Abstract
Maintenance plays an important role in achieving the organizational goals so that the measurement of its effectiveness and efficiency has become an essential element of industrial strategy. In literature several Maintenance Key Performance Indicators (MKPIs) are proposed but none structured approach is suggested to select the best set of MKPIs able to synthetically describe a specific maintenance context. The paper proposes a structured methodology for the maintenance performance measurement by means of MKPIs. Firstly, a multi-level hierarchical framework able to synthesize the most meaningful perspectives affecting the performance of the maintenance process is designed. Successively, some MKPIs proposed in the literature are assigned to the hierarchical framework and ranked by an Analytic Hierarchy Process-based approach. A procedure to deal with incomplete and inconsistent pair-wise comparison matrices is proposed. Finally, a mathematical model is formulated to select the set of MKPIs representing the best compromise between the completeness and the conciseness of the returned information
