Heterogeneous Integration Architecture for Intelligent Control Systems

1992-1994 / ESPRIT III 1803

HINT was an ESPRIT II project (#6447), partially funded by the Commission of the European Communities, which produced a coherent framework for integrating different computer-based control techniques, in particular AI ones, in order to overcome the obstacles in the control of complex continuous processes and to provide solutions to process control problems which require the kind of intelligent supervision that is presently carried out by human operators.

The HINT Project tried to cope with a recurring problem in complex process control: the need of integration of heterogeneous software components in a complex process control system. These components are new or legacy components performing activities in restricted areas: covering partial domains, performing simple functions and using single technologies.

The results from the HINT Project were:

  • An integration methodology
  • An integration architecture
  • A set of problem solving components using different reasoning mechanisms.
The diagram shows the overall HINT architecture for integrated intelligent process control.
