Phase 1: In Phase 1, task graphs are equivalent to flowcharts containing two kinds of nodes: Action (A) and Observation (O) nodes (Mittal, S. Bobrow,D.G. de Kleer, J. 1988).

The authors claim that a plan based approach to diagnosis is most appropriate for complex systems containing many different kinds of subsystems which change in ....
