Abstract
The article describes the results of the research of structuring and evaluation of the factors affecting the efficiency of decision making regarding the use of water bodies. The authors define seven aggregated thematic groups of factors: information, technology, environmental, economic, legal, institutional and social. For estimation of demonstration and qualitative factors, conventional 5-point scales have been developed. In order to determine the significance of each factor, three categories of the subjects involved in decision making have been identified: subjects that justify and influence decision making; subjects that make final decisions; subjects that experience the consequences of decision making. According to the survey results of the representatives of the first two categories, the ranking of expert evaluations was carried out and the significance of the factors was determined. It was proved that information factors are the most significant, among which geospatial information is of particular importance. An algorithm based on the Cobb-Douglas logarithmic function is proposed for integral estimation of the efficiency of decision making regarding the use of water bodies. This approach allows to evaluate the efficiency of the decisions implemented and to forecast the results of the future ones.
