Maintenance systems are important for maintaining machines in operational status, reducing the associated costs, and for improving the quality of services and products. Productivity of a preventive maintenance (PM) program is evaluated based on several indices. Indices are monitored periodically to reflect corrective action in a PM program. Traditional approaches in monitoring indices are to compare them against available standards, or to implement run charts. Following disadvantages of these two approaches, this study proposes statistical quality control charts to monitor the indices. The proposed approach has been implemented in a domestic company. The observed results over a ten months period favorably compete against the traditional approaches.
