In 1993 the Automotive Industry Action Group (AIAG) first published an FMEA standard for the automotive industry. [17] It is now in its fourth edition. [18] The SAE first published related standard J1739 in 1994. [19] This standard is also now in its fourth edition. [20] In 2019 both method descriptions were replaced by the new AIAG / VDA FMEA ...
FMEA is a bottom-up, inductive analytical method which may be performed at either the functional or piece-part level. FMECA extends FMEA by including a criticality analysis, which is used to chart the probability of failure modes against the severity of their consequences. The result highlights failure modes with relatively high probability and ...
The Automotive Network Exchange is a private extranet initially set up and maintained by the Automotive Industry Action Group, [22] Telcordia, General Motors, Ford, and Chrysler. It was launched in 1995 for the auto industry with a stated goal of providing consistent, reliable speed and guaranteed security for data transmissions between the ...
VDA (Germany) AIAG (North America) AVSQ (Italy) FIEV (France) SMMT (UK) But due to this regulation a supplier needed to provide two different certificates for Daimler and Chrysler (VDA 6.1 for Germany and QS 9000 America), even though the supplier delivered only to a single company. These complexities accelerated the need for harmonization.
This classification helps defining the safety requirements necessary to be in line with the ISO 26262 standard. The ASIL is established by performing a risk analysis of a potential hazard by looking at the Severity, Exposure and Controllability of the vehicle operating scenario. The safety goal for that hazard in turn carries the ASIL requirements.
The analysis for DRBFM is modeled after a linkage between a good design review and FMEA. A comprehensive, well-done FMEA can be considered one of the inputs (plus many other preparations sheets defined in the methodology) to decide the scope of a DRBFM but an FMEA is not required since the focus is based on the changes and interfaces.
The initial FMEDA added additional information to the FMEA process. The first piece of information added in an FMEDA is the quantitative failure data (failure rates and the distribution of failure modes) for all components being analyzed.
The design or process controls in a FMEA can be used in verifying the root cause and Permanent Corrective Action in an 8D. The FMEA and 8D should reconcile each failure and cause by cross documenting failure modes, problem statements and possible causes. Each FMEA can be used as a database of possible causes of failure as an 8D is developed.
