Workflow execution on large-scale heterogeneous distributed computing systems, such as grids, requires a complex coordination. Activities of workflow patterns must be matched with entities the system that possesses highly dynamic properties. We pinpoint key concept coordination actions according to actual and local conditions-analogously chemical reactions. Modeling enactment molecules reactions, formalized in nature inspired /spl gamma/-calculus, yielded an autonomously evolving, distributed, decentralized model can adapt dynamically changing environment.
