  • One of the consideration issue in implementation and maintanence of CIM(Computer Integrated Manufacturing) database is exchange and sharing of information between heterogeneous databases. For efficient operating of SIM systems, it must be able to organize and to manage the information. In this paper, we propose method that can make enhance the efficiency of CIM database, classfying the data in database using self organize neural network to each database systems, and computing between classfied heterogeneous database using extended operator that is defined.

  • A CIM implementation case is introduced in this paper. It is accomplished through the integration of two fundamental approaches to production planning and control; JIT and MRP. The resultant system is a hybrid where some JIT methodologies prevail, but the benefits of the MRP are also required. A new BOM structure called 'Family-BOM' is designed for the load leveled production with small lot size and the synchronized production. The overall production planning concept is described with actual data.

  • Manufacturing companies must have close relationships with cooperative companies and customers under dynamic market surroundings. Not only product life cycle, but also the allowed period between development of product and sale becomes shorter. In spite of these situations, most manufacturing companies have insufficient capabilities of the information technology and data exchange formats between companies are so different. Thus, there exists a limit on the efficient management of companies. These problems in manufacturing companies could be solved by CALS. Through CALS the company responses quickly to customer demand, transfers this information to manufacturing systems automatically, and distributes products at appropriate time In short, CALS is a strategy to distribute products satisfying with quality, cost and delivery. And up to now, most manufacturing companies have proceeded CIM systems. In this paper, an approach for the efficient building CALS system through extension of CIM in the manufacturing companies is proposed.

  • The exchange of information with legacy systems is a main issue in the era of SMARTGRID. Because WAMAC(Wide Area Monitoring and Control) system has monitoring function, as well as control function, it is very necessary for WAMAC to exchange data and information with SCADA(Supervisory Control and Data Acquisition) / EMS(Energy Management System). IEC 61970 CIM(Common Information Model) is an abstract model that represents all the major objects in an electric utility enterprise typically involved in utility operations. In this paper, a proposal that adopting CIM to WAMAC model be submitted so that the integration of various legacy system and application for itself be able to be flexible.

  • 선진국에 비해 원천 설계기술의 낙후와 저임금을 무기로 하는 후발국의 공세에 진퇴양난의 위 기에 당면한 국내 전자업계는 80년대 후반부터 본격적으로 소개되기 시작한 컴퓨터 통합제조시 스템 즉 CIM(computer integrated manufacturing) 시스템에 대한 많은 관심과 걔와 함께 이의 구축을 서두르고 있다. 그러나 CIM시스템이 특정기술들의 집합으로써 표현되는 구체적 모습을 갖춘 시스템이라기보다는 기업의 경영목표나 비전을 달성하기 위한 전략적 도고로서 이해되어야 할 것이며, 또한 아직까지 선진국의 기업에서조차 이상적인 CIM시스템을 구축하기 위하여 계 속적 노력을 진행중으로서, 구축방향이나 범위는 기업의 전략에 따라 크게 상이할 것으로 생각 된다. 이 글에서는 이상적 CIM시스템을 지향하는 자사의 신생산시스템에 대한 추진배경 및 전략, 그리고 이에 대한 구체적 사례를 간략히 소개하고자 한다.

  • Computer Intergrated Manufacturing (CIM) is an emerging technology which aims at the total automation of a manufacturing system. Despite the extensive research on CIM in this decade, total automation seems to be far from reality for many reasons. In this study, the problems of implementing a CIM system are analyzed and a solution method is suggested. A set of software has been developed and tested for a workstation cotroller which controls closely integrated equipment in the low level of a flexible manufacturing system. The functions of the programs are communications between machines and computers and control of workstation scheduling. The software group is developed on IBM OS/2 operating system with 'c' language to enhance the portability. The usage of the software is presented to users through the Presentation Manager which is menu handler of OS/2 system. Although the software is developed for limited machine equipment, the scheme can be adopted to various machines due to the generality.
