Selection of Public Capital Projects using IF-Sets

摘要

The paper presents basic notions of intuitionistic fuzzy sets (IF-sets) introduced by K.T. Atanassov. Further, we define a set of criteria for the selection of public capital projects. The selection process is realized by two approaches. Sanchez's approach is based on the max-min-max composition of IF-relations, while Li's approach consists in the optimization of IF-relations. The results show that IF-sets provide a good description of public capital projects by means of membership functions and non-membership functions since they enable processing of a great deal of uncertainty.
