Objectives and Approach

This project used knowledge-based techniques in order to make modern production philosophies such as OPT, JIT and LOP available and operational at shop-floor level.

The project adapted existing architectures (CIM shell), building expert systems and design tools for workcell and shop controller realisations (distributed CIM controller network), testing the CIM controllers in small, medium and large batch manufacturing (factory implementation), developing controllers and tools towards marketable products including dedicated controller chips (CIM products).

Progress and Results

Results of the project and several prototype systems have been installed at Philips, Pirelli and BICC factory environments. These prototypes are being used as decision aids for dynamic scheduling, planning, diagnosis and maintenance-related problems.

Those CIM modules which successfully pass the factory tests will be further developed towards marketable products. Developments foreseen include:

PKAM and DNDS are dedicated software tools developed within the project to facilitate the design and implementation of the CIM system described above. These tools are part of the CIM shell, which contains:

The implementation of specialised AI hardware and software is often blocked by integration problems into the existing computer environment. The project also designed special CIM-AI chips and their integration into standardised (VME bus) computer systems. The extension by AI processor cards will open new real-time supervisory functions for expert systems on the shop-floor.
