AHP-based group decision making using keypads

In this paper, we deal with the analytic hierarchy process (AHP)-based group decision making using keypads. It is a way of aggregating group judgements that allows a group to enhance the validity of the outcome by including the importance of people's knowledge, expertise and experience, to accept the disparate power of its members when eliciting their judgements, and to make group decision making more efficient, by reducing the redundancy in judgements and spending less time and money on reaching an agreement. In addition, we present the case study 'Ranking the means of state support for international projects'. The purpose of this paper is to provide a thorough insight into the use of the AHP-based group decision making using keypads, i.e. a multiple criteria decision-making methodology which provides an effective framework for guiding managers in solving problems based on the group decision making.
