An information system for operations management: co-ordination and integration

Wide implementation of computer-based operations management systems now faces a new information problem. In many manufacturing companies the management system consists of several disconnected subsystems. Each subsystem uses its own database, which is physically situated in a PC of a specific manager. Each subsystem represents one or several managerial problems, which are being solved regularly at given intervals of time. The multiple data transfers between the databases are performed manually, and this reduces the efficiency of the system and the possibilities for its development, Implementation of file servers only place databases under one roof but does not automatically provide transfer of data. To unite the system effectively in a network environment, a scheduling model has been developed, which uses an information model of the operations management process and a system clock as a basis for its functioning.
