In modern conditions, a very important issue to ensure sustainable development is the constant implementation of innovation activity. Taking into account the high cost of energy carriers, the implementation of innovative energy saving activity is a very important issue. In this paper, the authors have simulated the process of intellectual support for management decisions to determine the sources of funding for innovative energy saving activity. The proposed mathematical model allows to use the concentrated experience of experts for intellectual support of decision-making on the estimation of efficiency of financial maintenance of innovation activity. The received results show that the evaluation of priority strategic directions for machine-building enterprises in terms of efficiency of financial support of innovation activity will determine a hierarchical structured set of innovation strategies for each enterprise, taking into consideration the available financial support and external and internal environment of the enterprise.
