RELIABILITY BY DESIGN

DFMEA at system level

The aim of DFMEA analysis at system level is to study all consequences on the vehicle (functions impacted, system behaviour) in the case of any component failure or any missing/no correct signal or shared information. It does not include the consequence of any failure on the component behaviour itself. Altran consultants perform DFMEA analysis in three phases:

Our Focus

Preliminary risk analysis
 Functional analysis
 Inter-system distributed functions analysis
 Definition of Major unwanted events
 Definition of occurrence probability requirement for major unwanted events
 Risk analysis and reliability definition for major unwanted events

Second phase of DFMEA analysis at system level
 Definition of minor unwanted events
 Definition of occurrence probability requirement for minor unwanted events
 Risk analysis and global reliability definition (minor and major unwanted events)
 FMECA document creation for functional FMEA analysis

Our Deliverables
 DFMEA document (.xls file or any software tool like IQ-RM)
 DFMEA report
 Tech/job transfer evaluation form (team assessment)
 Status of technical and system recommendations
 Boundary and parameter diagram (AIAG standard or other)
