ERP system is very popular tool for pushing management innovation and implementing on integrated information system. The main objective of this research is to analyse the reinforcement of Korean ERP system manufacturing firms.

EDI 시스템 개발을 이용한 농산물 신유통체계 개발에 관한 연구

나중경,노경호 동양대학교 1999 동양대학교 논문집 Vol.5 No.1

Electronic data interchange (EDI) has dramatically changed the manner in which interorganizational transactions are conducted. The electronic exchange of transaction documents has had a significant impact on business practices, particularty in the sales and purchase/ merchandising functions of organizations. EDI brings in many benefits to the organization such as reduced costs, faster turnaround, better customer service, and in some forms strategic advantage over their competitors. This study examines the relationship between various innovation characteristics and various attributes of diffusion of EDI in Agricultural organizations. In this study, we intended to suggest two purposes. One is to give the opportunities for agriculturists to sell the good agricultural products at a high price. The other is to give the opportunities for customers to buy them in a low price and for our country to have competitive advantages in UR and WTO system.

나중경,김정숙,이재직 한국산업경영학회 2010 한국산업경영학회 발표논문집 Vol.2010 No.2

TQM의 구성요소를 여러 선행연구자와 품질상 및 ISO 9000기준을 바탕으로 교원참여, 품질개선, 프로세스관리 및 학생만족으로 설정하고, 이러한 TQM의 구성요소(교원참여, 품질개선, 프로세스관리)가 학생만족에 어떠한 영향을 미치며, 또한 학생만족이 교육성과에 영향을 미치는가를 실증분석을 했다. 측정의 집중타당도를 살펴보기 위해 확인적 요인분석, 측정의 내적일관성을 검증하기 위해 신뢰도 분석, 그리고 판별타당도를 확인하기 위해 상관관계분석을 실시하였으며, 연구모형의 적합도와 연구모형의 검증을 위해 공분산구조분석을 실시하였다. 분석결과 내적일관성, 집중타당도, 그리고 판별타당도는 권장치에 가까운 값으로 나타나 큰 문제는 없는 것으로 판단되었다. 따라서 연구모형에 대한 검증을 위하여 각 구성개념간의 자료를 이용하여 인과분석을 실시한 결과 다음과 같은 가설검증 결과를 얻었다. 첫째, 교원참여, 품질개선, 그리고 프로세스관리라는 TQM의 구성요소는 학생만족에 정(+)의 영향을 미치는 것으로 확인되었으며, 각 요소별로 상대적 영향력의 크기는 품질개선(0.440), 교원참여(0.182), 프로세스관리(0.137)의 순으로 밝혀졌다. 둘째, 학생만족이 교육성과(0.701)에 상당한 영향을 미치는 것으로 확인되었다.

CIM시대에서 JIT시스템의 효과적인 운영

나중경 동양대학교 1997 동양대학교 논문집 Vol.3 No.1

CIM is the integrated system for both automated facilities and computer information processing technology and JIT is the system for an exhaustive waste elimination. This paper proposes the successful implementation of system under CIM. The result of the study shows that JIT firms have not achieved better performance in terms of sales in $/employee, operating profit margin, and return on investment than non-JIT firms: but achieved better performances in terms of finished goods inventory firms, raw materials inventory turnover, and work in process inventory turnover. In addition, this study ascertained that JIT firms have achieved much better performance in terms of quality and flexibility than non-JIT firms. One obvious aspect of successful JIT implementation is the commitment of sufficiently large resources in education and training to overcome the cultural resistance to change. Our study was not able to establish a numerical estimate of how much training is enough. We did find that seventeen of the 29 companies, 59%, listed cultural resistance to change as a problem or lack of training as a problem, or both, The upper end of training provided was 50 hours per worker and 150 per manager. A second obvious conclusion from this survey is that just-in-time implementation requires that the company focus on total quality control and total preventive maintenance in the early stages of the implementation process. Both of these steps are needed in order to consistently perform to schedule. A third recommendation is that communication concerning the JIT implementation must involve as many functional departments as possible, The most frequent interdepartmental problems seem to involve production planning, manufacturing, accounting, marketing, and purchaing. Thus, JlT implementation would appear to require a multi-departmental implementation team such as those recommended for MRP implementations.

