Modified failure mode and effect analysis (FMEA) model for accessing the risk of maintenance waste

Abstract

The existence of methodology for ranking and mitigating the risk of non-value added activities in manufacturing strongly support the realization of sustainable manufacturing practice. However, endeavours to create tools and methodology to rank the risk of non-value added activities are mostly devoted on product design and manufacturing and very rarely in maintenance engineering discipline. Motivated by such scarcity, the goal of this study is attempted to develop a modified FMEA (Failure Mode and Effect Analysis) as means to access the criticality of waste in maintenance operations. In an attempt to facilitate decision makers in appraising the criticality of maintenance waste occurrence, an improved model for ranking the risk of maintenance waste mode by using Waste Priority Number (WPN) is proposed
