AN OPTIMIZATION MODEL FOR ASSESSING THE ECONOMIC EFFICIENCY OF INFORMATION TECHNOLOGY PROJECTS

of net present value, internal rate of return and the payback period of an investment project. Some features of information technology projects are analyzed, in particular, the feature associated with the impossibility of considering project income as a systematic sale of IT products (IT goods and/or IT services). The model proposed by the author considers the characteristics of products, fixed assets and the market environment of projects, the efficiency criterion in the form of maximizing the value added to investments, investment, production and financial restrictions on the flows circulating in the model. The construction of the model is carried out in accordance with the principle of model and information technology balance, which consists in the requirement that the complexity of the model must corresponds to the capabilities of automated software systems to carry out its analysis in real conditions of a large number of types of IT products. To support the adoption of investment decisions, an optimization approach is fundamentally used, which makes it possible to identify the investment potential (maximum investment opportunities) as the value of the information technology project value added to the investment. In this regard, the paper builds and discusses a model in the form of a multi-parameter linear optimal control problem, which has well-developed methods of analysis and corresponds to the above balance principle.
