Tracking Automated Shuttle Fault Isolation Through use of Aspects1

摘要

Fault detection, isolation, and recovery are some of the most critical activities in which astronauts and flight controllers participate. An agent-oriented diagnosis system has been built using JACK, an agent-oriented programming language. An important feature being added is a system-activity tracking mechanism that allows the user to observe what the agent system is doing. This mechanism is then generalized for all JACK agent systems. By using AspectJ, an aspect-oriented tool, a plug-and-playable tracking system can be built that can add the capability to track the activity of the system to any JACK agent system easily.
