Abstract

DONA, Jesús M.; GIL, Antonio M.; LA RED, David L.  and  PELAEZ, José I.. A system based on the concept of linguistic majority for the companies valuation. EconoQuantum [online]. 2011, vol.8, n.1-2, pp.121-142. ISSN 2007-9869.

Nowadays, it is common the use of qualitative information expressed by experts to solve the problems of economic-financial assessment in uncertainty environments. Two are the difficulties presented in this type of problems; the first one focuses on the information given by the expert, which can be represented in different domains of expression, and the second one is relative to the obtained final solution, which must be representative for most of the experts involved in the process. To solve the first problem, the information representation has been proposed by means of the fuzzy model of linguistic 2-tuples, which allows treating as an homogeneous form the information expressed by the experts in different domains. To solve the second problem, in this work it is proposed to make use of the concept of majority through the OWA operators.

Keywords : Companies valuation; linguistic 2-tuples; OWA Operators.
