Data-driven sustainability evaluation of machining system: a case study

Improving resource efficiency and reducing waste discharge are the inevitable trends of development sustainable machining system. Therefore, a data-driven sustainability evaluation method system is proposed. The input (energy, materials, equipment, R&D, services) output (wastes products) data collected. These dimensional processed by emergy. emergy flow calculation model process established for modeling, index constructed analysis. Finally, an engine base taken as case study innovative practice, targeted optimization adopted based on its practice. feasibility effectiveness verified. This provides theoretical methodological support promoting manufacturing industry.
