Temporal and hypothetical reasoning as a support for qualitative reasoning

To deal with complex problems, many kinds of reasoning and representation techniques are needed. The cooperation between different reasoning models constitutes one of the objectives of second-generation systems. The need to mix temporal and hypothetical reasoning for qualitative simulation is highlighted. A system built around an ATMS, a TCP, and a model that reasons on orders of magnitude is proposed. This system relies on an extension of HEART (see C. Joubel and O. Raiman, 1990). A new method for making histories concise has been developed.<
