Abstract:
Workflow processes are moving from long-lasting, well-defined, centralised business processes to dynamically changing, distributed business processes with many variants. Existing research concentrates on decentralisation and on adaptability but there is more to be done on adaptability in decentralised workflow systems. The aim of this research is to overcome the limitation of current workflow management systems by moving from a centralised workflow to a flexible decentralised peer-to-peer (P2P) workflow system. A P2P workflow management architecture is proposed which offers flexibility, exception handling and dynamic changes to both the workflow process definition and process instance level by applying a range of Artificial Intelligence (AI) techniques. An Exception Handling Peer (EHP) captures exceptions, from the workflow peers, characterises the exceptions and applies a recovery policy. Initial prototyping of the system has been carried out using JBoss jBPM whilst the P2P network
environment of this prototype is based on Sun MicroSystem’s JXTA.
