SELECTING the most appropriate maintenance strategy provides significant savings in lost production cost, power consumption and lifecycle costs. In this research, a bi-level sustainability-based maintenance strategy selection framework is proposed under uncertain judgments of decision makers. In the first step, all related sustainability criteria which can affect maintenance strategy selection process is determined and then factor analysis method has been applied to identify the underlying structure among these criteria. In the next step, fuzzy VIKOR method is applied to select the best maintenance strategy. The proposed framework is illustrated through a case study in a manufacturing firm.
