Effective strategy for implementing state financial assistance in the use of alternative energy technologies for critical infrastructure enterprises under elevated national security threats

The purpose of this article is to present a contemporary methodological approach to developing an effective strategy for implementing state financial assistance in the use of alternative energy technologies for critical infrastructure enterprises. The object of the study is critical infrastructure enterprises. The scientific task involves modeling that would allow the formation of an effective strategy for implementing state financial assistance in the use of alternative energy technologies for critical infrastructure enterprises. The research methodology includes the application of the IDEF0 method to construct a model for implementing state financial assistance in the use of alternative energy technologies for critical infrastructure enterprises. As a result of the conducted research, a decomposition of the context diagram was proposed to improve the efficiency of implementing state financial assistance in the use of alternative energy technologies for critical infrastructure enterprises. The study is limited by considering only critical infrastructure enterprises in Ukraine. Prospects for further research will include considering enterprises from other countries, particularly Poland.
