Extended grey numbers and their operations

— Combining both intervals and discrete sets of numbers, this paper presents a definition for an extended grey number model representing both continuous and discrete grey numbers. Based on the new definition, the operation properties and degree of greyness are investigated and a new formula for arithmetic operations of grey numbers is derived.
