The aim of the present paper concerns a Hybrid Multi-Criteria Decision Model (HMCDM) to evaluate Maintenance Strategy. In order to improve production performance, in particular system availability and to reduce cost organization, in particular maintenance cost an integrated MCDM approach is proposed. The aim of the proposed method is to suggest the best maintenance solution for industrial systems. The new hybrid model is able to overcame the shortcomings of literature methods, matching Analytic Hierarchy Process (AHP) with Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) for the evaluation of maintenance policy. The proposed model has been applied in a real case study in a water bottling company. Different maintenance alternatives were considered and different criteria and sub-criteria were evaluated using Reliability, Availability, Maintainability, Safety (RAMS) and production parameters. The outputs suggested the best maintenance solution for all machines in the analyzed company. The results highlight a Maintenance Cost reduction and a System Availability increase of analyzed water bottling company.

Abstract
The aim of the present paper concerns a Hybrid Multi-Criteria Decision Model (HMCDM) to evaluate Maintenance Strategy. In order to improve production performance, in particular system availability and to reduce cost organization, in particular maintenance cost an integrated MCDM approach is proposed. The aim of the proposed method is to suggest the best maintenance solution for industrial systems. The new hybrid model is able to overcame the shortcomings of literature methods, matching Analytic Hierarchy Process (AHP) with Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) for the evaluation of maintenance policy. The proposed model has been applied in a real case study in a water bottling company. Different maintenance alternatives were considered and different criteria and sub-criteria were evaluated using Reliability, Availability, Maintainability, Safety (RAMS) and production parameters. The outputs suggested the best maintenance solution for all machines in the analyzed company. The results highlight a Maintenance Cost reduction and a System Availability increase of analyzed water bottling company.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
