Methodology for the Economic Assessment of the Effectiveness of Digital Transformation of Infrastructure Facilities in the Far North

The article develops a methodology for the economic assessment of the effectiveness of the Far North infrastructure facilities digital transformation. The research problem is that the digital transformation of northern infrastructure is often described through the implementation of platforms, sensors, and monitoring systems, whereas regional and sectoral economics requires the assessment of total cost reduction, lower downtime, prevented damage, capacity growth, and return on investment. Domestic and foreign studies are used to systematize the types of economic effects generated by the digital transformation of infrastructure facilities. The proposed calculation framework includes annual net cash effect, total cost of ownership (TCO), net present value (NPV), internal rate of return (IRR), profitability index (PI), and discounted payback period (DPP). The obtained results make it possible to consider the northern infrastructure digital transformation as an economic tool for reducing the infrastructure costs, rather than only as a means of improving the technical reliability.
