Plan-Based Diagnosis and Recovery\n

Plan-Based Diagnosis and Recovery
The plan-based diagnosis and recovery system works with both the new resource manager and Planlet to make the room more robust. As our spaces become more complex, it becomes more and more difficult for users to understand what is happening in the room when a specific task is being carried out. As a result, when the room experiences a failure it is difficult for a user to manually isolate and recover from the problem. This system is designed to automatically deal with various types of failures in a way that is transparent to the user.

All tasks in the room can be broken down into steps, which can be strung together to create a plan. When a step in a plan fails, this system is designed to isolate the problem and generate a solution. Using Bayesian nets, the exact failure point is determined. This information is then used by recovery and the resource manager to devise a solution, which would allow the plan to continue unimpeded. This process is automatically triggered by the failure and requires no action on the part of the user.
