철강제조업 정보SYSTEM에 CIM(Computer Integrated Manufacturing)을 적용한 결과 설비와 정보의 자동화와 더불어 인력자원의 성력화에 의한 인원 및 자원의 절감등이 주요 효과로 나타났다. 영업관리, 자재관리, 생산관리, 출하관리, 설비관리를 시스템화하여 수요예측에 의한 자재·제품·재고 보유량을 감소할 수 있었으며, 원활한 공정진해응로 제조기간의 단축이 가능하였다. 또한 효율적인 설비관리, 정보의 공유 및 실시간 제공으로 신속한 의사결정지원등의 직·간접적인 효과가 나타났다.

중소기업의 기술혁신은 제품의 생산성을 높임으로써 궁극적으로는 새로운 영역에의 참여와 고용창출 효과를 가져올 뿐만 아니라 국가의 수출경쟁력에 이바지하는 기여도가 매우 높다. 중소기업은 규모가 작고 유기적인 조직구조의 특성상 탄력적으로 기술혁신에 대처할 수 있는 유리한 면이 있지만, 국내의 중소기업 기술혁신은 매우 열악한 상태이다. 따라서 대기업을 위주로 형성되어 있는 통합생산관리시스템(CIM)의 개념을 도입하고 산업용네트워크와 통합생산관리시스템을 적용하는 중소기업 기술혁신의 추진전략에 대해 설명하였다.

본 논문은 CIMS에서 적응되는 ARMA 공정제어의 새로운 3단계절차를 제안한다. 첫번째 단계는 다변량 ARMA모델을 식별하여 모수를 추정하고, white noise로 진단된 잔차 series에 대하여 다변량 제어통계량(즉, 다변량 Hotelling T$^2$통계량, 다변량 CUSUM, 다변량 EWHA 통계량, 다변량 MA 통계량)등을 계산한다. 마지막으로 본 논문에서 제안한 8가지 다변량 제어통계량을 상호비교하여 이상점을 발견한다.

This paper describes the design and realization of an extra high frequency band $8{\times}8$ microstrip Butler matrix. Operation at 36 GHz is achieved with a frequency bandwidth exceeding 400 MHz. The circuit is implemented on a bi-layer microstrip structure using conventional manufacturing processes. This planar implementation of a Butler matrix is a key component of a switched beam smart antenna with printed antenna elements integrated on-board. Conception details, simulation results, and measurements are also given for the components (hybrid couplers, cross-couplers, and vertical inter-connections) used to implement the matrix.

Expert system is an effective approach for quality system to be automated and thus to be an essential integrating mechanism in any move towards CIM(Computer Integrated Manufacturing). A quality control expert system is introduced and its relationship to CIM is illustrated in a case study. Process control expert system developed by Kim and Sin[6] has been improved via ODBC(Open DataBase Connectivity) for efficient information network, graph representation using Windows API for rapid response and some new rules for identification of patterns in control charts.

This study investigates the reasons why firms choose to adopt CIM technologies and the decision making process involved in justifying them. In addition, factors that contribute the successful implementation of CIM are identified. Finally, this suggests a strategical model based on the above result of analysis with investigating the justification, evaluation, implementation, and adaptation of CIM.

Most recently, offshore Engineering & Construction field is concerned about integration management technology such as CIM(Computer Integrated Manufacturing), PDM(Product Data Management) and Enterprise Information Engineering in order to cope with the rapid change of engineering and manufacturer specification as per owner's requirement during construction stage of the project. System integration and integrated data modeling with relational database in integration management technology improve the quality of product and reduce the period of the construction project by reason of owing design information jointly. This paper represents the design methodology of system integration using Business Process Reengineering by the case study. The case study is about the offshore plant material information process from front end engineering design to detail engineering for the construction and the basis of monitoring system by integrating and sharing the design information between the 2D intelligent P&ID and 3D plant modeling using relational database. As a result of the integrated data modeling and system integration, it is possible to maintain the consistency of design process in point of view of the material balancing and reduce the design assumption/duration. Near future, this system will be expanded and connected with the MRP(Material Requirement Planing) and the POR (Purchase Order Requisition) system.

For the effective operation of manufacturing system, FMS(Flexible Manufacturing System) and CIM(Computer Integrated Manufacturing) system are developed. In these systems, a machine tool is the target of integration in last 3 decades. In nowadays, the conventional concept of machine tools is changing to the autonomous manufacturing device based on knowledge-evolution through applying advanced information technology in which open architecture controller, high speed network and internet technology are contained. In this environment, a machine tool is not the target of integration but the subject of cooperation. In the future, a machine tool will be more improved in the form of a knowledge-evolution based device. In order to develop the knowledge-evolution based machine tools, this paper proposes the structure of knowledge evolution in M2M(Machine To Machine) and the scheme of a dialogue agent among agent-based modules such as a sensory module, a dialogue module, and an expert system. The dialogue agent has a role of interfacing with another machine for cooperation. To design the dialogue agent module in M2M environment, FIPA-OS and ping agent based on FIPA-OS are analyzed in this study. Through this, it is expected that the dialogue agent module can be more efficiently designed and the knowledge-evolution based machine tools can be hereafter more easily implemented.
