Binary Decision방법은 출력을 얻는데 요구되는 결정스텝이 최대 입력변수의 수를 넘지 않도록 한다. BD-PC모듈은 스캔 스피드를 개선하기 위해 이 방법을 이용하여 설계제작되었다. Binary Decision방식에 수반되는 메모리문제를 개선하기 위해 컴파일러 시스템을 개발하였다. 또한, 컴파일된 BD-PC목적프로그램을 BD머신의 메모리에 로디하기 위해 MDS와 BD-PC모듈간에 통신채널을 구성하였다.

In this research, we proposed "coefficient of inequality" as a measure of distributional inequality for an alternative, which is defined as the area between the diagonal line from 0 to 1 and the Lorenz curve of the given alternative. Next, we showed theoretical relationship between stochastic dominance and the coefficient of inequality as a means to determine the preferred alternative when decision is made with incomplete information about decision maker's utility function. Then, two experiments were performed to test subject‘s attitude toward risk. The results of the experiments support the idea that when a decision maker is risk averse or risk prone, he/she can use the coefficient of inequality as a decision rule to choose the preferred alternative instead of using stochastic dominance. Thus, according to decision maker’s attitude toward risk, the decision rule proposed here can be used as a valuable aid in decision making under uncertainty with incomplete information.

도심지 건설 프로젝트에서 적정한 기초공법을 선정하는 것은 매우 중요한 의사결정 중 하나이다. 그러나 아직도 적지 않은 프로젝트에서 단순히 과거의 경험이나 숙련된 기술자의 의견에 기초하여 기초공법을 선정하고 있다. 본 연구에서는 기초공법결정과정을 보다 선진화하기 위해 계층분석법(Analytic Hierarchy Process; AHP)과 선호도함수(Preference Function; PF)를 이용하여 적정 기초공법을 선정하는 의사결정지원시스템을 제안한다. 제안된 시스템에서 계층분석법은 평가기준 간의 상대적 중요도를 반영하기 위해, 또한 선호도함수는 의사결정자의 기초공법 적합도에 대한 선호도를 고려하기 위해 이용된다. 제안된 의사결정지원시스템을 기 수행된 프로젝트 사례에 적용해본 결과, 시스템이 도출한 기초공법과 전문가들이 현장에 대한 면밀한 검토 후 선정한 기초공법이 동일함을 알 수 있었다. 제안된 의사결정지원시스템은 건설현장에서 최적의 기초공법을 선정하기 위한 의사결정 시 매우 유용한 도구로 활용될 수 있을 것으로 기대된다.

A new design scheme of a binary decision tree is proposed. In this scheme a binary decision tree is constructed by using genetic algorithm and FCM algorithm. At each node optimal or near-optimal feature subset is selected which optimizes fitness function in genetic algorithm. The fitness function is inversely proportional to classification error, balance between cluster, number of feature used. The binary strings in genetic algorithm determine the feature subset and classification results - error, balance - form fuzzy partition matrix affect reproduction of next genratin. The proposed design scheme is applied to the tire tread patterns and handwriteen alphabetic characters. Experimental results show the usefulness of the proposed scheme.

It is well-known that the decision rule in the mini-mum mean-squares-error decision feedback equalizer(MMSE-DFE) is biased, and therefore suboptimum with respect to error probability. We present a new family of algorithms that solve the bias problem in the adaptive DFE. A novel constraint, called the constant-norm con-straint, is introduced unifying the quadratic constraint and the monic one. A new cost function based on the constant-norm constraint and Lagrange multiplier is defined. Minimizing the cost function gives birth to a new family of unbiased adaptive DFE. The simula-tion results demonstrate that the proposed method in-deed produce unbiased solution in the presence of noise while keeping very simple both in computation and im-plementation.

The current study examined 3- and 4-year-olds' affective decision-making in a variety of cultural contexts by comparing European Canadian children to Chinese Canadian, Hong Kong Chinese, and mainland Chinese children (N = 245). All children were tested with a delay of gratification task in which children chose between an immediate reward of lower value and a delayed reward of higher value. Results showed that Chinese Canadian and Hong Kong Chinese children chose more delayed rewards than European Canadian children, with mainland Chinese children showing a trend toward more delayed rewards. Across cultures, 4-year-olds chose more delayed rewards than 3-year-olds; and among 4-year-olds, girls made more such choices than boys. The findings are consistent with previous findings that exposure to Chinese culture is associated with better cool executive function, but they also highlight the importance of examining development across diverse cultural contexts.

The power expansion planning is large and capital intensive capacity planning. In the past, the expansion planning was established with the proper supply reliability in order to minimize social cost. However, the planning can't use cost minimizing objective function in the power markets with many market participants. This paper proposed the power expansion planning model using multi-criteria decision rule. This model used multi objective function considering not only cost minimizing but also GENCO's intension. This paper compared proposed model with WASP model in order to verify the result of proposed model.

본 논문에서는 최근의 디지탈논리시스템의 함수구성시에 도입되고 있는 그래프이론에 바탕을 둔 결정도로부터 새로운 형태의 데이터구조 형태인 에지값 결정도를 추출하는 알고리즘의 한가지 방법을 제안하였다. 그리고 이를 기초로 임의의 m치 n변수의 축약된 함수구성을 도출하는 방법에 대해 논의하였다. 제안한 다치논리함수구성방법은 도식적이며 규칙적이고 정규성을 내포하고 있다.

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.

The personality types developed by Gustav Jung are frequently used to identify peopl's decision-making style, especially to determine which functions are dominant ones in the perception and the processing of information. In this paper, the Jungian typology is utilized to investigate if there are any systematic relations between an individual's personality type and her/his attitude toward risk. For this purpose, an experiment was conducted where 99 subjects, mostly students, participated in a computer-simulated horse racing game. Each subject's risk-seeking propensity was measured by the winning chance of the selected horse and the amount of stakes. The results of the experiment show that a decision-maker who is extrovert (E) is attitude and intutive(N) in perception of information is more likely to be risk prone than the introvert(I) and sensing(S) type. Feeling(F) function in information processing seems to induce more risk seeking attitude than thinking (T) function, but the statistical significance could not be found from the data, for this statement.
