Abstract

This paper investigates a chemical workflow enactment model that is intended to coordinate workflows of large set of activities on a large number of resources in a self-evolving nature, based on a chemical analogy. The concept of chemical workflow engine is introduced for a concurrent, self-coordinating enactment exploiting as much parallelism as inherently present. The concept is aimed at supporting a generalized workflow language without any restrictions, modeling most workflow patterns, separating data and control flow, supporting dynamic changes by multiple versions and instances. The paper presents the notion and model of the chemical based coordination.
