Abstract:

The investment climate characterizes the object's attractiveness for a domestic or foreign investor. It is evaluated using various statistical analysis methods, but there has yet to be a universally accepted method of its evaluation now. Therefore, applying economic and mathematical modeling will allow for assessing the relationship between the economic development of regions and their investment climate. The purpose of this research is to apply economic and mathematical tools for the assessment and analysis of the investment climate of industrial parks of Ukraine within specific regions and i

However, the efficiency of its production largely depends on the quality of the ozonators’ electrical power sources. In this research, we developed and utilized mathematical models aimed at determining the main electrical parameters of various types of ozonators used in ozone production. The results of the study show possibilities for

With the continuous development of China's economy, the problem of environmental pollution is becoming more and more serious. The formulation and implementation of environmental protection policies have greatly promoted the development of resources and industries. At the same time, resource development and industrial development play an important role in the formulation of environmental protection policies, and the two influence each other and complement each other. Generally speaking, the better the environmental policy, the lower the level of pollution and the better the state of the environ
