Unformatted text preview: SYSTEM AND SOFTWARE RELIABILITY ASSURANCE NOTEBOOK Produced For Rome Laboratory By Peter B. Lakey, McDonnell Douglas Corporation, St. Louis, MO Ann Marie Neufelder, SoftRel, Hebron, KY FSC-RELI ii FOREWORD This notebook provides a reliability assurance methodology to predict and estimate the reliability of systems that employ both hardware and software subsystems. Since the methods used to predict the reliability of hardware systems are well established, this notebook concentrates on the methods to predict and estimate the reliability of software configuration items and methods for combining hardware and software reliability metrics into an overall system parameter. iii System and Software Reliability Assurance Table of Contents 1.0 INTRODUCTION ............................................................................................................1-1 2.0 APPLICABLE DOCUMENTS .........................................................................................2-1 3.0 DEFINITIONS AND SYMBOLS .....................................................................................3-1 3.1 Definitions of Terms .....................................................................................................3-1 3.2 Abbreviations ...............................................................................................................3-4 3.3 Mathematical Symbols..................................................................................................3-5 4.0 OVERVIEW 4.1 System Reliability Prediction and Estimation Program...................................................4-1 4.1.1 System Modeling. ................................................................................................4-1 4.1.2 System Reliability Allocation................................................................................4-7 4.1.3 System Reliability Prediction................................................................................4-8 4.1.4 System Reliability Growth....................................................................................4-8 4.1.5 System Reliability Qualification Testing................................................................4-9 4.1.6 System-Level Failure Reporting and Corrective Action System (FRACAS)..........4-9 4.2 Hardware Reliability Prediction and Estimation Program .............................................4-9 4.2.1 Hardware Reliability Modeling.............................................................................4-9 4.2.2 Hardware Reliability Allocation..........................................................................4-10 4.2.3 Hardware Reliability Prediction..........................................................................4-10 4.2.4 Hardware Reliability Growth..............................................................................4-10 4.2.5 Hardware Reliability Qualification Testing. ........................................................4-10 4.2.6 Hardware FRACAS. ..........................................................................................4-11 4....
