  With the ever increasing complexity of Industry 4.0 systems, plant energy
management systems developed to improve energy sustainability become equally
complex. Based on a Model-Based Systems Engineering analysis, this paper aims
to provide a general approach to perform holistic development of an autonomous
energy management system for manufacturing industries. This Energy Management
System (EMS) will be capable of continuously improving its ability to assess,
predict, and act, in order to improve by monitoring and controlling the energy
sustainability of manufacturing systems. The approach was implemented with the
System Modeling Language (SysML).
