Evaluation of Interoperability between Automation Systems using Multi-criteria Methods

Abstract The diagnosis of automation systems in an existing production system through the analysis of the interoperability level between its components represents the first step in its evaluation for improving it towards alignment with Industry 4.0. The analysis of the level of interoperability finds in the multi-criteria decision making methods an auxiliary tool to evaluate and classify the solution. This work uses the AHP method for this evaluation, drawing criteria from the literature and expert experience. The application of the method is illustrated, showing that it can direct investment decisions.
