PROLOGUE TO THE SPECIAL ISSUE: APPLICATIONS OF APPLIED MATHEMATICS IN REAL WORLD PROBLEMS

Abstract

The challenge of real world problems poses the needed of developing new theoretic models , applying some well-
known methods as well a getting together existing softwares. This issue is constituted by a set of papers where the
authors describe the complexity of the problems to be solved and justify the methods used for deriving useful
recommendations to the decision makers. The complexity of real-world phenomena has motivated the development of theories, where the experts may introduce their criteria. This facts are modeled not only using popular quantitative models of statistics but also working within Fuzzy-sets, Rough-sets or Neutrosophic work-frames. The papers in this issue are good examples of
the creativity of the authors in modeling and of their abilities for deriving practical advises to the clients.
This issue provides presentations and the discussions have a clear nexus with nowadays knowledge and gives an
invaluable insight, transcending mere academic work. At its core this issue is an interdisciplinary platform where
researchers and practitioners unveil innovations, identifying new trends and challenges, motivated by the
complexity of the phenomena ubicated in the boundaries of different sciences. The contents may be classified in two groups. A first one concerned with social phenomena in Latin America countries and a second one clearly related with important economic problems present in management of accounting, environment and business in Middle East
