  • Finding an optimal solution in MADN[(Multi-Attribute Decision-Making) problems is difficult, when the number of alternatives, or that of attributes is relatively large Most of the existing mathematical approaches arrive at a final solution on the basis of many unrealistic assumptions, without reflecting the decision-maker's preference structure exactly. In this paper we suggest a model that helps us find a group consensus without assessing these parameters in specific cardinal values. Therefore, This research provides a comprehensive Decision Making of the theory and methods applicable to the analysis of decisions that involve risk and multiple criteria attributes. after, The emphasis of the procedure will be on developments from the fields of decisions analysis and utility theory of Taguchi Method. This theoretical development will be illustrated through the discussion of several real-world application and a case study. When the multiple number of decision makers are involved in the decision making procedure, the problem of uncertainties invariably occurs, because of the different views between them. In this paper, New decision making model using Taguchi Method is applied to effectively model the multi-attribute-decision making(MADM) procedure in the uncertainties dominated two area(quantitative and qualitative factors), Quantitative factors evaluation is used Loss Function of Taguchi, qualitative factors evaluation is used 50 ratio by each specialist. thus it can be used for aiding of preferable alternative. as a result, We will be proved efficiency about New decision making model of applied Taguchi Method with Analytical presentation of all the expecting outcomes when a specific strategy or an alternative plan is selected under expecting future environment.

  • The purpose of this study was to explore decision making phenomenon of living kidney donation experienced by kidney donors. Data were collected through semi-structured indepth interviews from 12 kidney donors. All interviewes were audiotaped and transcribed verbatim. Constant comparative analysis was used to analyze the data with NUDIST4.0 software program. process have effects on the execution of kidney donation. Based on the degree of "wish to give", three distinct patterns were identified: Voluntary, compromising, and passive. The voluntary decision making was the most frequent one, while the passive the least. The degree of "wish to give" was influenced by intimacy between the donor and the receipient, geographical locations, economical efficiency of kidney transplantation, and religion. Each pattern was explained by describing interfering and facilitating factors as well as other issues occured in the decision making process. The results of this study will help nurses make effective nursing intervention by understanding the characteristics of decision-making patterns and decision-making process to donate a living kidney.

  • It is critical to select an appropriate technology valuation method when the characteristics of a technology and valuation environment are variable. To ensure high quality decision making when selecting a technology valuation method, it is necessary to understand the principles of a good technology valuation method, and define and apply a decision making theory for selecting an optimal method. The authors propose that Axiomatic Design Principles can be applied as a decision making theory. In order to apply Axiomatic Design for this problem, this paper describes four domains(customer, functional, physical, and process domain) and four axioms(independence, information, cost, time axiom) for the decision making process for the optimal technology valuation method. The result of this study will contribute flexibility to the dynamic technology valuation process.

  • This paper aims to construct an effective decision making model on selection of product design in product development using fuzzy AHP technique. It is expected that this paper contributes to enhancement of company's market competitiveness by shortening the lead time to develop a new product and minimize initial investment. The proposed model using fuzzy AHP enables quick decision making by integrating and analyzing all customer requirements related to a product. In addition, it can deal with vagueness and uncertainty of decision making process using fuzzy set theory. Decision making processes for evaluating the best selection of product design are also constructed to describe the exact concept of development. A tennis racket is shown as an example. The proposed model is expected to be applied in various fields of managerial decision making processes as well as of product development process.

  • We attempt to make regional innovative capability indices for overall understanding of regional innovation. We'll analyze various indicators on it using fuzzy set theory and compare regional innovative capabilities of 16 regions in Korea. The fuzzy set theory can reflect more normally the uncertainty of the stakeholder's responses than other decision making analysis methods. The overall results suggest that experts on regional innovation rank GRDP most important and Daejeon is the most innovative region. Building up regional innovative capabilities should be made for more balanced national land development.

