Data mining is widely used for turning huge amounts of data into useful information and knowledge in the information industry in recent years. When analyzing data set with continuous values in order to gain knowledge utilizing data mining, we often underg
이 논문에서는 백본 네트워크의 경제적 확장 방법을 제시한다. 기존 연구에서의 네트워크 확장은 기 설치된 네트워크에 새로운 노드를 추가하는 데 그치고 있다. 이 논문에서는 새로운 노드의 추가 외에 기 설치된 링크의 용량 확장 까지를 고려하는 경제적 확장 설계 방법을 제시한다. 경제적 네트워크 확장은기 설치된 네트워크와 perform-ability를 제약조건으로 하면서 비용을 최소화하는 문제로 표현된다. 효율적인 해외 탐색을 위해 이진과 K진이 혼용된 하이
Purpose of this research wishes to present way to more safe and reliable operation way to shopping mall operation companies as well as consumerism through general utilization present condition of customers and satisfaction investigation that use internet
The outsole mold of the shoes has been manufactured using electro-discharge machining by graphite electrode or using casting etc. The study is concerned with the pattern design for the outsole of shoes by CAD, the modeling and the generation of NC data by
This study was limited Gangwon-do's manufacturing companies that participated in the educational-industrial consortium. These companies' present status and activities under implementation identified and interpreted by this study, therefore, are insufficie
In this paper, we propose a systematic procedure to determine standard time and cycle time in a TFT-LCD factory. The proposed procedure mainly consists of data preprocessing, hypothesis testing and Group technology. Data preprocessing extracts relevant da
Recently, the reliability are applied for many industrial products, and many products are required to guarantee in quality and in performance. The purpose of this paper is to present some of reliability prediction methodologies using failure rate database
This paper is to analyze the travel distance and the transport size of the vehicle when the AGV carries multiple-load in the tandem automated guided vehicle systems. The size of multiple-load represents the number of load that the AGV can carry simultaneo
The purpose of this study is to propose guidelines for introducing the Just-In-Time (JIT) production system to enhance the competitiveness of Korean manufacturing companies. This study employed an extensive survey on the use of the JIT production systems
Recall aims to remove the products hazardous to consumers or users from the commerce. However, a recall with a poor decision making procedure could results in disaster to corporations. Therefore, recall managers should establish a proper recall plan in ad
Recently comparison-shopping agent systems are promising to support purchase of buyers in online-shopping environment. This paper proposes a comparison-shopping agent system considered easy access and buyer's preference. Easy access is achieved by minimiz
This paper deals with a batch processor model in which the batch processing times depend on the jobs assigned to the batch. Each job has a distinct processing time which is determined as not the exact value but the range from the lower limit to the upper,
Considered is the concurrent spare part(CSP) requirements problem of new equipment system. In the considered system, when a part fails, the part cannot be repaired and should be replaced. In addition, cannibalization is allowed. It is assumed that the fai
I investigate whether the efficient ratios used as the proxies of the agency costs maintained by Ang et al.(2000) is significant. Utilizing a sample of 77 manufacturing companies listed on the KOSDAQ from the TS2000 of the KSDA, The results are as follows
This paper studies procedures for bottleneck detection in closed queueing networks(CQN's) with multiple job classes. Bottlenecks refer to servers operating at 100% utilization. For CQN's, this can occur as the population sizes approach infinity. Bottlenec
This paper proposes the heuristic approach for the generalized GT(Group Technology) problem to consider the restrictions which are given the number of cell, maximum number of machines and minimum number of machines. This approach is classified into two st
Slotted ALOHA(S-ALOHA) is widely used in local wireless network. We analyze the performance of contention-based model in wireless LAN using S-ALOHA protocol. We analyze the performance of binary exponential backoff (BEB) algorithm under the slotted ALOHA
There are two approaches for evaluating two or more investment projects. One is a total investment approach and the other is an incremental investment approach. We present that ranking projects by the latter is not sufficient for an investor to accept the
This study presents the new dispatching rules of job shop scheduling with auxiliary resource constraint to improve the schedule performance measures related to completion time and due dates. The proposed dispatching rules consider the information of total
The purpose of this study is to develope the model of economy analysis and evaluation to justify the effect of economic feasibility for constructing ERP system in the company. Since the results for the evaluation of alternatives are influenced by the natu
