SEVILLA JUAREZ, Edgar  e  ESCOBAR TOLEDO, Carlos Enrique. The Efficiency of Preventive Maintenance Planning and the Multicriteria Methods: A Case Study. Comp. y Sist. [online]. 2008, vol.12, n.2, pp.208-215. ISSN 2007-9737.

The objective of this work consists in the analysis of reliability in process plants in order to manage the failure risks and avoid them considering the probability of failure among other important criteria. The preventive maintenance is an important function for the better operation of any enterprise; we propose the ranking of process equipment according with their criticality for the operation plant to get a good preventive maintenance planning. The subjacent hypothesis is that decision makers should recognize that preventive maintenance planning does not have a single criterion as for example, costs or time, but are multicriteria by nature. To show how this methodology functions, naphtha and intermediate distillates Hidrodesulfuration Plant is used as a case study. The obtained results are the ranking of the process equipment; besides the parametric study that shows: the lower the budget assigned to preventive maintenance, the bigger the economic loss.
