Abstract

In industry, production processes and assets are constantly evolving, Thus, continually improving and updating them is essential to their sustainability. This work intended to apply a set of methods and philosophies to improve the Preventive Maintenance Management process in a case study company dedicated to the development, production and maintenance of power and distribution transformers. Thus, a Action - Research methodology was used. After identifying the main problems, a mixed maintenance strategy based on Reliability Centered Maintenance (RCM) and Total Productive Maintenance (TPM) was applied. The following achievements were obtained by this work: (a) method of grading equipment critically based on its importance to the production process was developed and implemented;(b) a new flowchart of decisions and actions was developed for Preventive Maintenance Plan Management; (c) a reduction of the waste time in Preventive Maintenance (PM) was obtained; (d) the implementation of Autonomous Maintenance (AM) resulted in a reduction of 66% in equipment failures; (e) a set of new Key Performance Indicators (KPI´s) were introduced; (f) maintenance plans compliance rates increased by 12%. At the end of the work a reduction of € 120 060 could be achieved. Thus, the main contribution of this work was to show that bringing to the action different tool together in an organized way and share the information and responsibilities with the workers can result in important savings to the company, becoming the maintenance function more effective.
