Machine performance index (MPI): A method to evaluate the performance of mining dumper

Abstract

Efficiency and effectiveness of equipment play a dominant role in modern mining industry to determine the performance of mining equipment as well as mines. Greater the efficiency and effectiveness more productive is the organization (mine). As it is known that mining industry is a very capital intensive industry. Hence, a proper performance measurement is very necessary in this field. Since last many years, overall equipment effectiveness (OEE) has been used in different industries as a measure of performance, but due to limitations in the original OEE, it has been modified continuously time to time by different researchers and practitioners in the different field accordingly. Since, last two decades OEE has also been used in mining industry. This research assigns different weightage to different components by using analytical hierarchy process (AHP), and thereby determines the weighted OEE i.e., machine performance index (MPI). The main purpose of assigning the weightage is to show the influence of each component in the evaluation of OEE. In original OEE, the weightage given to each component was equal which was not justifiable logically. To check the applicability of this new method, a case study was done on dumper in an opencast coal mine of India. © 2019, Books and Journals Private Ltd. All rights reserved.
