  • In the modern design technology, a component should be designed to fit into the overall system performance. A design methodology is developed to expedite the mechan- ical design of complex mechanical systems, The relation between the system design and component design is defined by a top-down approach and the results from the system design are utilized in the component design process. As a design example, an automobile exhaust system is selected for the system design and a bellows is chosen for a component design. Design methodology based on the top-down approach consists of five steps; (1) Analysis of service load, (2) Development of a lumped parameter, (3) Completion of the system design, (4) Selection of the component topology, (5) Completion of the component design, A method using a equivalent matrix is developed in order to determine unknown external forces in linear structural analyses. The bellows is also analyzed by the finite element method using a conical frustum shell element. Various experiments are performed to verify the developed theories. The top-down desi- gn approach is demonstrated by a design case using structural and shape optimization technology. Since the method is relatively simple and easy compared to other methods, it can be applied to the general design where system and component designs are involves simultaneously.

  • This paper proposes eight groups of twenty nine scoring criteria that can help designers and practitioners to compare and select an appropriate methodology for a certain problem in designing product service system (PSS). PSS has been researched for more than a decade and is now becoming more and more popular in academia as well as industry. Despite that fact, the adoption of PSS is still limited for its potential. One of the main reasons is that designing PSS itself is a challenge. Designers and developers face difficulties in choosing appropriate PSS design methodologies for their projects so that they can design effective PSS offerings. By proposing eight groups of twenty nine scoring criteria, this paper enables a "step by step" process to identify the most appropriate design methodology for a company's PSS problem. An example is also introduced to illustrate the use of the proposed scoring criteria and provide a clear picture of how different design methodologies can be utilized at their best in terms of application.

  • Capstone design education is essential in the engineering design process according to the certification standards of ABEEK. Capstone design process should be properly trained in undergraduate courses in order to increase the design ability of systems, components and processes within realistic constraints. In this study, a modified design model as a capstone design education model was proposed to reduce the separation between the design process at industrial sites and the design process at university education. The modified design model based on 6-sigma methodology is composed of 6 design steps such as define, measure, analyse, design, verify, and report. Each step has appropriated design contents and tools, and is configured to generate design results. The proposed design model was directly applied to the capstone design class for automotive engineering in Kunsan National University, and it was confirmed that the proposed DMADVR methodology was a very useful design education model to enhance the design ability, teamwork ability and communication skills required by ABEEK.

  • A design methodology for sustainable on the earth requires a synthetic, and holistic perspective to understand natural processes and urban environments. The apperceptive, holistic landscape design methodology includes one united environment combining analysis, planning and design. In addition, the individual process needs to provide enough spatial information and demands evaluation and understanding on the impact of a design result. The perspective and vision of Ian Mcharg, as asserted in his book, Design with Nature (1969), that the earth is one superorganism is being realized with Geodesign technologies. This paper made the following research efforts which can overcome the limit of the present GIS technologies for the sustainable landscape design: Review of the previous researches, analysis of foreign Geodesign cases and applied theories, suggestion of a Geodesign methodology for landscape design, selection of Geodesign tools and technologies for the implementation of the methodology, and finally the demonstration of effectiveness and potentiality by the application of the methodology.

  • Service-Oriented Architecture (SOA) is a new trend for the design of application architecture to enhance the degree of share and reuse with the concept of service. It comes from the current situation where the business environments are changing rapidly and therefore competitions are getting bitter. To cope with such business challenges, business (and/or applications) architecture needs considerably flexibility and reusability, and that's why SOA is accepted as one of the most effective framework for the business applications in these days. In this paper we propose an analysis and design methodology for the applications of SOA. To implement the proposed methodology, the service ontology needs to be defined first, and the tasks such as service profiling, workflow design and service orchestration need to be followed. To validate the expected effects on flexibility and reusability, the proposed methodology was compared with CBD (Component Based Development).

  • Nowadays an information exchange on XML such as B2B electronic commerce is spreading. Therefore the systematic and stable management mechanism for storing the exchanged information is needed. For this goal there are many research activities for connection between XML application and relational database. But because XML data have hierarchical structures and relational database can store only flat-structured data, we need to make the conversion rule which changes the hierarchical architecture to 2-dimensional information. Accordingly the modeling methodology for storing each structured information in relational database is needed. In this paper, we introduce a XML modeling methodology to design W3C XML schema using UML and we propose a unified design methodology for relational database schema to store XML data efficiently in relational databases. In the second place, in order to verify objectivity of a unified design methodology. By the way of Ronald Bourret, First we introduce the method of the transformation from XML schema to object model and second we translate object model into relational database schema. Therefore we show the mutual consistency between those consequence, and so can verify a unified design methodology.

  • 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.

  • Six Sigma uses DMAIC (Define, Measure, Analyze, Improve, Control) methodology as the process of a solving problem. Enterprises already propelling Six Sigma successfully, such as Motorola, GE and consulting companies, also traditionally propose DMAIC methodology. But, from activating Six Sigma, enterprises and Six Sigma-consulting companies propose Six Sigma methodology matching indirection part of office and R&D part. As an example, DFSS (Design For Six Sigma) is part of R&D application in GE. This study investigates Six Sigma methodology corresponding to the Right Process of the kernel factor. Especially for the optimum design of R&D, the study revises the definition of DFSS and the general organization through Lean DFSS methodology research and analysis.
