Energy planning problems with interval-valued 2-tuple linguistic information

In this paper, we address to the concern as to which alternative is most suitable for energy production in a new power plant set up in India. We model this problem as a multi-criteria group decision making problem where the criteria values are described in terms of interval-valued 2-tuple linguistic variables. We propose to solve this model by extending the PROMETHEE II method to interval-valued 2-tuple linguistic variables where the criteria weights in the PROMETHEE II method are supplied using the entropy measure. A small example is presented to illustrate the practicality and usefulness of the proposed method.
