Abstract

This paper proposes an audit methodology designed to provide savings in the allocation of resources for maintenance, in the form of activities, time, labor, spare parts and direct costs of corrective and preventive actions. Using graphs, this audit methodology analyzes the resources allocated to maintenance actions, and their consistency in terms of downtime and risk for critical failure modes. The description of the method is performed by a BPMN diagram including a format that summarizes the required input data. This audit methodology can be applied independently to assist in the fulfillment of organizational goals, or as part of an asset management system, as would be the PAS 55 standard.
