The ability to automatically read the current state of a system to (design for easy detect and diagnose the root causes of output product defects, and diagnostics) quickly correct operational defects.
of a system is generally computed from the model of the system.
NICTA does fundamental research on many aspects of automated planning and model-based diagnosis: from path finding to classical planning (satisficing and optimal) to probabilistic and temporal planning, and from diagnosis of circuits, to diagnosability
analysis of discrete-event systems and networks of hybrid continuous and discrete systems.
The goal of the paper was not to generate the best test sequences, but rather to evaluate and compare the diagnosability
Among the topics are an efficient task allocation protocol for point-to-point multi-agent systems, the distributed execution of workflow using parallel partitioning, secure logging for auditable file systems using separate virtual machines, a designated-path scheme for energy-efficient data aggregation in wireless sensor networks, a mechanism based on hypervision for monitoring and controlling a system, and the conditional diagnosability
of twisted cubes under the comparison model.
The MVIM method, which can assess the diagnosability
of the system and use that for sensor selection/optimization, has been applied to tool breakage detection in turning, as well as fault diagnosis of helicopter gearboxes.
However, complexity and lack of diagnosability
greatly reduced its usefulness.
