EN This paper describes an approach to multi-criteria evaluation of project variants based on the fuzzy set theory. The multi-criteria evaluation based on the criteria proposed by experts or decision-makers in the planning phase, during which it is critical to document the tasks to be completed in a project schedule. Fuzzy sets theory transforms criterion indicators into variants fuzzy partial evaluations by means of transformation functions. The method facilitates comparison of different values by transformation to the fuzzy numbers from the range of ⟨0, 1⟩.The presented approach offers support for the decision makers in making various kinds of decisions, in all situations when we may determine an evaluation criteria set. Moreover, it takes into consideration versatility of criteria, their hierarchy and experts’ uncertainty; at the same time it is efficient and quite simple to be implemented in real decision problems.
