About RS

IEEE Reliability Society - Field of Interest

The Society is concerned with the strategies and the best practices for attaining, assessing, assuring, and sustaining system reliability throughout its life cycle.

(The following statements are provided to aid in the clarification of the purpose and the focus of the RS)

Reliability is a design attribute of a system (encompassing hardware, software, services and processes). Even though reliability is an intangible attribute, it is a true system performance measure. System reliability in this context implies the reliability of any product tier starting at the materials level, then the device / component level, then the assembly / unit / module level, to a system or system of systems. The term “system” is meant to be a broad term so that anyone within Reliability Engineering working on or with a product or process or service can be included in this Society.)

Additionally, by having Reliability as an attribute, with the Society’s broad perspective of the term, leads to the use of descriptive terms, such as: dependable, trustworthy, available, maintainable, reliable, fault-tolerant, graceful degradation, failure immunity, secure, safe, intuitive, sustainable, resilient, reliant, etc. Reliability is integral to Design, Availability, Maintainability, Testability, Diagnostics, Prognostics and Health Management, Integrity, Security, Quality, Supportability, Human Engineering, and System Safety. The Society membership encompasses engineers who are designing, analyzing, producing, and assessing some portion or level of a system, be it hardware, software, devices, processes, or materials. Reliability is also a type of metrology.

The Reliability Society provides a professional home for engineering communities or disciplines in these focus areas. Reliability applies scientific knowledge to assure a product will perform its intended function for the required duration within a given environment. This includes designing in the ability to maintain, test, and support the product throughout its total life cycle. Reliability is best described as product performance over time. This is accomplished concurrently with other design disciplines by contributing to the selection of the system architecture, materials, processes, and components -- both software and hardware; followed by verifying the selections made by thorough analysis and test.

The skills and knowledge required to achieve reliable products are:

  • statistical analysis,
  • product reliability modeling for selection of redundancy Vs component reliability,
  • trade study analysis,
  • reliability predictions,
  • worst case stress/tolerance/sigma design performance analysis,
  • engineering based physics of failure,
  • failure modes/effects/criticality analysis,
  • reliability test planning and testing -- product stress screening/ accelerated life/demonstration,
  • failure analysis,
  • maintenance concept definition,
  • maintainability analysis,
  • maintainability test planning and demonstration,
  • supportability analysis,
  • derating analysis,
  • human engineering analysis,
  • product safety analysis,
  • reliability/maintainability/system safety/ quality/logistics support/human factors/software performance monitoring, and
  • product effectiveness.

Reliability is a product design attribute that cannot be ignored! Every design has reliability characteristics - It is a critical ingredient of all designs created within all industries. It is far better to explicitly consider reliability than to ignore it and hope for the best!
