Using the example of the Ukrelektromash plant, the application of various types of real options is considered depending on the development of the project scenario for the production and sale of rotary hybrid engines. The conditions and criteria for the application of option mechanisms are defined, taking into account the impact of risks, which is reflected in the assessment of the probabilities of the development of one or another type of scenario. The effectiveness of using abandonment and switching real options to a related type of activity in the event of a pessimistic development of cash flow and options to expand and replicating experience real option in the event of an optimistic scenario has been proven. At the same time, the degree of effectiveness of the manager's actions is shown, depending on the results of the project's cash flows after the first year of implementation. It has been established that real options are able to generally increase the strategic value of international investment projects, creating conditions for the post-war reconstruction of Ukraine's industry and encouraging the cooperation of foreign investors. In this way, the use of real options enables the manager to take effective measures to manage risks and cash flows, improving the degree of attractiveness of investment projects, and thereby opening new opportunities for cooperation with foreign partners. The implementation of programs with the use of real options becomes necessary when the investor is wary of investing in the development of the country after the end of the war, and at the same time sees great potential for the development of various sectors of the economy. Reducing the degree of riskiness of projects with the help of real options contributes to the gradual restoration of industrial capacities, the acceleration of money circulation, and the improvement of trade and financial operations on international markets.