  • The purpose of this study is to consider the criteria for decision-making of industrial location in view of substituting production factors through maximizing profit instead of minimizing transportation cost. This paper makes use of mutual relationship between spatial economy in Euclidean distance and substituting production factors in production theory. Therefore, this paper will develop weak points in classical theory of industrial location by introducing production theory which has conception of substituting production factors.

  • 우리는 여러 종류의 인과적 믿음을 지니고 있으며, 인과적 믿음은 합리적인 결정을 내리는 과정에서 중요한 역할을 한다. 이 직관을 발전시킨 인과적 결정 이론은 행위자의 결정이 합리적이라는 설명을 제시하기 위해서 그 행위자의 결정이 의존하는 인과적 믿음을 명확하게 밝히는 것이 필요하다고 주장한다. 그럴 필요가 없다는 입장의 증거적 결정 이론은 뉴컴 문제를 통해 반박된다. 그러나 뉴컴 문제의 다양한 형태 중에서 의학의 뉴컴 문제가 증거적 결정 이론을 반박하는 데에 가장 성공적이라는 일반적 판단은 잘못이라는 점이 본 논문에서 논증된다. 본 논문은 의학의 뉴컴 문제는 인과 관계를 명료하게 진술함으로써 오히려 증거적 결정 이론을 반박하기 어려워진다는 점을 지적한다. 이 과정에서 본 논문은 증거적 결정 이론과 인과적 결정 이론 사이의 차이점을 드러내고, 합리적 결정 과정에서 인과적 믿음이 정확하게 어떤 역할을 하는지를 밝힌다.

  • 산업이 발전함에 따라 도로 터널의 사이즈와 길이는 계속적으로 증가해 왔으며 그에 따른 터널에서의 리스크 또한 증가되었다. 도로터널에서 환기방식을 결정할 때는 다양하고 많은 고려사항을 염두에 두어야 한다. 현재로서는 이러한 것들을 체계적으로 고려하여 의사결정을 지원할 수 있는 방법론 내지 시스템이 제대로 구축되어 있지 않은 실정이며 대부분 전문가의 경험을 바탕으로 한 주관적 판단에 의존하고 있다. 본 연구에서는 기존의 경제성 내지 주관적 판단에 국한하여 의사결정이 이루어지던 관행에서 벗어나 안전성, 환경친화성 등도 충분히 고려하여 결정을 내릴 수 있도록 터널별 최적의 환기방식을 선정하기 위한 일련의 절차와 기준을 제시하였다. 이 때 다속성 효용이론과, AHP기법을 적절히 활용하여 전문가 및 설계자의 주관적/정성적 평가를 객관적/정량적으로 측정할 수 있도록 하였으며, 환기 방식별 종합적 효용을 산출할 수 있는 함수를 도출하기까지의 방법론을 제시하였다. 본 논문에서 제시하는 방법론을 바탕으로 보다 합리적인 의사결정이 이루어질 것을 기대한다.

  • Wrinkle and fracture are two major defects frequently found in the sheet metal forming process. In this process there are more than one design attributes to optimize and several uncontrollable factors which cannot be ignored in determining the optimal values of design variables. Therefore, attempts to reduce defects through a traditional optimization technique are often led to failures. In this research, a new design method for reducing the wrinkle and fracture under uncontrollable factors is presented by using decision-making theory. To avoid the psychological difficulties in determining the scaling constants of the multi-attribute utility function by using the ordinary lottery questions, a pair-wise comparison procedure is adapted to avoid this problem. The effectiveness of the proposed method is illustrated through a robust design of sheet metal forming process of a side member of an automotive body.

  • As the number of deteriorated infrastructures increases, research on decision-making methods for efficient budget allocation is required. Thus, this study considered the application of utility theory for asset management of deteriorated infrastructure. In decision-making, methods that enable quantitative measurement were proposed, attributing the aging, economic feasibility, and ripple effects. This study is meaningful as a basic study of decision-making methods, and we will conduct research applied to case studies in the future.
