A vendor selection problem consists of two different kinds of decision making. First one is to choose the best suppliers among all possible suppliers and the next is to allocate the optimal quantities of orders among the selected vendors. ln this study, a
Complex products may present more than one type of defects and these defects are not always of equal severity‘ These defects are class ified according to their seriousness and effect on product quality and performance. So, demerit systems are very effecti
The purpose of this study was to investigated correlation between personal aggression and skin conductance level during watching attack image. Twenty three male (2 1. 4土1. 8 years) college students participated in this experiment. A personal aggression of
ln this paper, we proposed the modified method of Metcalfe ’s law that is “ Modfied law" in evalllating the network power for the measurement of combat effectiveness in C41 system. It is applied to JFOS-K (Joint Fire Operating SystemKorea) C41 system that
To survive head-to-head competition, we should keep our labor productivities above those of other nations. However, our labor productivities are low compared to those of the developed countries. It is the well-known fact that we make up for the productivi
Bonding glasses is one of the important PDP (Plasma Panel Display) manufacturing processes. Bonding process includes aligning front and rear glasses with fixing clips. In this process, clips have to maintain perfect alignment between the front and rear gl
Reliability has been considered as a one of the major design measures in various industrial and military systems. The main objective is to suggest a mathematical programming model and a hybrid parallel genetic algorithm(HPGA) for the problem that determin
The purpose of this study was to compare the difference of driving pattern between male and female drivers for a straight driving and unexpected situation using driving simulator and motion data. The participants included total 60 university students; 30
The existing reliability evaluation models which have already developed by the corporations are so various because of using Maximum Likelihood Method. The existing models are very complicated owing to using system designing methods Therefore, it is very d
Recently, paradox management is a new paradigm to solve the management dilemmas. This is a new perspective and a creative way of thinking to draw the synergic effect by pursuing simultaneously the conflicting elements. As one method for the paradox manage
This paper presents an app lication of heuristic approach to problem of designing reliable network expansion. The problem essentially consists in finding the network topology that satisfies given set of reliability constraints. To efficiently solve the pr
This study explores the application of the analytic network process (ANP) approach for the evaluation of R&D projects with heterogeneous objectives. The ANP model in this study produced the final priorities of projects with respect to several performance
Us ing the known result of the expected bllsy period for the triadic Min (N, T, 0) operating po licy applied to a controllable M/GI1 queueing model, its upper and lower bounds are derived to approximate its corresponding ac tual value. 80th bounds are rep
The purpose of this study was to detect early children with hyperactivity which is one of the symptoms of Attention Deficit-Hyperactivity Disorder (ADHD). This study used two methods: K-CBCL and observation of children’s behavior. K-CBCL was done online b
시계열데이터는 ARMA 분석에 적합지 않은 요소를 내재하고 있는 경우가 있다. 특히 선형성과 주기성을 가진 요소가 확률적인 분포와 자주 혼재 되어 있다. 이 논문에서는 이런 선형적 주기적 요소를 찾아내고 분석하는 방법을 제시한다. 특히 주기적 요소는 여러 주기가 층층이 겹쳐져서 나타난다, 주기 간에 는 서로 일정 정수비율을 유지하며 , 한 주기 안에 다른 주기가 내 포되어 있는 경우(nested periods)가 많다. 시간규모(time-scale) 개
Recently, the illlportance of quality con trol on the online co llabora tion system is increasing, since it is realized that many parti cipants do not guarantee the quality of online collaboration’ s Oll tpu t anylllore. Hence in this paper, we propose th
PC camera-based instant messenger have problems of video image break/delay and noise. The reason is caused by a composed problem that PC Camera is belong to the connected PC and operating in the Pc. This research suggests an instant messenger that llses n
The defense M&S (Modeling and Simulation) techniques are being used by the ROK Army for developing the efficiency and economics of national defense at operational level. But the problem we have found is the lack of interoperability and reusability in defe
Nowadays, customers have increasing needs, so more and more enterprises are selling their products with additional services and or contents. The emergence of service added to the product leads to the emergence of the Product-Service Systems(PSS). Many res
The conning display which is located in the ship bridge shows the variolls important information such as ship position, ship speed, track data, rate of turn, thruster rpm so on, and is one of the IBSs(lntegrated Bridge Systems). 1n this study, the survey
