The issue of modelling decision-making in the field of green production in a post-industrial society determines the relevance of the study. The main goal of the study is to develop a decision-making model that can help green industry organizations identify optimal strategies and actions to reduce environmental impacts, ensure sustainable efficiency, and promote development. The methodology used in the study involved a theoretical analysis, synthesis, and mathematical modelling methods. As a result, an innovative mathematical model was developed and proposed, which allows predicting the influence of various factors when choosing the optimal production strategy. The results show that the application of the developed model allows Ukrainian enterprises in the field of green production to determine optimal strategies aimed at reducing the environmental impact of production processes on the environment. It helps to ensure sustainable production efficiency, contributing to the economic sustainability of enterprises and the global economy.
