This paper discusses the performance of production processes and maintenance policies in industrial environments from an analytical point of view.
Particularly, the paper analyzes those mechanisms for assets hierarchy that allow discretizing that equipment considered critical, i.e. equipment with a high impact in case of failure, whether in production, costs, human and/or environmental safety. Therefore, a great amount of resources should be assigned. For this purpose, firstly it is made a review of the main techniques used in the ranking of existing industrial assets in the literature. After that, a methodology is proposed in order to simplify the optimal selection of criticality analysis techniques, whose implementation is more appropriate for a particular industrial environment and based on a set of variables. This methodology uses decision trees together with dichotomous type questions. Finally, the proposed methodology is applied to a real case related to a production plant of sulfuric acid, located in Chile. The methodology
implementation has been useful to identify the most critical plant equipment in order to make appropriate decisions.
