Opinion surveys are widely admitted as a valuable source of information which becomes complementary to the information extracted from data by machine learning techniques. This paper focuses on a challenging and still open problem which is related to how to handle properly the inherent uncertainty of human perceptions. Namely, we propose new ways to interpret and analyze fuzzy data coming out fr...

As key players in innovation and entrepreneurial ecosystems, Higher Education Institutions (HEI) assume a position as catalysts creating disseminating knowledge with repercussions the societal, economic, political environments. In this scenario, HEI are facing need to balance performance of their traditional missions—teaching research—with pursuit performance. This brings awareness pay particul...

Comparative analysis of two ideologically distinct approaches in the theory of fuzzy di"erential equations is given. Domains of applications, advantages and shortcomings of those approaches are described. New de2nitions of solutions to fuzzy di"erential equations are proposed. c © 2002 Elsevier Science B.V.

One apparent limitation of the truth table approach is that it is designed for causal conditions that are simple presence/absence dichotomies (i.e., Boolean or "crisp" sets-chapter 3) or multichotomies (MVQCA--chapter 4). Many of the causal conditions that interest social scientists, however, vary by level or degree. For example, while it is clear that some countries are democracies and some ar...

Despite this growing adoption of enterprise architecture (EA), there has been little research that provides compelling empirical evidence of the EA impact on organizational performance. We argue that the lack of strong empirical evidence is due to the complexity of EA configurations and the limitations of the traditional correlation-based methods for uncovering the complex relationships. This r...

This paper applies different methods of map comparison to quantify the characteristics of three different land change models. The land change models used for simulation are termed as ―Stochastic Markov (St_Markov)‖, ―Cellular Automata Markov (CA_Markov)‖ and ―Multi Layer Perceptron Markov (MLP_Markov)‖ models. Various model validation techniques such as per category method, kappa statistics, co...

As one of the promising renewable energy resources, solar-wind energy has increasingly become a regional engine in leading the economy and raising competitiveness. Selecting a solar-wind power station location can contribute to efficient utilization of resource and instruct long-term development of socio-economy. Since the selection procedure consists of several location alternatives and many i...

In this paper, the effects of uncertainty on multiple-objective linear programming models are studied using the concepts of fuzzy set theory. The proposed interactive decision support system is based on the interactive exploration of the weight space. The comparative analysis of indifference regions on the various weight spaces (which vary according to intervals of values of the satisfaction de...

In order to involve user knowledge in determining equality of sets, which may not be equal in the mathematical sense, three types of approximate (rough) equalities were introduced by Novotny and Pawlak ([8, 9, 10]). These notions were generalized by Tripathy, Mitra and Ojha ([13]), who introduced the concepts of approximate (rough) equivalences of sets. Rough equivalences capture equality of se...

Many measures of similarity among fuzzy sets have been proposed in the literature, and some have been incorporated into linguistic approximation procedures. The motivations behind these measures are both geometric and set-theoretic. We briefly review 19 such measures and compare their performance in a behavioral experiment. For crudely categorizing pairs o f fuzzy concepts as either "'similar" ...
