International experience demonstrates both the effectiveness and difficulties of using the mechanism of a public–private partnership (PPP) in solving socially significant problems of investment development of an innovative economy. The lack of tools to make an informed choice of the best PPP model in terms of the risks diversification is one of the significant problems of the predictive and analytical support of the relationship between business and government structures. The purpose of the study is to create and empirically test a multi-criteria modeling toolkit for the choice of the public–private partnership mechanism in relation to managing territorial sustainable development projects. Such problems as a structural representation of PPP risk factors and development of principles for their diversification, development of the algorithm and criteria for multi-criteria evaluation, testing of a multi-criteria model needed to be solved to achieve the research goal. The innovativeness of the author’s approach consists in substantiating the algorithm of the multi-criteria modeling for the choice of the public–private partnership mechanism in relation to managing sustainable development projects of the territory. Criteria for alternative PPP models evaluating have been developed. Based on the results of testing, the advantages and disadvantages of applying the algorithm of the multi-criteria modeling in sustainable development management are identified, the directions for the model using in regional management are disclosed.

This paper synthesizes two areas of research: control models in networks and sustainable development of active systems. The concept of an active network (an active system with a network structure) is proposed and formalized. Two common classes, hierarchical and non-hierarchical active networks, are identified and studied; some illustrative examples are given. The sustainable management problem of active networks is stated, and approaches to its solution are described. A model example of opinion control in an active network with sustainable development requirements is numerically simulated. For this purpose, the author’s method of qualitatively representative scenarios is used.
