Mission Reliability and Logistics Reliability: A Design Paradox
The goal of improving system reliability often presents a design paradox; “mission” reliability cannot be increased without simultaneously decreasing “logistics” reliability. When faced with the challenge of a system that has inadequate reliability to meet specification requirements, hardware redundancy is often implemented, leading to an improvement in one…  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…  Read More

Reliability Predictions: Parts Count, Part Stress, Pseudo Stress and Dormant
Reliability predictions are an important tool for making design trade-off decisions and estimating future system reliability. They are often used for making initial product support decisions such as how many spares are required to support fielded systems. Inaccurate predictions can lead to overly conservative designs and/or…  Read More

Reliability Knowledge? Who? What? Where?
This article is the first in a series addressing the availability of reliability knowledge, who has it and how you can take advantage of it to improve products and systems. Despite a broad interest in reliability, there is a general lack of coordination of the efforts of many disparate organizations dealing…  Read More

Understanding Your Product Through Reliability Modeling
A reliability model represents a clear picture of your product’s functional interdependencies providing a means to trade-off design alternatives and to identify areas for design improvement. The models are also helpful in:

Identifying of critical items and single points of failure
Allocating reliability goals to portions of the design
Providing…  Read More
