An Intelligent Planning-Based Modeling Method for Diagnosis and Repair

الملخص EN

Planning and model-based diagnosis are both branches of artificial intelligence.

In model-based diagnosis, multiresults may be gotten which lead to an uncertain diagnosis.

We use the landmark method from planning to designing an event sequence to get a reaction.

A method that uses planning to repair in local results of incremental diagnosis is proposed.

Firstly, a model is established on model-based diagnosis and planning.

Incremental diagnosis results are used as the initial state of planning, and the heuristic search method is used to find the solution to an unfaulty state.

Two algorithms with different strategies are designed for diagnosis and repair: one is to repair all possible faults and use controllable events to repair them, and the other is to test through the feedback of controllable events and observable events to get the only solution and repair them.

At the same time, the efficiency of the incremental diagnosis method is improved based on heuristics.
