A reliability model mathematically defines the interdependencies between hardware/ software/human elements and their combined contributions to failure. A prediction calculates failure rates using that model so that a reliability metric can be quantified to assess design tradeoffs, and as an estimate of operational reliability after a product is delivered.

What is it?
A reliability model mathematically defines the interdependencies between hardware/ software/human elements and their combined contributions to failure. A prediction calculates failure rates using that model so that a reliability metric can be quantified to assess design tradeoffs, and as an estimate of operational reliability after a product is delivered.
What’s the payoff?

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
Solving the Complex RBD-Series Parallel System with a Keystone Component
The general form of this type of reliability block diagram has two series circuits in a parallel arrangement combined through a center or “keystone” unit. You are often given the reliability of each block and asked to calculate the reliability of the circuit.
For example let’s say we are given the following five block arrangement pictured… Read More

Better Reliability Predictions Using Experience Data
There are many approaches that can be used to predict the reliability of an item. Sometimes when asked to provide a “quick estimate” of an item’s reliability, the use of field experience is overlooked, or if no failures have occurred, overly conservative estimates are made by assuming one failure. This article describes a simple approach… Read More
