Autonomic Workflow Management in the Grid

摘要

The autonomic workflow engine enables workflow to be dynamically specified and adapted using Event-Condition-Action rules. A new approach to 'autonomic execution of workflow processes based on matrix-based formulation was adopted that, together with the Petri net marking transition equation, provides a full dynamical description of a workflow system. We have built a workflow that models Traffic-information-grid-based Mobile Navigation Service to illustrate the quality of self-management using DEC through awareness of the computational environment.
