methodology is needed to improve design and development process. In this paper, we propose a new development process methodology to improve low level technology based application development process which do not provide high level abstraction. We also suggest a new methodology to construct applications based on web. We describe a systematic web application development process by using Navigation Diagram as a analysis, design modeling method to develop web application with productivity and Quality. We apply the new development process to the EPBS(Electronic Problem Bank System) as examples. Web application development process proposed in this thesis can be maintained through reverse development, because it can be defined as high level abstraction for modeling. It is very easy to be understood as a process based on models. Also, analysis and design models can be reused as useful component whenever similar web application is developed.

In Korea, National spatial data infrastructure has implemented in order to integrated manage and share the national spatial information producted by public agencies and local governments. The necessities of systematic quality management are raised, because information, which is generated by different agencies, is integrative managed by national level. In this paper, the establishment of BPR(Business Process Reengineering) for national spatial data infrastructure quality management system. Quality management business is defined as quality management object definition, quality measuring, evaluation and analysis, and quality enhancement process. Next, activities for each process are designed. For the quality management business, business rule(BR) is required for determining error. We derive the BR for six objects(legal-dong, railway boundary, railway centerline, road boundary, road centerline, building) among the basic spatial information. Other information's BR can be generated by using the derivation method described in this paper. Based on the BPR of this paper and derived BR, national spatial data infrastructure quality management system can be implemented in the future.
