The circular economy is interpreted as a stable economic system, which aims at eliminating the consequences and costs, as well as providing a constant cycle of necessary resources. That is why it is so important to conduct its assessment today. The object of the article is the state of the circulating economy of the leading countries of the world. The purpose of the article is to assess the possibilities and mechanisms of the circular economy in the context of the introduction of the European Union. The methodological basis is a system of mutually complementary general scientific and special methods of cognition. To assess the quality of the implementation of the circular economy, we have chosen the recycling method as the most relevant and easiest to use. The study examined the essence, progress, principles and main advantages of using the circular economy model in the context of implementing this model in 20 countries of the European Union, and the model for analysing the processing possibilities in the European Union as a basic tool for assessing the implementation of a circular economy are presented.

The main purpose of the study is the formation the methodological approach to assessing the options for transforming of the main business process in the context of ensuring security. The study is based on the assessment results of several of leading engineering enterprises. The methodology of estimation of efficiency of carrying out transformation of the basic business processes of the enterprises, based on the theory of fuzzy sets, is a convenient means of carrying out multicriteria evaluation, comparative analysis from the point of view of integrated criterion and obtaining orderly priority of business processes on their efficiency. The study of the process of transformation of a business process for the production and sale of product enterprises was conducted and a methodology for assessing its effectiveness based on the use of the mathematical apparatus of the theory of fuzzy sets was formed and allows us to formalize and evaluate the effectiveness of the implementation of each of the options for the business process. Methodology for assessing the effectiveness of the transformation of the main business processes at the enterprises can be used in enterprises of various profiles after the necessary analysis and optimization. The study conducted a comprehensive assessment of the effectiveness of the transformation of the main business processes at the enterprises using as example engineering enterprises in the context of ensuring security.

In recent years, the idea of green growth has been widely discussed not only by experts in environmental economics, but also in various political forums. Many countries use various tools and principles of green growth in their national policies and growth strategies. However, some countries fear that the transition to a green growth model may hamper their development. The article discusses the prerequisites for implementation, the basic principles of green growth into the system of public administration, and also provides a system for modelling ways to implement the principles of green growth using the IDEF0 (functional modeling methodology and a graphical description of the processes) methodology. This methodology allows to clearly see the ways and means of achieving this goal. Considering the importance of the economic component in all processes of monitoring, control and protection of air, water and soil from pollution processes, a system for modeling ways to implement the principles of green growth using the IDEF0 methodology has been formed today is especially relevant.

Today, the principles of a green economy are being updated and studied not only by experts in the field of environmental economics, but also in various political circles. A large number of countries use different instruments and principles of a green economy in their development policies and strategies. However, some countries fear this transformation because they believe that the transition to a green economy model may hinder their development. Thus, the formation of a clear methodology for the “green” economy is extremely relevant today. The main purpose of the study is to form ways to improve green economy and environmental protection in the context of governance. The article discusses the prerequisites for implementation, the basic principles of Green economy into the system of public administration, and also provides a system for modelling ways to implement the principles of Green economy using the IDEF0 methodology. This methodology allows to clearly seeing the ways and means of achieving this goal.

В статті наведено аргументи щодо необхідності розробки та впровадження відновлюваної моделі соціально-трудового розвитку під час розгортання нової світової кризи, що є важливим та нелегким викликом для України. Виявлені ризики та загрози, реальні та потенційні можливості для соціуму, зумовлені змінами технологічного, демографічного, глобалізаційного характеру та визначені зміни, які пов’язані з новими трендами у ресурсах, технологіях, продуктивності у контексті можливостей і обмежень соціально-трудової сфери українських підприємств.
