  • Occupant protection in the side impact of a car became one of the most important issues of car crashworthiness due to high injury level in a side impact crash. An accurate simulation of the side impact crash is an essential tool for the reduction of development time and cost for side impact safety system. This paper describes a new test methodology that can accurately generate the crash pulses of a vehicle and a door in a very cost-effective manner, and then evaluates the injury values of the dummy for the various sled pulses. This test methodology is simple and easy to approach because the door velocity is controlled by the hydraulic actuator and brake and the seat velocity is only adjusted by the friction force of the hydraulic brake. The superiority of the proposed test methodology is proven by the evaluation of dummy's injury values according to the change of the pressure of the hydraulic brake and by the application as a tool for the development of side airbag.

  • Software development methods have continued to evolve in response to changes in the environment. Structural methodology, information engineering methodology, and object-oriented methodology are the major trends of this change. Each methodology has its own characteristics and advantages, and its applied fields are different. Engineers performing practical work are familiar with applying each methodology, but are not familiar with applying structural methodologies or information engineering methodologies in an integrated manner. Therefore, the maximum effect of the methodology cannot be obtained. With this in mind, we would like to organize and present examples of how to integrate and apply structural methodology and information engineering methodology to the target of each methodology.

  • Component-Based Development(CBD) for a system has benefits in terms of improvement of operation and maintenance as well as reduction of development period. But applying the CBD methodology to a system can give rise to difficulties, which are there should be specialists in CBD and domain to apply and there would be a lot of products resulting in the application. To solve the problems, we suggested a suitable methodology in overall process from analysis to implementation after investigating the methodology applicable to small and medium software system by software systems engineering approach. In the application of the suggested methodology to design a ship design process management system, we could confirm the efficiencies of the methodologies.

  • Mobile-based software development methodology has been vigorously researched from using object-oriented development methodology and component-based development methodology previous structural developing methodology. There are two types of OS in mobile platform which are android and iOS. There is a problem that the application to be developed is developed depending on the device type. To resolve this problem, first, the system structure and design method should be managed effectively. Second, a basic design guide that can be commonly adapted to the each project is required. In this paper, we define a mobile cross platform meta model based on MDA-development methodology, focusing on reusability, portability and interoperability about non - dependent part of the mobile platform. If the proposed meta-model is applied to manage the related information and all the types of Mobile-Apps become available through independent mobile app development process, henceforward, it will be much of help establishing formulaic mobile-app developmental methodology.

  • In this paper, we have proposed Architecture Development methodology which can connect both operational view and system view. The Functional Architecture can connect both user and developer, and it is located between Activity analysis and System analysis. We suggest the new architecture methodology using the Functional Architecture and it provides effect to analyze the connection between user(military) and developer(enterprise) in Defence R&D and the new Architecture with the feedback analyze activity on a point of system view and the new architecture make the functional architecture.

  • This paper is about our experience of developing a context-aware exhibit guide system called MyGuide by applying Simtext development methodology. In particular, we introduce some issues to be considered in development process, the way that we solved them, and other things related to context. In requirements elicitation phase, we reduced the complexity of requirements by separating business logic requirements and context-awareness related requirements. After that, we modeled context, and designed software architecture, classes, and database in sequence during design phase. We considered system requirements and context modeling issues for context modeling because it influences class and database design.

  • For the implementation of science and technology based agriculture, one of the domestic rural development strategies, it is essential that we should have an integrated information system for each crop production. This system would be a web-based collaborative system for the local farmer and the advisors who guide the crop production technically, and would be capable of providing the real-time analysis functionalities and expert knowledge. In this thesis, we proposed a component based development methodology called MCPI(Method for Crop Production Information system) which employs and re-organizes Marmi-III, the popular existing component based methodology for the large scale S/W development project. In particular, MCPI is designed to reflect the characteristics of crop production information system and for the small and medium S/W project. To show the applicability in real-world problems, we develop and evaluate a prototype which is based on our proposed methodology for the rice production farmer in mid-Choongnam area.

  • As the automated vehicle system evolves, electronic devices and control software installed in vehicles are increasing. Therefore, automated vehicle electrical and electronic system (E/E system) design for ensure system integration, software modularization, system reusability, and scalability at the design stage of the automated vehicle is actively studied. This paper introduces a design methodology for automated vehicle E/E systems that employs by using cyber-physical systems (CPS). An automated forklift system was designed to examine the effectiveness of the proposed methodology. This paper showed that the proposed CPS design methodology enables an effective development of automated E/E control systems. Compare to existing design methodologies, it provides higher reusability of individual modules and an easier way to integrate control system elements such as controllers, sensors, and actuators.

  • This paper proposes a systematic design methodology for the Takagi-Sugeno(TS) model based fuzzy control system with guaranteed stability and additional constraints on the closed-loop pole location. These combined two objectives are formulated as a system of LMIs(Linear Matrix Inequalities). Since LMIs intrinsically reflect constraints, they tend to offer more flexibility for combining various constraints on the closed-loop system. To demonstrate the usefulness of the proposed design methodology it is applied to the requlation problem of a nonlinear magnetic bearing system. Simulation results show that the proposed LMI-based design methodology yields not only maximized stability boundary but also the desired transient responses.
