Taguchi's parameter design is to determine optimal settings of design parameters of a product or a process such that the characteristics of a product exhibit small variabilities around their target values. His analysis of the problem has focused only on a single characteristic or response, but the quality of most products is seldom defined by a characteristic, and is rather the composite of a great number of characteristics which are often interrelated and nearly always measured in a variety of units. The critical problem in dealing with multiple characteristics is how to compromise the conflicts among the selected levels of the design parameters for each individual characteristic. In this paper, the EXTOPSIS Model using SN ratio which can be optimized by univariate technique is proposed and a parameter design procedure to achieve the optimal compromise among several different response variables is developed. Two existing case studies are solved by the proposed method and the results are compared with ones by the sum of SN ratios, the expected weighted loss, and the desirability function.

Thinking methods have been widely recognized as phenomenon of problem solving in architectural design process and as one of the bases of creativity. In recent years the study of thinking methods have become a major focus of design research. And the purpose of the paper will understand the phenomenon of characteristic and classification of thinking methods in the architectural design process. Extensive protocols are recorded. In particular, the protocols contain sufficient information to make a detailed picture of the architect's problem-solving processes. A protocol study is reported in which the experimental data by architect's is analyzed through the visual protocol analysis method. These findings will help understand the architectural design nature. And they supply a direction for creative education for architects and the base for CAAD system development through understanding for architect's thinking methods.

This paper is a study on inductive superconducting fault current limiter design.. We have created simulation for an imaginery power system with inductive superconducting fault current limiter. Then input variables for characteristic analysis and actual manufacturing, and output variables for design results was assigned. Using the results from these variables, the design criterion was determined which was fed into concept design arising from characteristic analysis to determine the inductance of limiting coil and normal state resistance value of triggering coil. These result was put back into design details to finally give out the design result for inductive superconducting fault current limiter.

The purpose of this study was to suggest a silver blouse design by applying modularization. The precedent study of the researcher was used to analyze the design characteristics that were displayed in domestic and foreign silver blouses. This study was taken as the follow-up research as the module components and range of the silver blouse were set up and it was based on to suggest a silver blouse design with application of modularization. The intention was to base on the module system used in various fields to apply the modularization method on the module design research of silver blouse and as a result, it was derived into 6 types. The traditional design reflected on the characteristic of how the silver generation prioritizes practicality and in order to emphasize this, it will be more effective to apply the fastener and folding method for the development of the design. The contemporary design reflected on the characteristic of how the silver generation prioritizes aesthetics and in order to emphasize this, it will be more effective to apply the module composition method where integration can be made according to the desire of the wearer for the development of the design. The trendy design reflected on how the characteristic of the silver generation wants to look younger and the derived modularization method can be applied freely for expression. Since the range, structure, and formation where modularization can be applied are general, it is implied that there is a need to take sustainable development has to be conducted as the tool that can create different types of design.

The purpose of this research is to investigate the nature of direction of the design corresponding to a human-centered design, digitalism, ecological design, and culture-oriented design which is an issue of design in the 21st century, from the design of the inside of a room. As a method of approach to this objective, first, 1 understand the form of boundary structure appearing in space, through the theoretical investigation of a boundary form. This research is trying to elicit the expression characteristic of kineticism which was introduced to the boundary form as a factor constituting space, by investigating the characteristic of kinaticism which was expressed in plastic arts and other genres. As a process of the proceeding of this investigation, It is explained the background, purpose, and method of this study in Chapter I, and look into the characteristic of the unfolding and expression of kinetic arts as well as the structure of a boundary form of space in Chapter II. In Chapter III, I divide the aspect of modern architectural space into realistic movement, relative movement, and associational movement and examine them. In Chapter IV, I investigate a case of modern space in which the three types of the characteristic of movement mentioned in Chapter Three was expressed, and analyze to what boundary structure the space was introduced. Last of all, in Chapter V, I elicit the characteristic of a boundary form of kineticism which was the result that appeared through the above analysis, and present the nature of future direction of interior.

This paper describes of an overview to the strength rules in the Australian AS4100 Steel Structures Code that was first issued in Limit States Format in 1990. It focuses on pertinent and characteristic issues, such as the means of analysis for second order effects in frames, and highlights how the tiered approach may lead to efficient design using advanced analysis techniques. It also considers design against buckling in some detail, and shows how advanced solutions may be readily incorporated into the design rules. Implicit in the formulations are the necessity for ductility of the steel, and the scope of the code is limited to steels that display this necessary ductility characteristic.

In this study, the optimal design of the multi-cavity mold layout and packing pressure for the automobile TCU connector cover is determined based on the injection molding analysis and the desirability function method for multi-characteristic optimization. The design characteristics to be optimized are the warpage and sink marks of the product, the scrap of the feed system, and the clamping force. The optimal design is determined by performing injection molding analysis and desirability analysis for design alternatives defined by a complete combination of five mold layouts and six-level packing pressure. The optimal design shows that the desirability values for individual characteristics are quite high and balanced, and the resulting values of individual characteristics are satisfactorily low.
