Production Plan of Information Management System for Virtual Industry

摘要

The information management is a crucial mission for a virtual industry in such a competitive market environment. The typical characteristic of information management is distribution, autonomy and co-operation. Based on an on-going ESPRIT project (X-CITTIC), the author presents a distributed information management architecture for production planning and control in a virtual enterprises of semiconductor manufacturing. Object technologies are widely used in its design and implementation. A detailed structure of the components in the architecture, called information managers, is also suggested and introduced. Each information manager has three elements: a data object server, a database and a group of meta-objects. The information management can provide not only basic services (e.g. read and write) but also advanced services (e.g. notification, security control, subscription and data sending). Finally the present X-CITTIC information management system is detailed introduced.
