Models for the formation of an optimal set of investment projects for the modernization of the production base of an industrial enterprise, taking into account the coordination of objects and implementation deadlines

this article examines the problem statement and mathematical model for selecting the optimal set of expansion and modernization projects for the primary process equipment in the primary production shops of a multi-product serial enterprise across groups of so-called "key" assets, the production capacity of which limits the volume of output. The criterion is the overall effectiveness of the projects accepted for implementation, assessed by the increase in production potential in groups of key fixed assets. The model's constraints, along with financial and resource constraints, include, in a formal mathematical expression, constraints defining the relationship between two or more projects in terms of implementation objects, timing, and funding volumes. The resulting problem is represented by a discrete nonlinear model that can be expanded by incorporating an additional option related to the selection of the optimal capital structure financing the projects selected for the optimal investment program.
