Performance Monitoring with Application of Reliability Growth Analysis

Reliability growth analysis is a popular tool in monitoring reliability changes over time. The methods used include Duane plots and the Army Materiel Systems Analysis Activity (AMSAA) model. The reliability growth analysis is traditionally applied to the time domain of failure. The amplitude of failure is not considered. For equipment or processes with same MTBF should not be treated with the same priority without looking into loss of opportunity in wealth creation. This research proposes the application of reliability growth method to failure losses in unit of production loss for monitoring changes in magnitude of production loss due to failure events. In conjunction with reliability growth in time domain, a new analytical visualisation of reliability assessment, named Reliability Quadrant Graph, is proposed. This research provides a new way for high level reliability performance monitoring.
