System Reliability Toolkit-V
The System Reliability Toolkit provides technical guidance in all aspects of system reliability, addressing both software reliability and human factors to better reflect the changing requirements of defense community. Learn more and order the System Reliability Toolkit-V.
The Influence of Reliability, Maintainability, Quality, Supportability and Interoperability on System Affordability
This publication, reflecting the specific mission of the Reliability Information Analysis Center (RIAC), discusses how the effective application of Reliability, Maintainability, Quality, Supportability and Interoperability (RMQSI) tools and processes will ensure that essential warfighting capabilities are delivered that meet system suitability requirements at the most affordable cost. The publication describes how each of the RMQSI disciplines impacts the overall affordability of a system during the evolving phases of its life cycle. Learn more.
Warranty Calculator
The Warranty Calculator was developed to provide automated calculations and comparisons for ten different warranty types in common use. The tool also includes data, information and references that provide further guidance for over 30 additional warranty types. Strategic warranty planning can increase customer confidence, reduce operational costs and provide the opportunity to generate revenue. Effective warranties integrate reliability, maintainability, supportability, availability, and life-cycle costs to arrive at optimized solutions. Learn more and try the warranty calculator for free.
Techniques to Evaluate Long-Term Aging of Systems (LAST)
The objective of this report is to highlight the impact of long-term aging effects on parts, assemblies and equipment by investigating characteristics of aging as they impact specific material classes. Learn more.
Supportability Toolkit
The Supportability Toolkit was developed as a guide for government, government contractors, and commercial industry. It provides common sense, up-to-date information for planning and carrying out those activities needed to develop supportable system and products throughout the life cycle of an item. Limited supply.

Reliability Toolkit: Commercial Practices Edition

Articles
Interference Stress/Strength Analysis
In simplest terms, an item fails when a stress to which it is subjected exceeds the corresponding strength. In this sense, strength can be viewed as “resistance to failure.” Good design practice is such that the strength is always greater than the expected stress. The safety factor “η” can be defined in terms of strength… Read More
System Spares – What’s the “Right” Answer?
Manufacturers are often faced with questions such as: How often will my system fail? How many spare parts should I stock? How confident am I that I will have enough spare parts? Read the article to learn more about answering these questions.
