Abstract

DURAN, Orlando M.; GONZALEZ-PRIDA, Vicente; CRESPO, Adolfo  and  GUILLEN, Antonio. Throughput based Prioritization of Physical Assets in a Crushing Plant. Inf. tecnol. [online]. 2019, vol.30, n.2, pp.45-56. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642019000200045.

A physical assets prioritization technique is proposed. The technique is based on the contribution that each equipment makes to global throughput. The proposed technique is based on the Overall Throughput Effectiveness (OTE) and relates the availability of each equipment, its utilization index with the throughput of the entire system. The hypothesis is that, from the point of view of maintenance, equipment can be ranked according to the impact that their unavailability generates in the performance at the factory level. Through a case study, based on a Chilean comminution plant, the viability of the technique and the possibility of analyzing the trends that the equipment's impacts show over time are demonstrated. It is concluded that the technique can be used to define maintenance policies, allocate resources and review operational decisions, in terms of improving levels of use and availability.
