Laboriousness Estimation Approach of Research, Scientific and Development Works in Power Engineering with Fuzzy Expert Judgments

Background: The expert estimation problem of research, scientific and development works laboriousness in power engineering in consideration with its innovation components is actual for estimating costs of research projects. Materials and methods: Expert judgments are expressed by linguistic variables. The mathematical apparatus of fuzzy set theory is used for this processing. Results: Two methods of research and development project costs estimation in power engineering are described. The possibility of fuzzy logic application of implementation of expert approach to the problem is proved. The method of fuzzy expert judgments formation is proposed for estimation of complexity differences between a project under consideration and a benchmark project. Conclusions: The proposed method allows to estimate costs of a research and development project in power engineering even in case of significant complexity differences compared to existing benchmarks.
