Designing a Total Productive Maintenance (TPM) Management Model Using a Combined Approach of Factor Analysis and Interpretive Structural Modeling (ISM) in the Power Distribution Companies of Northwest Iran

The aim of this study is to design a Total Productive Maintenance (TPM) management model using a combined approach of factor analysis and Interpretive Structural Modeling (ISM) in the power distribution companies of northwest Iran. This research is conducted within the power distribution companies of the northwest region, selected as the pilot area. Identifying the optimal maintenance strategy and selecting the most effective TPM management model are of significant importance. The results of this research will be provided to Tavanir and the Ministry of Energy for potential implementation in other affiliated companies. From a spatial perspective, the quantitative data pertains to operational data from the power distribution companies in the northwest region. The statistical population includes both experts and the self-assessment segment of all specialists and maintenance, repair, and warehouse personnel within these companies. Temporally, the data includes operational records from the inventory, accounting, and process systems of the power distribution companies for the years 2017 to 2022. The findings of this study indicate that the initiation of the TPM process should begin with enhanced management and leadership in maintenance and repair, followed by attention to reliability improvement, feedback and system outcomes, human resources and employee skills, and quality preservation in the process of preventive maintenance. Additionally, work processes, organizational structuring, task force formation, planned preventive maintenance, safety and health preservation, equipment and warehouse management, resource and contract management, adoption of preventive maintenance technologies, expansion of automation systems, self-controlled maintenance and repair, and ultimately, understanding the appropriate framework for TPM in power distribution companies—based on the insights of experts and system specialists—should be considered.
