An approach to the prioritization of sustainable maintenance drivers in the TBL framework

The current sustainable production model is supported by the Triple Bottom Line (TBL) concept and its three dimensions: economic, environmental, and social. This paper aims to propose an approach to identify and prioritize the attributes of the TBL dimensions, extracted from the Global Reporting Initiatives guidelines (GRI). This can help enterprises to target a desirable Overall Equipment Effectiveness (OEE). This is a well-established industrial indicator concerning maintenance actions. At first, a literature review is conducted in order to define the attributes to prioritize. Then, the Analytical Hierarchical Process (AHP) is used in order to rank the attributes of the TBL, as well as to support a sensitivity analysis for checking the enhancement of attributes, according to OEE world-class level references. As a result, the ranked attributes contribute for a maintenance performance evaluation and improvement of its operational efficiency in a sustainable approach.
