Systematic approaches to making decisions in the public sector are becoming
very common. Most often, these approaches concern expert decision models. The
expansion of the idea of the development of e-participation and e-democracy
was influenced by the development of technology. All stakeholders are
supposed to participate in decision making, so this brings a new feature to
the decision-making process, in which amateurs and non-specialists are
participating decision making instead of experts. To be able to understand
the needs and wishes of stakeholders, it is not enough to vote for
alternatives - it is important to participate in solution-finding and to
express opinions about the important elements of these matters. The solution
presented in this paper concerns fuzzy decision-making framework. This
framework combines the advantages of the introduction of the decision-making
problem in a tree structure and the possibilities offered by the flexibility
of the fuzzy approach. The possibilities of implementation of the framework
in practice are introduced by case studies of investment projects appraisal
in a community and assessment of efficiency and effectiveness of public
institutions.
