applied in many fields. Current developing in granular computing is more a theoretical perspective than a set of computational methods or processes. This paper attempts to narrow the gap between the theoretical concept and real- world application of granular computing. Multitasking is a method with multiple tasks or processes share with common resources and apply the given input data. This paper introduces some good feature in multitasking that can accomplish the goal of granular computing.
