Performance Evaluation of Dynamic Monitoring Systems: The Waterfall Chart

Summary: [This abstract is based on the authors' abstract.]The increasing use of computers to monitor the performance of complex systems calls for a methodology to evaluate the their performance. The waterfall chart, a three-dimensional representation of the probability of an alarm as a function of time and the condition of the system, is proposed. The chart shows the conceptual relationship between the cumulative distribution function of the run length and the power function. The chart's usefulness is demonstrated on an application to Page's one-sided Cusum algorithm, but it may be applied in general for any monitoring system.
