This paper proposes a real-time resource allocation algorithm for minimizing the completion time of overall workflow process. The jobs in a workflow process are interrelated through the precedence graph including Sequence, AND, OR and Loop control struc
This paper considers a six sigma project for improving productivity of the brace complement center pillar. The project follows a disciplined process of five phases: define, measure, analyze, improve, and control. A process map is used to identify proces
In mobile ad-hoc networks(MANETs), nodes are mobile and network topology changes very frequently. The mobility of nodes does affect the system performance. There has been considerable attention on the mobility models, however, most work is confined to t
The potential needs as well as visible needs of customer should be considered in order to research and analyze of the customer data. The methods to analyze customer data is classified into customer segmentation, clustering analysis model, forecasting cu
Many producers put sampling inspection policy into the way of their convenience. Examples of the convenience are irregular lot size and too small sample size. Because they don"t use a standard sampling inspection policy, they can not guarantee the quali
본 논문에서는 재시도와 완전입력 규칙을 갖는 BMAP/PH/0 대기시스템에 대한 주요 성능평가척도와 시스템의 정상상태 조건을 제시한다. 고려되는 시스템은 모든 서버가 서비스를 하고 있을 경우 도착이 이루어지는 배치도착은 모두 손실되며, 반대의 경우 도착하는 배치는 서비스를 받기 위해 시스템에 들어가게 된다. 만약 쉬고 있는 서버의 수가 불충분하여 배치의 일부가 즉각 서비스를 받을 수 없다면, 일단 오빗으로 이동하고 표준 재시도 대기시스템의 규칙에 따
This study is provide information in the development of energy conservation technologies by means of technological demand survey covering energy market and industrial field among energy-related technologies. For this purpose, we check both the present
This paper is concerned with a six sigma application to non-manufacturing process. Based on the comparison to manufacturing process, non-manufacturing process has some specific characteristics. The main focus of this study is to introduce an empirical c
In this paper, we consider a planning problem arising from printed circuit board manufacturing industries. Given a set of several types of PCBs, component feeders and surface mounting machines in series in a PCB assembly line, the problem is to define t
Event trees are widely used graphical tool to denote the accident inintiation and escalation to more severe accident. But they have some drawbacks in that they do not have effjcient way of updating model parameters and also they can not contain the info
다양한 데이터 마이닝 기법들의 발전과 더불어, 속성 (Feature 또는 Attribute)의 범위 (Dimension)를 줄이기 위해 많은 요소 선택 방법이 개발되었다. 이는 확장성 (Scalability)을 향상시킬 수 있고 학습 모델 (Learning Model)을 더욱 쉽게 해석할 수 있도록 한다. 이 논문에서는 네스티드 분할 (Nested Partition, 이하 NP)을 이용한 새로운 최적화 기반 속성 선택 방법을 NP 기본 구조와 다양한
In order to implement Artificial Intelligence, various technologies have been widely used. Artificial Intelligence are applied for many industrial products and machine tools are the center of manufacturing devices in intelligent manufacturing devices. T
The risk management is an organized method for identifying and measuring risk and for selecting, developing, and implementing options for the handling of risk. The risk management covers all programatic and technical factors which affect the system deve
The issue of using information system to ensure competitive power in the market is rising. The outsourcing methods that entrust activities of information system of companies to other expert agencies are increasing as the enterprises make a lot of effort
Exact solutions for practical-size problems in job shop will be highly inefficient. Scheduling heuristics, therefore, are typically found in the literature. If we consider real-life situations such as machine breakdowns, the existing scheduling methods
In this paper, we proposed the SCM logistics roadmap in other that the "Northeast Asian Distribution Hub" policy of the government can be realized more effectively. First, we analysed the requirements of SCM roadmap by examining the situation of Northea
QFD(Quality Function Deployment) is a system for translating specific customer needs into detailed product requirements which are deployed throughout design, production, marketing and support operations. QFD is a team tool. However, most of commercial Q
The package loading process of the lumbering industry is an operation that after a pair of workers binds three or six lumber into a unit and cut the both ends of the lumber, carry and pack and load the weight cargo of 30-50㎏. The package loading process
Box-Cox model and T-factor method have been widely used to measure economic depreciations for industrial property. The Box-Cox model which combines economic efficiency with depreciation pattern is here extended to the reliability function. To do so a Ra
The high degree of viscosity and the non-Newtonian fluid dynamics characterizes the process inside a glass furnace. Because the temperature is fluctuating in very short time-intervals, it is hard to determine that the status of its fluctuation is stable
