As intuitionistic trapezoidal fuzzy number can reveal the degree of an attribute satisfy or dissatisfy a trapezoidal fuzzy number rather than a certain fuzzy concept, it is interesting to introduce it to resolve multi-criteria decision making problems. This paper reviews some existed intuitionistic trapezoidal aggregation operators and presents a new arithmetic aggregation operator, i.e. induced intuitionistic...
Information systems project selection is a multi-criteria decision-making (MCDM) problem. This work develops a fuzzy approach based on the technique for order performance by similarity to ideal solution (TOPSIS), to choose optimal information system in a fuzzy environment where the data are often incomplete or not so deterministic. In this paper, the importance weight of each criterion and the rating...
The demand for outsourcing in the information systems (IS) field has become a part of basic corporate strategy and has experienced a considerable growth in recent years. The process of IS outsourcing is always involved in a variety of situations and decision problems under fuzzy environment.

In decision making problems with multiple experts as group decision making (GDM), each expert expresses his/her preferences or judgments depending on his/her own knowledge or experiences. A more realistic approach may be to use linguistic assessments instead of numerical values. Therefore, decision-makerspsila opinions are described by linguistic variables which can be expressed in different types...
