Abstract

The present titling work has as an aim to elaborate an auditing model which allows to evaluate the fixed assets maintenance management of the Cement Plant National Union (CPNU), Chimborazo Plant. To elaborate the auditing model, it was realised a compilation of theoretical criteria that must be included to a right maintenance management according to the international norms. The methodology used for the criteria selection for the auditing was the Delphi technique, that allowed to define the seven criteria which were used during the auditing to the maintenance manage, the same that are mentioned in descending order in accordance with the qualification percentage obtained through the hierarchical analysis process (HAP): maintenance organization (21%), control to the management (20%), planification and organization (18%), human resources of maintenance (17%), corrective maintenance (10%), inventory management for the maintenance winery (8%) and external recruitment of maintenance (6%). The auditing process has four stages: to plan, to do, to verify, and to act, which are the pillars of the continuous improvement. The evaluation process of the maintenance management was executed using the auditing plan and the obtained resources are presented in charts and in graphics. The audited maintenance management showed three nonconformities in the of professional formation sub-criteria, maintenance budget and criticality analysis based on the risk. Each finding of the auditing process is documented with its respective evidence and after to examine the auditing results, it was concluded that the audited maintenance management, it is found in a quasi-satisfied level for this reason it is recommended to realise a follow-up audit.
