Analysis tools should help identify problem situations ("bottlenecks") in ensuring the quality of life of population and to form a "tree" of management goals for the development of territory and improvement of life of population. The solution of these problems is possible by creating a human-machine platform for scenario analysis of the development of territories for numerous aspects of management. The decision-making process based on the representation, calculation and interpretation of current observed and predicted parameters is effective for both operational management and strategic planning. The information and analytical system under development is intended to become a convenient and powerful tool for analyzing the level of development of a region, scenario analysis, planning support and making high-quality management decisions.
