Definition and Study of Lineal Equations on Order of Magnitude Models

摘要

In situations where there is a lack of quantitative data description, it is important to use equations where the operators and the coefficients are qualitative. In addition, the results obtained have to be the qualitative description of the quantitative information that we would obtain by usign numerical models. In this paper we define and study qualitative lienar equations by using qualitative operators consistent with R in a qulaitative model of magnitude orders.
