Deadline allocation in a time-constrained workflow

Abstract

Workflow management systems should efficiently manage workflow constraints such as time, resource, and cost during workflow executions. Especially, workflow time management is important in timely scheduling of workflow process execution, avoiding deadline violations, and improving the workflow throughput. Though there have been some studies on the dynamic deadline management in a workflow, the importance of the static deadline management has not been much addressed in the past. We first describe our workflow model considered in this paper. Then, we propose a static deadline allocation method that can facilitate an efficient workflow processing. The proposed method can achieve high workflow throughput by analyzing the interrelated workflow components. We also present various experimental results that show the usefulness and efficiency of the method.
