Intuitionistic Fuzzy Set Theory with Fair Share CPU Scheduler

Abstract

CPU Scheduler is one of the crucial modules of any operating system. Operating system uses CPU schedulers based on the requirements. Fair Share CPU scheduler is preferable scheduler by many operating systems. It distributes fixed processor time amongst different parts of a system like groups, users etc. Fixed distribution of processor time can distress the performance of system. Moreover, traditional CPU schedulers ignore the impreciseness and uncertainty of the tasks. This work presents the Intuitionistic Fuzzy based Fair Share scheduler (IFFS). IFFS scheduler has extended the research in the field of the impreciseness of tasks. Intuitionistic Fuzzy Inference Systems, IFIS-DP and IFIS-DCS have been designed to share the CPU time dynamically and for assigning dynamic priority to each task. Experimental results prove the better performance of IFFS scheduler over FS scheduler.
