Efficient applications of expert systems to project risk management problemsare seldom, if not unusual. In this paper we overcome this lack by using the probabilisticexpert system shell SPIRIT. The rule-based shell’s power in conditioning, inference andreasoning under incomplete information...

Bayes-Nets are a suitable means for probabilistic inference. Such nets are very restricted concerning the communicationlanguage with the user, however. MinREnt-inference in a conditional environment is a powerfulcounterpart to this concept. Here conditional expressions of high complexity instead...
