A Distributed Blackboard Architecture
Iain Craig · Warwick Research Archive Portal (University of Warwick) · 1987
This paper describes a problem solving architecture derived from the blackboard model of problem solving. The architecture introduces the concepts of Level Managers and local control into the blackboard architecture. The architecture is suited to distributed problem solving. The major features of the architecture are described and the restrictions imposed upon components by an inherently distributed, asynchronous problem solving environment are discussed. An experimental system, called CASSANDRA-II, is described, as is the control component derived in an exercise to re-design HASP/SIAP in terms of the new architecture. The CASSANDRA-II system implements the features of the architecture in the context of intelligent monitoring of aircraft movements in controlled airspace.
