Optimal Investment of Socially Significant Events in the Region on the Basis of Public-Private Partnership

The subject of the study is the development of the Arctic and the reindustrialization of the old — developed regions of Russia, which increase the transport and environmental burden on the population. To reduce it, it is necessary to harmonize the interaction of economic entities and the population through the implementation of socially oriented measures through investments in the framework of public-private partnership (PPP), in which small and medium-sized businesses participate. The purpose of the work is to develop procedures, models and algorithms for planning socially significant events, taking into account PPP.

The result of the work was the creation of a procedure for planning socially significant events, including the implementation of an iterative process to ensure that the allocated investments correspond to the period of implementation of a set of established activities; following an economic and mathematical model for forming a schedule of activities, taking into account limited investments and a model for determining the optimal equity participation of each of the co-investors in the implementation of activities. To create a schedule for the implementation of events, a step-by-step algorithm for their sequential assignment is given, which has been successfully applied to solving problems of large dimension. In order to find the optimal equity participation of coinvestors in ensuring investments, an algorithm is proposed that provides a solution to this problem with a priori specified accuracy.

Conclusions are drawn that the proposed procedure for planning socially significant events, the models formed and the algorithms given in the article can be applied in a complex or locally with an unlimited number of co-investors and ongoing events.
