Hussam Hamrawi, Simon Coupland · DMU Open Research Archive (De Montfort University) · 2009
This paper examines type-2 fuzzy arithmetic using in- terval analysis. It relies heavily on alpha-cuts and alpha-planes. Fur- thermore, we discuss the use of quasi type-2 fuzzy sets proposed by Mendel and Liu and define quasi type-2 fuzzy numbers. Arithmetic operations of such numbers are defined and a worked example is pre-
