It was motivated by two observations regarding modeling in general and work in qualitative physics in particular. First, all model-based reasoning is only as good as the model used (Davis and Hamscher 1988). Second, no single model is adequate or appropriate for a wide range of tasks (Weld 1989).}, number={1}, journal={AI Magazine}, author={Liu, Zheng-Yang}, year={1993}, month={Mar.}, pages={77} }
