This paper addresses the issue of workflow on Grid and P2P, and proposes a layered workflow architecture and its related workflow models that are used for not only distributing workflows' information onto Grid or P2P resources but also scheduling the enactment of workflows. Especially, the most critical rationale of this paper is on the fact that the nature of Grid computing environment is fitted very well into building a platform for the maximally parallel and very large scale workflows that are frequently found in very large scale enterprises. The layered architecture proposed in this paper, which we call Enterprise Workflow Grid Architecture, is targeting on maximizing the usability of computing facilities in the enterprise as well as the scalability of its underlined workflow management system in coping with massively parallel and very large scale workflow applications.

The purposes of this study were to a) measure the service quality attributes of foodservice type such as school foodservice, hospital foodservice and business & industry(B&I) foodservice, managed by contract management company(CMC), b) compare with service quality attributes by CMC scale, c) analyze overall customer satisfaction(CS) by the foodservice type and the CMC scale, and d) identify the effect of service quality attributes on an overall CS by the foodservice type and the CMC scale. The questionnaires were handed out to 6,620 customers of 207 school, 38 hospital, and 86 B&I foodservices in 108 CMCs. The statistical data analysis was completed using SPSS Win(ver 12.0) for descriptive analysis, t-test, reliability analysis, and multiple linear regression analysis. From an analysis on service quality attributes, 'proper arrangement of table and chair at hall distribution(3.53)', 'operation of nutrition education(3.50)' were highly perceived to student, 'correctable serving(4.08)', 'serve at fixed distribution time(4.08)', 'kindness of serving employee(4.04)' were highly perceived to patient, 'employee's kindness(3.84)' were highly perceived to customer of B&I. In comparison of service quality attributes by CMC scale, most scores of large enterprise(LE) were significantly higher than small and medium sized enterprise(SME) in school foodservice, hospital foodservice and B&I foodservice. Overall CS levels were 3.53 out of a maximum 5 on B&I, 3.46 on school, and 3.44 on hospital and were evaluated differently CS score by CMC scale. Finally, regression results for the effects of service quality attributes on overall CS by each of foodservice type were identified significantly different service quality attributes by foodservice type such as school, hospital, B&I(p<.001) and by CMC scale. For considering the goal of enterprise on profit-making through CS and the needs of customer on CS at moment of truth(MOT), the findings should be applied to the CMC and the foodservice industry.

분배시스템에서 완제품에 대한 재고통제 운용전략은 기업들에 있어 많은 관심의 대상이 되어 오고 있으며, 스케일메리트(scale merit)기대를 위한 소종대량 취급방식은 고객 요구의 다양화로 더 이상 지속하기 힘들게 되었다. 이러한 환경변화에 대응하기 위하여 많은 기업들은 다양한 제품을 취급하는 추세에 있다. 그러나 기업이 고객 요구다양화에 부응하기에는 많은 비용이 소요된다. 게다가 잔여재고는 진부화 또는 불량재고가 되어 기업에 부담을 가중시킨다. 이러한 비효율적인 문제해결을 위하여 본 연구는 다종소량 취급 방식과 소종소량 취급 방식의 비용비교를 통하여 물류수송비용 및 재고비용 감소의 합리화를 도출 하였다.

Prevention of the disasters is the best welfare to workers and it brings the growth and stability of an enterprise, finally uplifts the national competitiveness. Because small-scale businesses do not have safety and health managers, the government provides a wide range of safety and health management supports to small-scale businesses. However despite of this government's effort, the industrial accident rate of small-scale businesses does not decline, which is mainly because the projects are not differentiated according to the risk level of individual business. Therefore, this paper aims to obtain implications concerning a plan to conduct a reliable assessment of education through a safety job assessment, and to build a framework which may improve a technical area through the AHP analysis.

