Abstract
The Earned Value Method is in the first place a tool of project cost control. In consecutive control moments the attempt is made to reestimate the total cost of the whole project, individual activities or groups of activities, taking into account the information available in the control moment. Because the method is future oriented, the fuzzy approach is here more than appropriate. There exist several fuzzy versions of the method. None of them, however, allows to take into account important qualitative factors (inducing emotions, rumours about changes in the project, negotiations going on etc.). This paper proposes such a fuzzy version of the method which allows considering such factors. Additionally, the proposed method focuses on individual activities (and not on the whole project, like the existing methods). The most critical activities in terms of cost should be selected for analysis.
