Innovative propensity with a fuzzy multicriteria approach: Analysis of the Spanish industrial sector with data mining techniques

The purpose of this paper is to define an innovative propensity index (IPI) which considers these variables and allows the identification of those companies which have a higher propensity to implement different types of innovativeness.
