ERP시스템의 성공적인 도입 전략

강문식 啓明大學校 産業經營硏究所 1999 經營經濟 Vol.32 No.2

요 약최근에 ERP 패키지의 도입을 통한 기업의 업무 프로세스를 재설계 함으로써 기업의 경쟁력 을 강화하려는 노력이 한창이다. 그러나, 많은 ERP 패키지 도입 시도에도 불구하고 성공사 례가 많지 않은 것도 사실로 드러나고 있다. 이러한 실패 사례는 ERP 패키지에 대한 올바 른 이해 부족으로 인해서 생기는 경우가 많은 것으로 나타나고 있다. 본 연구에서는 ERP 패키지 구축에 영향을 주는 요인들 즉 구축 방법론, 정보시스템, 조직구조, 업무프로세스 및 갈등집단의 관점에서 실패원인을 분석하고 나아가 이를 종합하여 성공적인 구축전략을 제시 한다. ERP도입의 실패 원인은 한 두 가지의 요인에 국한되는 것이 아니고 여러 가지가 복 합적으로 나타난 결과인 것이다. 본 연구에서 제시하는 방법과 전략으로 각 기업에서 ERP 시스템 도입에 대한 분석을 시도함으로써 ERP 시스템의 성공적인 도입에 대한 확신을 얻을 수 있을 것으로 기대한다.ABSTRACTCurrent business environment has been changed so rapidly and companies need to overcome those changes to survive. Many companies have tired to restructure their business operation by employing techniques such as down sizing, BPR, or restructuring. The information systems are the most important parts of the restructuring efforts. Recently, many companies have employed ERP (Enterprise Resources Planning) to solve the problem. However, it is true that not many companies succeed to employ the ERP systems. The failures are often caused by the lack of understanding ERP systems.This paper analyzes the causes of the failures in terms of implementing methods, information systems, organization structures, business processes, and conflicting groups. With the result of the analysis, this study presents the strategies for successful implementation of ERP systems. The failures of employing ERP systems are not caused by one or two factors. They are the result of combined factors. We expect that the strategies we present in this paper with other analysis can assure the successful implementation of ERP systems.

하이브리드형 신경망을 이용한 데이터 마이닝의 최적화 기법

강문식,이상용 공주대학교 과학교육연구소 2002 과학교육연구 Vol.33 No.-

최근 데이터 베이스에서 가치있는 정보를 찾아내기 위한 데이터 마이닝 연구가 활발하게 진행되고 있으며, 그 기법으로는 신경망 모델을 사용하는 방법이 많은 연구성과를 거두고 있다. 현재 사용되고 있는 신경망 모델의 문제점은 감독 학습 방법의 경우 목적 패턴의 오류로 유도될 수 있는 오버피팅 문제가 발생하고, 무감독 학습 방법의 경우는 데이터의 정규화 과정으로 인하여 중요한 정보가 왜곡될 수 있어서 만족할 만한 군집화나 분류 효과를 거두지 못하고 있다. 본 논문에서는 이런 문제점들을 해결하기 위해, 하이브리드형 신경망을 제안한다. 실험결과 본 신경망은 어떠한 입력 패턴에 대해 목적 패턴을 만들 수 없거나, 존재하지 않는 경우에 효과적으로 사용될 수 있음을 알 수 있었다. Recently, people have been studying on data mining to find out more valuable information in data bases. There have many good results of studying on the ways to use Neural Network Model. Now, some problems like overfitting are on the rise. Overfitting means that supervised learning methods lead to the error of target patterns. Besides, unsupervised learning methods cause the problem to distort some important information through the process of regularizing data. So we can't expect the satisfying results of clustering and classification. To solve the problems, the paper suggests a hybrid neural networks. According to experiments, the neural networks can be effectively put into use in cases of not being able to make target patterns with some input patterns or non-existing patterns.

The basic Physical properties, Slump, Slump flow, Air content, Bleeding, and Settlement of concrete was investigated to test Characteristic of Setting and to evaluate the relation between Model specimen and Heat of hydration for construction Over the High Temperature(CFT). The objective of this study is to take the partial core after the cementation of Model specimen, test the compression intensity and analyze the relation to Test piece.

One of the most important reasons that CFT is used in many conditions is by using that we can achieve the effect, which reduce the section of the member. This research purpose to find the most ideal composition, which is achieved by the investigation in the concrete's property of matter like ability of Slump, Slump Flow, Air content, Bleeding, and Settlement when the high strength of concrete which is over 80MPa is used m the CFT column.

STAGE EFFICIENCY ESTIMATION BY MODIFIED MIMT USING NLP

Kang, Mun Sik,Kim, In Won,Park, Sun Won 한국화학공학회 1996 Korean Journal of Chemical Engineering Vol.13 No.2

Unmeasured process variables or parameters caused by cost consideration or technical infeasibility can be mostly estimated using data reconciliation techniques. Since, however, the gross errors possibly present in the process measurements deteriorate the data reconciliation results, the reconciled estimates may be biased solutions that are different from the true values. In this paper, the enhanced data reconciliation and gross error detection method, modified MIMT using NLP, was applied to a flash distillation system. It calculated the reconciled values of the measurements as well as the optimal estimates of stage efficiencies which were not measured. These techniques using NLP showed the robustness when compared to the conventional algorithms using linearization techniques.

SPE-composites which was prepared with impregnation-reduction method for hydroen production were investigated with morphological and electrochemical analysis. As Pt reagent`s concentration increased, Pt loadings increased. However, reductant`s concentration had a little effect on Pt loadings. By the morphological analysis, it was found that Pt was deposited inside of SPE. Furthermore, with electrochemical analysis, we found that Pt loading, electricity, roughness factor and active surface area were 2.05 mg/cm², 14.20 mC, 21.55, 10.51 cm²/mg respectively at reducing agent concentration 0.05 ?/L. Therefore, we found the deposited Pt inside of SPE would give an effect on electrical characteristics of SPE-composites.

시클로프로판 고리가 없는 피레트린계 농약 Oxime O-Ether의 합성과 Fenvalerate의 합성 연구

강석구,문홍식 성균관대학교 기초과학연구소 1985 論文集 Vol.36 No.1

An Oxime O-ether(Shell's pyrethroid), a pyrethroid insecticide not containing a cyclopropane ring, was synthesized from chlorobenzene and isobutyryl chloride. Friedel-Crafts acylation of chlorobenzene and isobutyryl chloride in the presence of AlCl_3 gave 1-(4-chlorophenyl)-2-methyl-1-propanone. Oximation of the above ketone with NH_2OH·HCl, followed by O-alkylation of the oxime with m-phenoxybenzyl bromide afforded an oxime O-ether. NaBH_4 reduction of 1-(4-chlorophenyl)-2-methyl-1-propanone, followed by bromination with PBr_3 yielded 1-(4-chlorophenyl)-2-methyl-1-propyl bromide, which would be a good intermediate for the synthesis of fenvalerate, a pyrethroid insecticide not containing a cyclopropane ring.

Of the case of malignant astrocytoma, spontaneous transdural extension is very rare. Only several cases of transdural extension of primary intracranial tumor are reported. However, these cases are through the foramina of the skull base. We have experienced a case of malignant astrocytoma which directly extended out through the dura and calvarium near the pterion of the left side.
