Abstract
The heavy equipment industry must balance operational efficiency with sustainability. Using the PRISMA approach, this study systematically reviews key operational performance indicators (KPIs) for sustainable lean supply chain management. Analyzing over 220 papers, it identifies crucial KPIs, including cost efficiency, resource optimization, waste reduction, carbon emissions, and product quality. Integrating these indicators into supply chain processes enhances both performance and sustainability. The research provides a comprehensive KPI framework, aligning lean principles with environmental and economic goals, and offering valuable insights for optimizing supply chain management in the heavy equipment industry.
