Abstract: We present a planning architecture that integrates five techniques: (1) representation of state information in a belief network with quantitative and qualitative propositions, (2) representation of a complex dynamic system (patient) as a state-space dynamic model, (3) incremental updating of parameter estimates in a probabilistic framework, (4) optimization of control variables for planning, and (5) assessment of a multiattribute value function based on decision theory. VentPlan implements this architecture to provide therapy plan recommendations for patients in an intensive care unit.
