Evaluation of maintenance performance in Metalworking Company: a case study and proposal of new indicators
In Brazil, companies work primarily with preventive and predictive maintenance (BRAZILIAN…, 2009). The maintenance sector has been strategic for companies to achieve results efficiently and with planned costs. However, the maintenance indicators are not usually analyzed. The purpose of this study was to analyze the maintenance performance of a metallurgical company and to identify potential maintenance indicators that may be adopted by that enterprise. Thus, it is expected that the maintenance sector be more competitive and efficient, contributing to the achievement of results. In order to do so, data and time periods of maintenance, nature of maintenance, and service plan for preventive maintenance were collected from the company’s control system for the time period of one year. After that, the data were catalogued onto a spreadsheet. Then, the suggested indicators that were relevant to the availability of equipment for production as well as to the percentage of hours worked in preventive/predictive maintenance compared to corrective maintenance were analyzed. Preliminary results showed that the programming methodology adopted for maintenance in this study improved the availability of equipment for production and also the time of corrective maintenance, which it is of great importance.
