Scheduling in cloud computing environment using analytic hierarchy process model

Scheduling of tasks in distributed environment requires decision making approach for fair utilization and allocation of computing resources. In this paper, a scheduling model based on analytic hierarchy process (AHP) is discussed. The user tasks are compared using pair-wise comparison matrix and the machines are allocated on the basis of task priority. The paper also discusses an inconsistency identification method to determine the inconsistent element and to improve the consistency ratio of pair-wise comparison matrix. The proposed method is suitable for scheduling of tasks of different nature depending on different resources requirement like processing power, main memory, bandwidth etc.
