Worldwide Investing in Real Estate Using Interval-Valued Intuitionistic Fuzzy Sets

Abstract

Global real estate investments have been one of the popular investment areas since developments in transportation vehicles among countries, significant reduction in travelling costs, and suitable legal arrangements for purchasing real estates in a foreign country have made it attractive. This investment decision is composed of three stages: Selection of a country, selection of a city, and selection of a district for a real estate. Since the selection process includes uncertain and vague evaluations under multiple criteria, a fuzzy multicriteria evaluation method is needed. In this paper we use interval-valued intuitionistic fuzzy sets to model this multicriteria and multiexpert problem.
