The purpose of this paper is to propose a novel process failure mode and effect analysis (PFMEA) approach for the reliable design assembly activities prevent product defects due errors during complex products. PFMEA approached as an integrated method that, in addition implementing recommended actions, supports worksheets, equipment, layout lines systems, early phase product. As result, innovati...

Abstract The interaction of the wheel and rail, being physical basis for movement trains, determines not only such important technical economic indicators railway transport as weight trains their speed, reliability operational life sets, but also foundations operation - safety train traffic.
