Behavior Abstraction for 'D-actable Simulation

Most qualitative simulation techniques perform simulation at a single level of detail highlighting a fixed set of distinctions . This can lead to intractable branching within the behavioral description . The complexity of the simulation can be reduced by eliminating uninteresting distinctions . Behavior abstraction provides a hierarchy of behavioral descriptions allowing the modeler to select the appropriate level of description highlighting the relevant distinctions . Two abstraction techniques are presented . Behavior aggregation eliminates occurrence branching by providing a hybrid between a behavior tree representation and a history based description . Chatter box abstraction uses attainable envisionment to eliminate intractable branching due to chatter within a behavior tree simulation .
