Semko I. Models and methods of portfolios projects risk management in the energy industry

Object of investigation consists in analysing processes of controlling risks of project portfolios in the energy branch. Methods of investigating are as follows: system analysis, method of experts' estimates and probability theory, method of critical path, Monte Carlo method, synergetic approach. Practical significance of results of this investigation is as follows: scientific and practical instruments applied allow researchers to manage projects portfolios in the energy branch effectively. Scientific novelty of the investigation consists in theoretical and practical substantiation of basic scientific principles referred to control over risks of projects portfolios, namely: elaboration of models and methods of anti-risk planning of projects portfolios in the energy power. For the first time mathematical model of scenarios of implementing a project portfolio in the energy power was constructed; method of the anti-risk planning of projects portfolio was worked out. Mathematical model of synergetic effect of the project portfolio in the energy branch was perfected, as well as method of the experts' estimate of risks of projects portfolios in the power branch. Classifications of projects portfolios and their risks have obtained further development.
