Many real-world decision problems involve conflicting systems of criteria, uncertainty and imprecise information. Some also involve a group of decision makers (DMs) where a reduction of different individual preferences on a given set to a single collective preference is required. Multi-criteria...

The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is a well-known Multi-Attribute Decision Making (MADM) method that is used to identify the most attractive alternative solution among a finite set of alternatives based on the simultaneous minimization of the distance...

The increasing intensity of global competition and the rapid advances in information technology (IT) have led organizations to search for more efficient and effective ways to manage their business. With the rapid growth of IT and global complexity, selecting information system projects that...

In this study, we propose a three-stage weighted sum method for identifying the group ranks of alternatives. In the first stage, a rank matrix, similar to the cross-efficiency matrix, is obtained by computing the individual rank position of each alternative based on importance weights. In the...

This paper presents a group decision support system (CDSS) which integrates the analytic hierarchy process (AHP) into a Delphi framework. The AHP-Delphi GDSS is applicable to a wide range of complex, multi-criteria decisions which require judgements about qualitative characteristics from a group...
