Estimating Cost and Schedule of Reliability Improvement

Abstract

We extend a well-established model of reliability growth in a reliability improvement program, the Army Materiel Systems Analysis Activity Maturity Projection Model (AMPM), to include a model of the program's cost. We show how the extended model may be used to plan cost-optimal or schedule-optimal integrated programs of reliability improvement and testing, from early design through developmental and operational testing, and illustrate the process with an example from an actual program.
