Abstract: Many people treated CIM as a model for future manufacturing system. However, there were few successful cases. Very often their failures were caused by the lack of top management support. Due to the fact that international competition becomes more and more vigorous, top management is beginning to look at CIM more seriously. Under these circumstances, the project of strategic implementation and justification of CIM in Hybrid Division was started. In this case, the CIM conceptual model was designed based on the proposed system in the technical paper by Jeffery and Michael from Westinghouse [1] with updated techniques, such as LAN and decision support systems, instead of direct linkage by HP 2250 and database system. The approach was emphasised on the shop floor control, and was targeted at improving production efficiency and product quality by the centralised information system. The proposed methodology was developed to fit the conditions of the company under discussion. It was of modular structure, and was modified from the proposed system in the technical paper by Eyada, Liu and Metcalf [2]. The proposed methodology emphasised on the management commitment, project team formation, implementation sequence and system concept. The tentative system design made use of a LAN system to provide communication among the Central Database System, Server, all control and office computers. The LAN system provides an internal router feature that allows the Server to be connected to the Central Database System, and making them appear as a logical network. Star topology is used to provide connection between the Server and all control computers, and Bus topology is applied to provide linkage between the Server and all office computers. The system also performs the on-line monitoring, generates the daily manufacturing schedule of each equipment, generates report on in-process control, machine performance, product status, etc. Since the technology of tele-communication and computer are already matured, the implementation of CIM system in Hybrid division is definitely feasible from the technical point of view. On the other hand, CIM will totally change the conventional practises of the company so much, so that the resistance to change from the end user cannot be neglected. However, basing on the proposed methodology, user involvement is heavily emphasised, so staff of those affected departments are included in the project team. Hence, it is expected that the effect of resistance to change on both management and staff will be minimised. Nevertheless, it is not possible to involve the production operators in the preparation of the whole project, the opportunity to minimize their resistance to change is to time the implement of the CIM system during the re-location of the factory. By that time they have to face a lot of new matters such as plant, machineries, staff and etc, so their resistance to the introduction to the CIM system will not be very serious. Finally, the conclusion drawn from the result of this study reinforce that : 1. the interpretation of CIM as an information system was correct; 2. the conceptual design model suited our application; 3. the proposed methodology fitted our conditions and 4. the whole project could be justified financially.
