Reliable Execution of Business Processes on Dynamic Networks of Service-Enabled Devices

It is expected that future shop-floors will be populated by thousands of networked embedded devices. Those will not only communicate using IP (as in TCP/IP), but also feature some autonomy, allowing them to collaborate among themselves and with enterprise systems. As they can offer both their mechatronic and higher-level functions as a service and support dynamic deployment of new code, they can execute business logic locally, allowing for new classes of business processes that are executed collaboratively by back-end and embedded systems. While some parts of a process will still be executed in the data centre, the rest will execute directly on embedded devices on the shop-floor. Business Process execution will therefore be more dynamic and context-based. We introduce an approach to manage efficient business process execution over such highly dynamic infrastructures.
