Information and Communication Technologies The use of automation and control systems, process design and optimization, software modelling, and computer aided tools. ICTs reduce the complexity of industrial processes by: (a) Obtaining real time information about energy measurements (b) Facilitating the decision making for investments in energy efficient technologies (c) generating positive environmental results and financial savings for the companies.

Sub-categories in the ICTs ICT include a varying number of continuously keep evolving resources and technologies. The main sub-categories in the ICT field include: (i) Process automation (ii) ICT-enabled production control (iii) Monitoring and decision making (iv) Integration of processes and information flows
