摘要：Cloud computing has emerged as a promising platform that grants users with direct yet shared access to computing resources and services without worrying about the internal complex infrastructure. As a cloud must provide services to many users at the same time and different users have different QoS requirements, the scheduling strategy should be developed for multiple workflows with different QoS requirements.Task scheduling problems are premier which relate to the efficiency of the whole cloud computing facilities. Task scheduling algorithm is an NP- completeness problem which play key role in cloud computing. The paper deals with Multiple QoS Constrained Scheduling Strategy of Multi-Workflows to address this problem. The proposed strategy can schedule multiple workflows which are started at any time and the QoS requirements are taken into account and are able to increase the scheduling success rate significantly in a decentralized environment
