Fuzzy parameterized intuitionistic fuzzy soft multiset theory and decision-making

Abstract

In this paper, we have presented the idea of fuzzy parameterized intuitionistic fuzzy soft multiset (briefly, FPIFSM-set) and its basic properties are to be studied. Also, we define AND−t-norms, OR−t-norm, AND−t-conorm and OR−t-conorm products on FPIFSM-sets and using these products we introduce an adjustable approach to FPIFSM-set based decision-making, for solving decision-making in an uncertain situation. The feasibility of our proposed FPIFSMset based decision-making procedure in practical application is shown by some numerical models.
