Notes:
In manufacturing Grid workflow, multiple tasks share a common and limited resource pool.In order to solve task scheduling in multi-process with resource constraints under MG workflow, theTask-Resource Constrained model is set up to descript the assignment relation between task andresource. The framework of the task scheduling and the scheduling policies are also presented thatcan readjust the tasks according to the priority rules and the time parameters in the process. Then wepresent a heuristic scheduling algorithm that includes multiple policies. The heuristic schedulingalgorithm will update the critical path of DAG (Direct Acyclic Graph) and the beginning time ofpost-tasks. MG Workflow engine can dynamically schedule the resources according the taskrequirement. An example is given to illustrate the method at last
