Resource scheduling in workflow management systems
First Claim
1. A computerized method for resource handling within a Workflow Management System (WFMS), said WFMS administrating execution of a process-model of a business-process wherein said process-model comprising at least a first activity and a second activity, said method comprising the steps of:
- determining said process-model of the business-process comprises a first resource-specification associated with said second activity, said first resource-specification comprising;
at least one first resource-identification of a first resource required for execution of said second activity, andan assumed first waiting time period for said second-activity specifying a time required after a first allocation request until said first resource is actually available for said second activity,requesting allocation of said first resource on behalf of and at least said assumed first waiting time period in advance of starting execution of said second activity,monitoring within said requesting allocation step an actual waiting time period required after said allocation request until said first resource is available,updating said assumed waiting time period to a new assumed waiting time period in said process-model of the business-process based on said actual waiting time period; and
starting execution of said first activity followed by said second activity.

Abstract
A system for improved scheduling of resources within a Workflow-Management-System or a computer system with comparable functionality (WFMS). Based on a new resource specification comprised within a process model and associated with an activity, the WFMS determines the resources required for execution of said activity. The invention further schedules a request for allocation of said resources on behalf and in advance of starting execution of said activity. This approach reduces the execution time of the activity as all resources required by the activity will be available when execution of the activity begins; the activity does not have to wait for these resources. Moreover, a WFMS knowing the required resources of the activities it is administrating is able to schedule resource requests to avoid resource conflicts between the activities.
