Economic-mathematical and logical-heuristic decision-making models: neosystemic synthesis

The article discusses approaches to assessing the systemic efficiency of large-scale institutional and investment projects with a high degree of uncertainty in their parameters. A hybrid assessment model is proposed, which includes a network model of a complex of operations that reflects the investment and construction process of creating a public property unit. The network model is formalized in two versions - as a deterministic network model and as a cyclic alternative one, which allows taking into account the probabilistic nature of the construction technology and find the best options for allocating resources for work, taking into account transaction costs.
