The imprecision and the uncertainty of many systems can be expressed with interval
models. The results of the simulation of these models can be represented by envelopes …

Gas turbines are critical to the operation of most industrial plants, and their associated
maintenance costs can be extremely high. To reduce those costs and increase the …

The 'ALARM'research group has been running two years as a multi‐labs group within the
French National Program on Artificial Intelligence PRC‐IA. The group's objective was to …

After preliminary work in economics and control theory, qualitative reasoning emerged in AI
at the end of the 70s and beginning of the 80s, in the form of Naïve Physics and …

After a brief overview of the work on causality in the area of qualitative reasoning, this paper
proposes an algorithm for causally ordering the variables appearing in a set of equations …

This paper gives an overview of the TIGER system in use at Exxon Chemical at Fife Ethylene
Plant in Scotland. It gives a summary of the plant and the usage of the GE Frame 5 two shaft …

An interval model can express the imprecision and the uncertainty associated to the
modeling of a system. The result of the simulation of one of these models can be …
