@article{Dubrovin_Yuskiv_2019, title={THE STRUCTURE OF INFORMATION TECHNOLOGY FOR MANAGING PORTFOLIOS OF ENERGY SAVING PROJECTS AT METALLURGICAL ENTERPRISES}, volume={1}, url={http://ee.zntu.edu.ua/article/view/198839}, DOI={10.15588/1607-6761-2019-4-4}, abstractNote={<p><strong><em>Purpose.</em></strong><em> In the implementation of investment projects, the process of industrial production, associated with the choice of the optimal supplier, customer, business partner; determining the best quality of products, minimizing the cost of purchasing and delivering material resources, etc.. This article analyzes the information technology of a software product to automate the decision support process in the financial investment activity of a metallurgical enterprise..</em></p><p><strong><em>Methodology.</em></strong><strong><em> </em></strong><em>To solve the optimization problems, the following methods were applied: methods of studying the functions of classical analysis; indefinite Lagrange multipliers; variational calculus; dynamic programming; maximum principle; linear programming; nonlinear programming.. </em></p><p><strong><em>Findings</em></strong><strong><em> </em></strong><em>The designed system, helping to make the most effective, comprehensive solution, can reduce the intellectual burden on the decision maker, minimize the number of routine operations and complex mathematical and economic calculations and, as a consequence, significantly reduce the time for decision. The advantage of the considered software product is that it is able to solve simultaneously two urgent tasks for today - to form the optimal portfolio of securities and to choose the optimal supplier of resources. Thus, it is convenient for metallurgical enterprises and will reduce the cost of purchasing software.</em></p><p><strong><em>Originality</em></strong><strong><em>.</em></strong><em> This software product has no analogues at the moment, it is able to solve two current problems for today simultaneously - to form an optimal portfolio of securities, and to choose the optimal supplier, which will reduce the cost of purchasing materials and use these funds for the implementation of energy conservation projects at metallurgical enterprises</em></p><p><strong><em>Practical value.</em></strong><em> The calculation method offered by the choice of the optimal supplier is universal and acceptable for the evaluation of enterprises in terms of different characteristics: the proposed methodology is based on a comprehensive, multidimensional approach to the evaluation of such complex phenomenon as the financial and economic activity of the enterprise;</em> <em>a flexible algorithm is used to obtain the valuation of enterprises, which realizes the possibilities of a mathematical model of comparatively-complex evaluation of the enterprise activity; the algorithm of calculations allows to move away from formation of conditional reference enterprise; the calculation is based on determining the interval of variation of features; the technique is based on bringing the numerical parameters to a single equivalent, which in this case is the approximation coefficient to the optimal value of the trait. </em></p>}, number={4}, journal={Electrical Engineering and Power Engineering}, author={Dubrovin, V.
