An information decision support system towards the formulation of a modern energy companies’ environment

The development of the renewable energy sources (RES) and the energy efficiency (EE) is related to the enhancement of the energy companies’ (energy producers by RES and energy services companies—ESCOs) operational environment. The aim of this paper is to present an information decision support system, which consists of an expert subsystem, as well as a multi criteria decision making (MCDM) subsystem. The system supports the state toward the formulation of a modern environment, since it incorporates the “new parameters” of the energy market, namely the liberalization and the climate change. The system was successfully applied in the 13 accession member states of the EU.
