dc.description.abstract | In most cases the models for experimentation, analysis, or design in engineering applications
take into account only quantitative knowledge. Sometimes there is a qualitative knowledge
that is convenient to consider in order to obtain better conclusions. These qualitative concepts
can be labels such as ``high,’ ’ ``very negative,’ ’ ``little acid,’ ’ ``monotonically increasing’ ’
or
symbols such as ¾; º, etc. . . Engineers have already used this type of knowledge implicitly
in many activities. The framework that we present here lets us express explicitly this
knowledge.
This work makes the following contributions. First, we identify the most important classes
of qualitative concepts in engineering activities. Second, we present a novel methodology to
integrate both qualitative and quantitative knowledge. Third, we obtain signi®
cant conclusions automatically. It is named semiqualitative reasoning.
Qualitative concepts are represented by means of closed real intervals. This
approximation is accepted in the area of Arti® cial Intelligence. A modeling language
is speci® ed to represent qualitative and quantitative knowledge of the model. A
numeric constraint satisfaction problem is obtained by means of corresponding
rules of transformation of the semantics of this language. In order to obtain conclusions,
we have developed algorithms that treat the problem in a symbolic and numeric way. The
interval conclusions obtained are transformed into qualitative labels through a
linguistic interpretation. Finally, the capabilities of this methodology are illustrated on
different problems. | es |