중소기업에 MRP 도입 방안에 관하여

나중경 동양대학교 1995 동양대학교 논문집 Vol.1 No.1

Management and personnel problems are by far the most serious problems in terms of cost and sources of MRP system failure.The major costs involved are personnel related - the system design team, user education, and maintenance of the data base. The system's success is largely determined by the degree of commitment of management and system users.Sucess is enhanced by the selection of key personnel.those chosen should be educated in MRP concepts and trained in the use of the specific MRP system to be used.This approach ensures that key personnel become qualified users and can properly apply the new technology.Participants must be educated to understand the purposes of the system in order to close the communications gap between manufacturing management and data processing personnel.Technology is moving so rapidly in the manufacturing field that constant education and refresher courses are required. Most MRP implementation failures can be attributed to a failure on the part of management to recognize the commitment in terms of education and data preparation necessary to make MRP work.The benefits of an MRP system can be great, but none will be realized unless the system is accepted by operating personnel, and the decisions of the system are implemented.Experience from all large system implementations has shown that a thorough commitment to these two key elements is absolute minimum requirement for success.This statement is not made to discourage the purchase of an MRP package.On the contrary, author agrees that MRP is one of the most powerful production planning tools available today.My message is simply that if you decide to implement such a package, do it properly and be prepared to pay the cost of good education and good data.A proper implementation will pay a high return; a poor implementation is a waste of money and effort.

DEA를 이용한 지역농협의 경영효율성 개선에 관한 연구 : 경상북도 준농촌형 지역농협을 중심으로

나중경 한국산업경영학회 2014 경영연구 Vol.29 No.3

지역농협은 경제사업과 신용사업의 두 가지 사업으로 운영되고 있다. 신용사업은 수익을 내고 있으나 경제사업은 거의 대부분의 지역농협이 적자를 나타내고 있는 것이 현재의 실정이다. 그런데 2013년부터 신용사업의 환경이 어려워지고 있다. 이를 극복하기 위한 방안은 지역농협의 경영효율성을 제고하는 방법이 될 수 있다. 본 연구는 경상북도 준농촌형 지역농협 35개를 2012년도 경영실적 자료를 대상으로 효율성을 분석하여 그 개선방안을 제시하고자 한다. 선행연구를 통해 도출한 투입변수는 조합원수, 종업원수, 판매비와 관리비, 자기자본으로 선정했고, 산출변수는 경제사업, 당기순이익, 대출평잔, 예수금 평잔으로 선정하였다. 효율성을 분석하기 위하여 DEA 모형을 사용하였으며, 효율성 분석에서 규모의 효율성을 살펴보고 비효율성의 원인이 규모에 의한 것인지 순수기술에 의한 것인지를 살펴보기 위해 규모수익불변(CRS)을 가정한 CCR과 규모수익변동(VRS)을 가정한 BCC 효율성을 산출 기준으로 분석했다. 규모의 경제 측면에서 현재의 규모유지(CRS)가 필요한 지역농협은 11개이고, 규모를 축소(DRS)해야 하는 지역농협은 16개이며, 규모를 확대(IRS)시킬 필요가 있는 지역농협은 7개다. 규모의 경제를 달성하지 못한 16개 지역농협은 타 지역농협 벤치마킹을 통해 규모를 조절하여 비효율성을 개선할 필요가 있는 것으로 나타났다. 또한 효율성이 "1"인 DMU들도 순위를 나타낼 수 있는 잔여기준초효율성 분석방법을 이용하여 35개 DMU에 대한 효율성을 나타냈으며, 각 DMU들의 투입과 산출변수들에 대한 개선안을 제시했다. Local Agricultural Cooperative Federation(LACF) has been operating economic business and credit business. The credit business is currently profitable business, but the vast majority of economic losses show in the economic business. It, however, was difficult in the credit business environment from 2013. To overcome it, they are considered to improve the operational efficiency of the Local Agricultural Cooperative Federation. In this study, it suggests a plan through business performance analysis from 35 Gyeongsangbuk-do Agricultural Cooperative Federations business data in 2012. Furthermore, we consider two factors to analysis; Input and output. Input data consist of union members, employees, sales expenses, administrative expenses, and net worth. Output data select economic business, net income, loan average balance, average balance of deposits. To analyze the efficiency of business, we use the DEA(Data envelopment model) model; CCR model with constant return scale and BCC model with variable return scale utilized to find scale efficiency and pure technical efficiency. In the economy of scale, this paper proposes that 11 LACFs in constant return to scale(CRS), 16 LACFs in decreasing return to scale(DRS) and 7 LACFs in increasing return to scale(IRS). We suggest efficiency rank for efficiency of "1" by using super slack-based measure model, and might improve efficiency to 16 LACFs in decreasing return to scale(DRS) through benchmark the efficiency of "1." In super efficiency analysis, we show the efficiency of 35 DMUs and improvement of input and output variables.
