Application of satisfactory degree to interval-valued intuitionistic fuzzy Author(s): lidengfeng ,Yugaofeng J. Ponte - May 2016 - Volume 72 - Issue 5 The process of paper has not been completed.
Abstract: The aim of this paper is to propose a satisfactory degree by using
a nonlinear programming method for solving multi-attribute
decision making (MADM) problems, in which rating of alternatives
on attributes is expressed via interval-valued intuitionistic
fuzzy (IVIF) sets and preference information on attributes is
complete. Concretely, a nonlinear programming model is firstly
explored to determine the satisfactory degree which is the ratio
of the square of the weight Eucildean distance between an
alternative and the IVIF negative ideal solution (IVIFNIS) to the
sum of the square of the weight Eucildean distance between the
IVIF negative ideal solution and the IVIF positive ideal solution
(IVIFPIS). Another nonlinear programming model is also developed
to obtain satisfactory intuitionistic fuzzy sets, and then the
general satisfactory degrees of the satisfactory intuitionistic
fuzzy sets are used to generate the ranking order of the
alternatives. Finally, a real example of the investment company
selection problem is employed to verify the applicability of the
proposed approach and to illustrate its practicality and
effectiveness.