In this paper, scale efficiencies and relative efficiencies of R&D projects in Industrial Technology Program, sponsored by Ministry of Trade, Industry and Energy, Korea, are calculated and compared. For the process, various DEA (Data Envelopment Analysis) models are adopted as major techniques. For DEA, two stage input oriented models are utilized for calculating the efficiencies. Next, the calculated efficiencies are grouped according to their subprograms (Industrial Material, IT Fusion, Nano Fusion, Energy Resources, and Resources Technology) and recipient types (Public Enterprise, Large Enterprise, Medium Enterprise, Small Enterprise, Lab., Univ., and etc.) respectively. Then various subprograms and recipient types are compared in terms of scale efficiencies (CCR models) and relative efficiencies (BCC models). In addition, the correlation between the 1st stage relative efficiencies and the 2nd stage relative efficiencies is calculated, from which the causal relationship between them can be inferred. Statistical analysis shows that the amount of input, in general, should increase in order to be scale efficient (CCR models) regardless of the subprograms and recipient types, that the 1st and 2nd stage relative efficiencies are different in terms of the programs and recipient types (BCC models), and that there is no significant correlation between the 1st stage relative efficiencies and the 2nd stage relative efficiencies. However, the results should be used only as reference because the goal each and every subprogram has is different and the situation each and every recipient type faces is different. In addition, the causal link between the 1st stage relative efficiencies and the 2nd relative efficiencies is not considered, which, in turn, is the limitation of this paper.

현재의 우리나라 전자 관련 산업 분야 중 대기업과 협력 관계에 있는 협력 업체의 IT 협업 수준이 주로 생산 현장과 관련 있는 ERP나 GROUPWARE을 중심으로 초기 단계의 적용 및 활용 수준에 머무르고 있을 뿐만 아니라 새로운 시스템 도입 및 산업계의 변화를 적시에 반영시키지 못하는 단점이 있었다. 지속적인 전자 분야 산업 발전에 따라 보다 정확한 세부 분야별 생산성 및 매출액 등의 데이터 활용이 경영 활동에 필요하다. 또한 적극적인 GROBAL 경쟁 체제에서의 경쟁 우위 확보를 위하여 현행 시스템의 고도화 뿐만 아니라 생산, 재무 데이타의 의미있는 연계를 통하여 EIS 등의 솔루션을 집중 도입하여, 경영 의사 결정을 효율적이고 신속하게 함으로서 국제적인 경쟁 체계와도 시장 선도형 기업군으로 성장 할 필요성이 대두되고 있다. 본 논문에서는 기존의 국내외 전자 산업대 중소 협력 업체 간의 협업 체계 중심의 현행 시스템을 대상으로 ISP 기법을 적용하여 장단점을 분석한 후, 새로운 공통의 시스템 구축을 위한 상생 혁신 프로그램 도입을 제안한다.

As disasters in the modem era become a large scale and complexity, no single entity can manage them. Instead collective cooperation between civilian, enterprise, school and government sectors is significantly needed, along with a well prepared mechanism. Thus, I attempt to construct the applicable network of civilian, enterprise, school and government sectors for disaster management through exemplary case studies of established countries as well as Korea's current operations and its drawbacks, based upon a networking design of disaster management organizations as belows: Firstly, it is cooperation and coordination among relevant organizations that are required essentially in the new era, in view of formative condition of necessary environment for civil participation. The cooperation and coordination can be made only through the network of civilian, enterprise, school and government sectors. Secondly, in order to build up the network, major roles and tasks which should be done by civilian, enterprise, school and government sectors respectively are listed based upon a stage of disaster management. Thirdly, operation models of a safety monitoring unit, a disaster prevention unit, a emergency response unit, and a rehabilitation unit are proposed in line with the network of civilian, enterprise, school and government sectors in regional base.

Enterprise resource planning(ERP) in nature entails large scale business process redesigns and the corresponding risks. To reduce such risks, enterprise modeling(EM) approach could be adopted through which ERP is planned and effectively implemented on a consistent basis throughout the entire organization. The scope of this paper is to report on EM experiences and lessons learned in the process of ERP implementation. Through a case study, this paper presents and EM methodology which takes due account of strategic business processes, information flows, organizational requirements, and their interdependencies. To assess the impact of distributed application scenarios on effective ERP implementation, alternative EMs have been created and evaluated whether they support information requirements for strategic decisions and day-to-day operational activities, core business processes, and business functions as required. Practical issues and problems raised in the EM process have been discussed.
