The Influence of Reliability, Maintainability, Quality, Supportability and Interoperability on System Affordability

The Influence of Reliability, Maintainability, Quality, Supportability and Interoperability on System AffordabilityThis 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.

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.
