A design code validated against the thermal analysis results of CFD and published RTE code for a regeneratively cooled combustion chamber has been developed. The major function of the code is to predict the regenerative cooling performance and stress of the chamber wall. Adopted are the empirical correlation for the evaluation of the heat transfer coefficient of hot gas and coolant, and theoretical formula for the fin effect of the channel rib. The hot-gas-side wall temperature from the present code shows 100 K difference at most compared to RTE results. It shows less than 10 % difference for the heat flux thrall through the chamber wall and hot-gas-side convective heat transfer coefficient. The major cause of the wall temperature difference is due to the underestimation of the fin effect of the channel rib.

Many companies make considerable efforts in implementing supply chain management systems to increase their competitiveness. In particular, there are significant investments in their ICT (Information and Communication Technology) and supply chain. However, considerable diversity exists in how well firms have been able to assimilate ICT and leverage the business value of it. In addition, studies on supply chains, particularly Real Time Enterprise (RTE) competence, which is cited for rapid information sharing and dynamic capabilities for each role in the supply chain, are insufficient. The purpose of this paper is to explore and evaluate effect of ICT utilization capabilities, including 'ICT internal cooperative capabilities' and 'ICT operational flexibility capabilities', on RTE capabilities (flexibility, visibility and prediction) and supply chain performance. To validate the research model proposed in the study, survey was conducted on companies using ICT along the supply chain of manufacturing industries. 216 data were used, SPSS and AMOS were used for the analysis methods. Study results showed that ICT internal collaboration capabilities affect agility, one of RTE capabilities, but not visibility and prediction, and ICT operational flexibility capabilities have affected all three RTE capacities. And, RTE capabilities had a huge impact on supply chain performance as expected. In this paper, it has been found that the ICT capabilities in manufacturing are an important factor in improving RTE capabilities that are important in the supply chain and improving the performance of the supply chain.

The organizations in the competitive business environment are under pressure of handling internal management processes as well as external supply chain issues. In addition, the paradigm of supply chain management (SCM) has been shifted from static to dynamic problems. For the efficient SCM, organizations should be a RTE (Real Time Enterprises) that views entire supply chains as a single entity. In this paper, the agent system that makes RTE and dynamic supply chains possible is developed. Then, the developed agent system is verified in the TAC SCM(Trading Agent Competition Supply Chain Management) experimental environment and a dashboard is also developed for monitoring management activities of supply chains. The contributions of this paper are as followings. First, unlike the previous agent systems, the suggested agent system in this paper provides autonomy and scalability using SOA. Second, this suggested model for dynamic environment can be applied for the development of software supporting a SCM.

The purpose of this study is to identify and comprehensively explain the SCM-related factors involved in the realization of RTE, including the quality of information concerning SCM, the quality of SCM partnerships, and relationship controlling factors (planning control, behavioral control, and outcome control). This study systematizes the interactions among these factors into a form of a model, elucidating how these interactions affect and shape RTE characteristics. To validate the research model proposed in the study, filed survey was conducted with 79 staffs in Korean company using SCM. The findings of the study can be summarized as follows: First, the quality of information concerning SCM had significant effect on the quality of SCM partnerships, planning control, behavioral control, and outcome control. Not only does the quality of SCM information directly influence the quality of SCM partnerships, planning control, behavioral control, and outcome control; but it also indirect influence on forecasting, agility, and visibility of SCM though its influence on the different forms of relationship control. Second, the quality of SCM partnerships also had significant effect on planning control, behavioral control, and outcome control. In addition to directly influencing these forms of relationship control, the quality of SCM partnerships also indirectly influenced forecasting, agility, and visibility though its influence on relationship control. Third, planning control significantly influenced forecasting, agility and visibility. Fourth, behavioral control significantly influenced forecasting, but neither agility nor visibility. Fifth, outcome control had significant influence on forecasting, agility, and visibility.

A design of an industrial microcomputer control system for an one-through tube boiler using oil is presented. The microcomputer system is based on standard iSBC 88/40 board. The software consist of a RTE(real time executive) and application tasks. The designed control system saves fuel and gives a more reliable over-all operation.

본 연구는 실시간 기업 (Real-Time Enterprise : RTE)의 핵심성공요인(Critical Success Factor : CSF)을 도출에 관한 내용으로써 기존에 연구되었던 '시스템 사고로 분석한 RTE 주요성공요인'의 연구 방법론을 개선하기 위해 동일주제로 연구되었다. 본 연구에서 도출된 성공요인의 결과를 기존 연구와 비교하였을 때 기존보다 크게 개선된 바는 없지만, 연구방법론 측면에서 시스템 다이내믹스의 정책지렛대라는 문제해결 방안도출 방법론을 활용함으로써 기존보다 객관화된 요인 도출과정을 설명할 수 있었다. 본 연구는 기존에 연구되었던 정재운 외(2006)의 '시스템 사고로 분석한 RTE 주요성공요인'의 내용을 개선하기 위한 것으로써 기존 연구의 내용 및 내용 전개방식의 상당부분을 별도의 표기 없이 참조하고 있음을 서두에 밝혀둔다.

Owing to a real-time innovative infrastructure driven by destructive technology revolution, the business environment has been changed dramatically. In order to respond fast to a continuously and unpredictably changing business environment, the business entities, such as business process participants, customers, distributers, and partners, should have an agile paradigm which is able to acquire and share the real time information adaptively. As a 21st century business paradigm having such adaptability and responsiveness has been introduced and called the "Real-Time Enterprise (RTE)" strategy. In this paper, we investigate the various innovation cases adopting the RTE strategy. After briefly addressing the concept and the value of RTE strategy, we discuss the models and the frameworks used in outstanding international and domestic enterprises. We believe that this case study can provide a good guide to many enterprises planning to adopt a RTE strategy for building competitive advantage in today's world of global competition.
