A Novel Fuzzy Logic Based Operating System Scheduling Scheme
Abdul Kareem,Varuna Kumara 한국지능시스템학회 2024 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.24 No.1
For a computer-based system, a set of processes must be scheduled such that every process iscompleted within its deadline. CPU scheduling is the process of allocating CPU among variousprocesses in a multi-processing system. The decision to allocate the CPU to a process has totake into consideration all aspects, including its priority and execution time, as scheduling isguided by a number of factors other than the execution time or priority. It is no longer onedimensionaland has become a multidimensional problem with vagueness and uncertaintiessuch as different CPU loading scenarios. The vagueness and uncertainties associated withthe decision to allocate a CPU to a particular process can be addressed using a fuzzy logicapproach. In this study, we propose a fuzzy logic based algorithm for CPU scheduling. Theproposed algorithm was compared with conventional scheduling algorithms for different CPUloading scenarios. The proposed method can schedule and execute all processes well withinthe deadline with a reduced average turn-around and a reduced average waiting time. Fromthe comparison results, it is evident that the proposed algorithm outperforms conventionalalgorithms in terms of the average turn-around and waiting times.
