Intelligent scheduling of a group of elevators

An elevator group control system for the traffic control of elevators in a multistory building is studied. A blackboard architecture is used for the development of the control system. The performance of the elevator system is measured by an indicator called system response time. A blackboard system was implemented in Prolog and the opportunistic type of problem solving offered by the blackboard architecture has succeeded in obtaining a solution. The opportunistic type of problem solving was applied to the task of real-time scheduling of elevators which is a complex and ill-defined problem. Simulation results which illustrate the operation of the blackboard system are presented
