This paper presents a novel multiple criteria decision making (MCDM) methodology for assessing and prioritizing medical tourism destinations in uncertain environment. A systematic evaluation and assessment method is proposed by incorporating Analytic Hierarchy Process (AHP) and Multi-Attribute Border Approximation area Comparison (MABAC) methods in rough number.

In the forthcoming heterogeneous wireless environment, the mobility management of users roaming between different wireless access technologies is a challenging and important technical issue. New mobile devices such as netbooks, smartphones and tablets allow users to perform vertical handoffs among different wireless networks. The multiple attribute decision making (MADM) methods are suitable to...

This paper presents a model based on a novel compromised solution method to solve the multiobjective large-scale nonlinear programming (MOLSNLP) problems with block angular structure. In this method, an aggregating function that is developed from TOPSIS and VIKOR is proposed based on the particular measure of ‘‘closeness” to the ‘‘ideal” solution. The decomposition algorithm is utilized to redu...
