REVIEWS AND CASE STUDIES: Study and analysis of maintenance performance indicators (MPIs) for LKAB A case study

摘要

The purpose of this case study is to identify and develop maintenance performance indicators (MPls) for a mineral processing plant producing high quality iron ore pellets, as well as studying and analyzing the short plant stops and planned maintenance stops. An action research approach was adopted for this study, with interactive process of interviews. The existing MPls are analyzed and a set of MPls are developed to measure the performance of balling area of the pelletization plant, where the effect of shorter stops in the process have been studied, analyzed and measured, and linked to the management's objectives. The utility of the MPls are tested and validated within the framework of a multi-criterion and hierarchical maintenance performance measurement (MPM) framework. The plant stop data of the plant were collected and analyzed for MPls and for maintenance decision making. Some other criteria were also considered from a holistic, integrated and balanced viewpoint in the model.
