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.

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.

Silicon semiconductor technology agree that the number of transistors on a chip will keep growing exponentially, and it is pushing technology toward the System-On-Chip. In SoC Design, Specification at system level is key of success. Executable Specification reduce verification time. This Paper describe the design of IMDCT for MPEG Audio Decoder employing system-level design methodology and Executable Specification Methodology in the VHDL simulator with FLI environment.

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.

지구의 지속가능한 개발에 대한 설계 방법은 자연의 과정과 도시환경을 종합적으로 이해하는 통각적(apperceptive), 전체론적(holistic) 관점을 요구하고 있다. 통각적, 전체론적 조경 설계방법은 분석-계획-설계의 개별 과정이 하나의 환경에서 수반되어져야 하며, 각각의 과정별로 공간에 대한 많은 정보를 제공하여야 하고, 디자인의 결과와 영향에 대한 평가와 이해가 수반되어야 한다. 1969년 "Design with Nature"에서 Ian Mcharg가 제시하였던 지구 전체를 하나의 생태계(Superorganism)로 보는 비젼이 Geodesign의 기술 환경으로 현실화 되어가고 있다. 본 논문에서는 기존 GIS의 지속가능한 설계의 지원한계를 극복하고 수행할 수 있는 Geodesign 조경설계 방법에 대해 고찰하고 선행연구의 분석을 진행하였다. 이와 함께 국외의 Geodesign 사례와 적용 이론들에 대한 고찰을 통해 조경설계를 위한 Geodesign 방법론을 제시하였다. 또한 제시된 방법론을 구현하기 위한 Geodesign 기술과 도구들을 살펴보고, 방법론의 적용을 통해 기술적 가능성, 활용 방안 등을 검토하고, 미래의 조경설계에 있어서 본 방법론이 가지는 잠재력과 효율성을 입증하였다.

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).

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.

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.
