GRAPE: A Grid for Ranking and Analysis of Priority Environmental indicators in maintenance activities

The increasing environmental impact of industrial operations has emphasized the need for sustainable practices in maintenance activities. This paper introduces GRAPE (Grid for Ranking and Analysis of Priority Environmental indicators), a systematic evaluation framework designed to identify, classify, and prioritize environmental indicators associated with maintenance processes. By integrating environmental, operational, and transportation-related impacts, the GRAPE framework assesses indicators using three key criteria: importance, measurability, and urgency. The result is a quantifiable Environmental Impact Priority Level (EIPL), facilitating targeted decision-making and preventive strategies. A case study on distributed maintenance demonstrates the applicability of GRAPE, highlighting high-priority indicators and suggesting optimization actions such as route planning, stock sizing, and water treatment. The GRAPE grid offers a practical tool for aligning maintenance strategies with environmental sustainability goals..
