Assembly reliability evaluation method (AREM)

This paper introduces an effective new design-for-quality tool called AREM that visualizes assembly fault potential. Its evaluation formula is constructed on a fault occurrence model and enables quantitative evaluation of the fault generation potential of both product and assembly shop. The distinctive features of AREM are:(1) visualization of parts and operations having a high fault probability detection capability; (2) easy input by symbol selection as well as simultaneous assemblability evaluation; and (3) shop reliability, as well as product reliability, can be evaluated quantitatively. The method can be integrated with other DFX tools such as the assemblability evaluation method (AEM), and the recyclability/disassemblability evaluation method (REM/DEM) to realize a comprehensive production design evaluation system.
