Abstract:

  The purpose of this paper is to present an architectural pattern for
  the control component of a blackboard system. It builds on the model
  of dynamic control where a blackboard system has a repertoire of
  independent domain and control knowledge sources, a control plan
  expressing the system's desirable behavior, and a meta-controller
  that chooses at each point in time the currently enabled knowledge
  source that best matches the control plan. A system implementing
  this architectural pattern is able to dynamically change its control
  strategies as a response to unpredictable events.

  The architectural pattern is described according to the form used in
  the book of Frank Buschmann and his colleagues \cite{Buschmann}.
