  • Medium size rotorcraft consist of approximately 5,000 key components. The components must satisfy the target weight and performance requirement through optimization. Therefore a rotorcraft component has approximately 100 times higher unit cost for mass production than the equivalent of an automobile's, along with huge development cost. Configuration management consists of four main parts : configuration identification, configuration control, configuration audit, and data management. In development programme, configuration management is one of the methods to save development cost, and setting a well-structured configuration management system according to the Military Standard is an important factor in success of the programme. The paper proposes a configuration management system suitable for development of various multi-use components development and presents that the configuration management was performed successfully during dual-use component development programme using the established system.

  • A version control system is used in a rapidly changed environment or a program which developed in a complicated environment. And configuration thread information supporting and it's processing method has an important part in version control. Configuration thread tool such as a system model of DSEE, a view of ClearCase, a label of SourceSafe, and the package of CCC/Harvest have applied to formalized configuration rule by user and obtained a desired configuration information of the version. But it is a problem of configuration thread in supporting information that we. in this method. can't know a exactly well-defined configuration rule information and a predefined information. And these information have a demerit that can't supported the close connection along with undefined version and a meta-information. In this paper. we have modeling a system for these problems to solve and a efficiently configuration thread supported. We also proposed a mixed retrieval model included a boolean retrieval model and a vector retrieval model for support efficiently configuration thread information. We applied and designed the libraries using extended facet method.

  • Configuration management is an important project management method. Configuration management is increasing daily and improving defense power as a management tool for technical data of power support systems. Configuration management work must be carried out properly from the beginning of development to acquire an excellent weapon system. In procurement, configuration management is a vital factor that can determine the cost of maintaining operations during the transfer of military supplies and carry out systematic management among operational support. Countries are making changes to policies and systems to manage R&D, standards, and patents in conjunction with each other from the beginning of research and execution, and it is important to establish the concept of managing and controlling the configuration as an efficient means of managing military resources. To identify the activity details during the entire life cycle from the beginning of acquisition to the end of disposal by linking munitions configuration control with the total life cycle, and redefine the appropriate work system, this study investigated and analyzed the U.S. configuration control procedures to identify the activity details and present areas to develop.

  • Software configuration management is a field of managing sets of large scale software outputs to be the basis of the software products. Configuration management has significantly improved for the past few years, yet new system is still required. Instead of using previous methods or researching about configuration management, professional management of developing project is needed. Therefore, techniques such as storage model for configuration management, management program for change procedure and management of program interface is needed. In this paper, we provide storage for configuration management and implement decision-making system to manage divided program and interface. Thus, we propose a new access method by the configuration management dependency. This paper provides configuration management for developing software to verify and classify using decision-making system for the change and combination of independent components with high dependency.

  • The waterjet is very widely used today in propulsion system of high speed vessel but manufacturer is limited because of an efficiency and a difficulty of a manufacture on the inlet configuration of the waterjet. The importancy in designing the inlet configuration of the waterjet lies on the minimization of the cavitation which is largely affecting the efficiency. In this paper, the configuration analysis is carried out to find a optimum shape which is minimizing the cavitation using a two dimensional potential-based panel method with an inlet configuration of a flush type. Also, it is developed a direct design method finding an inlet configuration by a given pressure distributions. The numerically obtained optimum shape using this configuration analysis method show a good agreement compared to the Kashiwadani's results. It is carried out a direct design method over a lip and a ramp of an inlet configuration wish pressure distributions obtained a result of the configuration analysis and the results show a good agreement compared to original configuration.

  • The ability to trace change history and dependency relations of software artifacts which are continuously changed has been recognized as an important factor that support quality management activities such as verification, validation, and testing in software system development process. General software configuration management systems provide tracing information for artifacts only within the configuration management system, and it does not go further to changes that occur within personal workspace. This paper provides a solution that helps tracing down not only changes of configuration items but also change history of artifacts existent in personal workspace through the integration of configuration management system and personal workspace. Furthermore, in cases of artifacts which are included in a configuration item, this paper provides a solution that support tracing dependency relations between the artifacts by identifying their version links. For the integration of configuration management system and personal workspace, a revision of configuration item is connected to the artifact's version of the workspace by the tagging mechanism, and traceability for change history and dependency relations of artifacts can be managed more effectively through integrated change process.

  • Software productivity and quality improvement through software configuration management is based on organized and consistent change management. In change management, artifact identified as configuration item should be able to provide its changed history to the members in group and the members should be able to track down the changes made for the corresponding artifact. General software configuration management systems provide tracking information for artifacts only within the configuration management system, and it does not go further to changes that occur within personal working space. This paper provides a solution that helps tracking down changes that occur not only in configuration management, but also personal artifact's changes through the integration of configuration management system and personal working space. A revised version in configuration management system is connected to the artifact version of the working space by the tagging technique, and traceability can be managed more effectively by sharing the tracking information.

  • To determine the initial configuration of the suspension bridge appropriate idealization model and analysis procedure are proposed as considering the boundary and loading conditions of stiffening girder during the erection. The construction stages of a suspension bridge are divided into two steps which are the first stage of the erection and the second stage of the completion in terms of the erection time of stiffening girders, and depending upon such an erection step the initial configuration analysis is classified the first configuration analysis and the revision analysis of the second configuration. The boundary and loading conditions and the analysis procedures for each stage are suggested and the results are verified by comparing with existing data. The results show that the proposed method provides better solution compared to the results using existing method.
