Abstract
The OPAL research reactor serves as a neutron source for diverse Neutron Beam Instruments (NBIs) undergoing commissioning throughout 2007 by The Bragg Institute of the Australian Nuclear Science and Technology Organisation (ANSTO) [1]. Port-based Systems Engineering (PBSE) using UML2.1.1[2] -and more recently SysML [3] with explicit physical flowport support - has been employed to support Model-Based Systems Engineering (MBSE) of NBIs, including reverse- and forward-engineering of Java components, and development of XML schemas for NBI hardware components and sensor-actuator device networks. Electronic systems, neutron flows, and vacuum systems are modelled as UML2 ports with custom notation and SysML flowports. The NBI models thus engineered are incorporated into a ModelServer system (implemented in Java+XML), which acts as a distributed, multi-client, control system façade that integrates low-level, logical device interactions (via a real or simulated control system) into high-level, physical instrument block models that support recursive control [4] and derived, controllable, physical system values.
Submitted to SoSym and reviewed but not published due to cancellation of the SoSym Model-Based-System-Engineering (MBSE) theme issue.
