Abstract

The blackboard problem solving architecture has been used in a number of real-time and near real-time domains with some success. The architecture is usually employed when control becomes complex. The control component of a blackboard system is centralised and combines both local and global control. In this paper, a system is described which distributes control across the blackboard. The system, CASSANDRA-ll, has been used in the controlled airspace monitoring domain. CASSANDRA-ll is a distributed system in which the usual abstraction levels of the blackboard are replaced by level managers. Level managers contain schedulers which make control decisions only for their own level manager. Global control is achieved by a separate scheduler.
