Qualitative probabilistic networks have been introduced as qualitative abstractions of Bayesian belief networks. One of the ma jor drawbacks of these qualitative networks is their coarse level of detail, which may lead to unresolved trade-offs during inference. We present an enhanced formalism for qualita tive networks with a finer level of detail. An enhanced qualitative probabilistic net work differs from a regular qualitative net work in that it distinguishes between strong and weak influences. Enhanced qualitative probabilistic networks are purely qualitative in nature, as regular qualitative networks are, yet allow for efficiently resolving trade-offs during inference.
