The Mechanism of Workflow Task Execution in Migrating Workflow Management System

Migrating workflow is a new workflow management pattern that migrating instance migrates in workplaces and completes one or more workflow tasks. The workflow task execution machine which is installed on the workplace has the responsibility of receiving the task delegation of migrating instance and completing one or more workflow tasks according to the task logic of delegation and the service rule in the local space, by referring the workflow resource and workflow service in the background work machine network. In this paper we discuss the workflow task execution model and propose a task execution scheduling algorithm. The installing of workflow task execution machine is propitious to improve the flexibility of workflow service and the security of workplace. It also can lightweight the workflow instance.
