Attention focussing and anomaly detection in real-time systems monitoring

In real-time monitoring situations, more information is not necessarily better. When faced with complex emergency situations, operators can experience information overload and a compromising of their ability to react quickly and correctly. We describe an approach to focusing operator attention in real-time systems monitoring based on a set of empirical and model-based measures for determining the relative importance of sensor data.

Scheduling Nonconsumable Resources

Users manual describes computer program SWITCH that schedules use of resources - by appliances switched on and off and use resources while they are on. Plans schedules according to predetermined goals; revises schedules when new goals imposed. Program works by depth-first searching with strict chronological back-tracking. Proceeds to evaluate alternatives as necessary, sometimes interacting with user.

Dynamic Replanning System

Artificial-intelligence computer program for planning automatically changes plan when conditions warrant. System uses planning software called SWITCH. Contains replanning input generator. Replanning done only for situations in which SWITCH has made plan but goals have changed. System assumes original knowledge base correct, which often is not the case. Future development aimed at compatibility with changing knowledge bases.
