The paper presents an alternative and original method for establishing the present worth and feasibility of a capital investment where the underlying parameters of interest/discount rate, cash flows and investment lifespan are uncertain. The method, based on Markov chains, complements existing and useful practices such as sensitivity analysis, Monte Carlo simulation, Hillier style probabilistic...

Fuzzy Protégé is a semi-automatic collaborative tool for the construction of fuzzy ontology models, built as a Protégé 3.3.1 tab plug-in. Fuzzy Protégé is an extension of the well known ontology editor Protégé for which we have defined new meta-classes to allow the definition of parameterized membership functions. Fuzzy Protégé also gives support to instantiate fuzzy concepts and roles and allo...

In this paper, the Kapur cross-entropy minimization model for portfolio selection problem is discussed under fuzzy environment, which minimizes the divergence of the fuzzy investment return from a priori one. First, three mathematical models are proposed by defining divergence as cross-entropy, average return as expected value and risk as variance, semivariance and chance of bad outcome, respec...

On the basis of the combination of single-valued neutrosophic sets and hesitant fuzzy sets, this article proposes a single-valued neutrosophic hesitant fuzzy set (SVNHFS) as a further generalization of the concepts of fuzzy set, intuitionistic fuzzy set, single-valued neutrosophic set, hesitant fuzzy set, and dual hesitant fuzzy set. Then, we introduce the basic operational relations and cosine...

The theory of intuitionistic fuzzy set (IFS) is well suitable to deal with vagueness and hesitancy. In this study, we propose a new fuzzy TOPSIS decision making model using entropy weight for dealing with multiple criteria decision making (MCDM) problems under intuitionistic fuzzy environment. This model allows measuring the degree of satisfiability and the degree of non-satisfiability, respect...
