Desarrollo de un análisis de criticidad para los equipos del área de líquidos y plásticos en la empresa Eterna S.A.

Abstract

In the following work, a criticality analysis was developed for the equipment that is part of the liquid and plastic production line at ETERNA S.A. First, a general description of the PET blow molding, conventional blow molding, plastic injection, liquid preparation, filling, capping and labeling lines, among other sub-processes, was made. Subsequently, the equipment and sub-equipment involved in the production line were characterized, detailing operating data. The information collected was compiled in parallel to the workflow of the area, analyzing the data obtained and defining the participation of each asset. Accessing the maintenance history of the equipment, supplied by ETERNA S.A., a previous classification of the data was made focusing on the main maintenance indicators for the elaboration of a matrix based on the frequency of events with which it is possible to develop the methodology of criticality analysis by points and Ciliberti's method. The criteria exposed in the procedure were developed for each equipment having the classification of high, medium or low risk, obtaining a hierarchy of criticality justified in the failure history and impact of the failure in the production line. The implementation methodologies will be shared with the area in charge of the company so that they can proceed with the execution of the analysis if required. Additionally, this resource can be an instructive that allows a new management in the methodologies applied for other plants of the company and in this way to appropriate tools in the maintenance area that are beneficial in decision making, resource utilization and improvement of indicators.
