Abstract: The paper presents a methodology and Decision Support System (DSS) for the establishment of spare parts criticality with a focus on industrial unplanned maintenance needs. The obtained criticality is used to rationalise the efficiency of the plant spare parts inventory. Through a top-down Failure Modes Effects and Criticality Analysis (FMECA) that is appropriately adapted to the unplanned maintenance requirements and through the introduction of the Component Dynamic Criticality concept, the components of an industrial production facility are ranked. For those with criticality lying above a calculated threshold, additional spares are suggested to be kept in the plant spare parts inventory. An application example demonstrates the method.
