Today, the scale of the computer software market has increased, and massive sized software has been developed to satisfy diverse requirements. In this context, software complexity is increasing and the quality of software is becoming more difficult to manage. In particular, software reuse is important for the improvement of the environments of legacy systems and new system development. In this paper, we propose a method to reuse modules that are certified by quality. Reusable levels are divided into code area (method, class, and component), project domain, and business levels. Based on the coupling and cohesion of software complexity, we propose a reusable module extraction mechanism with reusability metrics, which constructs a visualization of the "reusable module's chunk" based on the method and class levels. By applying reverse engineering to legacy projects, it is possible to identify reusable modules/objects/chunks. If these modules/objects/chunks are to be reused to develop an extension system or similar new system, we need to ensure software reliability in order to reduce the time and cost of software development.

When the developers develop the software, the cost and time of the software development can be reduced by using blocks that are implemented previously. We call these implemented blocks components. In the early stage of Web-based Instruction, it didn't gain preference in spite of it's benefit of convenience. The main reason is, I think, the lack of generality at the education system which eventually results in unsatisfactory facilities compared with the requirement of teachers and students. And the early systems don't make good use of the plenty data in distributed environment, and don't show so good reliablity due to lack of systematic design and development. In this paper, we suggest WBI developing technology using the concept of WBSE. WBI developing is consist of component of pre-developed education software, integration of component using its reusability, and production of more requirement-satisfactory education software.

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.

Recently, the development paradigm of enterprise information system has been moved from 2-tier environment to 3-tier environment. 3-tier environment makes possible to develop more efficient system in terms of the performance, extension, deployment and maintenance. The ship drawing process management system which manages a long-term drawing process and a great number of designers has to support an accuracy and a real-time of information but it is impossible because it is still served in 2-tier environment and some process of them is not developed yet. In this paper, we implemented the analysis and design of system based on CBD(Component Based Development) for the purpose of hanging the environment from two-dimensional Client/server architecture environment to COM＋ based 3-tier architecture environment. And by completing a development of total system, the productivity and the efficiency of the ship drawing process management system will be improved. And a wide reuse of components makes possible to improve the productivity and efficiency of system.

Along with shortening the life cycle of software utilization and supporting various types of user functions, the importance of software architecture development has been emphasized recently. If a software architecture is developed flexibly and reliably for expansion to support new functionality, it can quickly cope with new market demands. This paper proposes an architecture design method based on design recovery of open source software to reuse the software in the development of sustainable software system. When using open source software to develop a software system based on software architecture, we can develop a software system rapidly and also can improve the reliability of the system because we use the already proven open source software in the development.

Many researches have achieved to reuse existent experience at each step of software life cycle. It is achieved various study about Design Pattern serving that abstract level solves design problem at high level. But, design step is not supplying design information that is abstracted so that new designers may reuse standardizing defined good design information. Therefore, in this paper, to do so that can reuse existent design information because composes Design Pattern can solve problem at design step, and extend design information that also is standardized XMI to base meta model of Design Pattern. And I did so that can compose Design Pattern utilizing MetaModel of Design Pattern standardized by XMI. Therefore, software designer can reuse composing existent design information that is could standardize problem at design because uses MetaData of standardized Design Pattern, and designs by Design Pattern base.

Recently, distributed collaborative development environment has been recognized an alternative environment for product development in which multidisciplinary participants are naturally involving. Reuse of Product design information has long been recognized as one of core requirements for efficient product development. This paper addresses an image-based retrieval system to support product design information reuse. In the system, product images obtained from multi-modal devices are utilized to reuse design information. The proposed system conducts the segmentation of a product image by using a labeling method and generates an attributed relational graph (ARG) that represents properties of segmented regions and their relationships. The generated ARG is extended by integrating corresponding part/assembly information. In this manner, the reuse of assembly design information using a product image has been realized. The main advantages of the presented system are following. First, the system is not dependent to specific design tools, because it utilizes multimedia images that can be obtained easily from peripheral devices. Second ratio-based features extracted from images enable image retrievals that contain various sizes of parts. Third, the system has shown outstanding search performance, because we applied various information of segmented part regions and their relationships between parts.

Reusing IPs requires interface protocol related tasks such as writing test benches and designing interface protocol conversion circuits, e.g. wrappers for IPs. The results of those tasks usually include IPC(interface protocol component)s for the corresponding IPs, similar to bus protocol components of the bus functional models. This paper proposes a methodology for the interface circuit design using synthesizable In that can be re-used. IPC recognizes or executes transactions over the given interface ports. So we present a transaction-oriented interface protocol description language, and a method to convert the description into an IPC in synthesizable VHDL code. With experiments, we show that the interface design using IPC does not cause significant area overhead compared with the interface design without IPC. The proposed IPC-based approach can be employed to reduce the interface design time since the designers can reuse IPCs without understanding the detailed interface protocols.

Component Based Development (CBD) is appealing as a technology to improve the productivity of software development through component reuse. Model Driven Architecture (MDA) is a new development paradigm which automatically generates application by transforming design models incrementally. Since both reusability of CBD and model transformation of MDA increase software productivity. integration of two technologies is desirable. To enable this technology integration, we need to devise a UML profile for specifying component design as a PIM. In this paper, we first define a meta-model for components, and propose a UML profile which is used to specify elements of component design as PIM. Since the proposed profile is based on Meta Object Facility (MOF) from which is MDA is derived, it is consistent and compatible with existing MDA methods and tools.
