Determining and Applying Productive, Environmental and Economical Indicators and Indexes to a Cyber Physical System for Greening Process of Supply Chain

Sustainability is taking on increasing value in the industrial world. This article aims to develop and implement in a cyber-physical system two new KPIs capable of transferring the current concept of Supply Chain (SC) to a Green Supply Chain (GSC), which no longer addresses only the productive and economic issues of traditional SC, but also addresses issues of sustainability, relying on industry 4.0 to achieve this goal. Each KPI has a different function within this process. The first one allows selecting the most adequate scenario to be implemented in the SC from all those proposed, attending to these three issues at the same time (productive, economic and environmental). The second allows the monitoring, at the same time, of the machine tool in these three dimensions, so that, it is possible to analyze throughout the production period of the machine its productive, economic and environmental evolution.
