osting by E Abstract Direct adaptive fuzzy controller is a class of adaptive fuzzy controllers which use fuzzy logic system (FLS) as controller. Interval type-2 fuzzy sets are able to model and minimize the numerical and linguistic uncertainties associated with the inputs and outputs of fuzzy logic controller (FLC). In this paper, a direct adaptive interval type-2 FLC is proposed for controllin...

The objective of this paper is to present an approach that utilizes an interval type-2 fuzzy decision making system (IT2FDMS) to quantify the Project Management Efficiency (PME). The algorithm developed in this paper is based upon interval type-2 fuzzy logic, giving it the ability to solve complex problems plagued with uncertainty and vagueness. A interval type-2 fuzzy decision making system is...

The estimation of the fuzzy membership function parameters for interval type 2 logic system (IT2-FLS) is a challenging task in presence uncertainty and imprecision. Grasshopper optimization algorithm (GOA) fresh population based meta-heuristic that mimics swarming behavior grasshoppers nature, which has good convergence ability towards optima. main objective this paper to apply GOA estimate opt...
