Abstract

A system and method for distributed resource management in a computer network operating under control of workflow management software system (WFMS) to manage plural resources to perform a workflow process that includes multiple process activities, uses two-step resource assignment to manage resources at two levels. The resources are grouped by capabilities into resource groups controlled by a local resource manager (LRM), which maintains dynamic status of each resource, such as availability and load, as well as their roles and addresses. A global resource manager (GRM) stores resource data only about the groups: capabilities and status. The WFMS invokes the GRM, requesting a specified resource activity. The GRM checks the stored capabilities and status among the resource groups, selects the resource group capable of the specified activity and available, and forwards the request to the LRM for the selected group. The LRM selects one of the resources in the group to perform the specified activity and assigns the activity to that resource.
