Currently, a little research is underway on modeling the imprecision and uncertainty in conceptual data modeling and the conceptual design of fuzzy databases.
Rather than resorting to a traditional probabilistic approach for modeling the imprecision on product demands, this work proposes an alternative treatment by using fuzzy concepts.
Fuzzy set theory was proposed by Zadeh in 1965 to mathematically model the imprecision inherent to some concepts [ 41].
Our previous application of structural equation models showed that the imprecision in hair mercury analyses is substantial and can produce underdetermination of neurotoxic impacts of methylmercury exposures (Grandjean et al. 2003a).
The proposed WMRC utilizes sliding mode control to cope with the model imprecision of a conventional reduced first-order HVDC model and selects the area center of inertia (COI) signals as the feedback signals.
Opponents of C2 use the imprecision of these models and poor academic behavior to attack C2 in the same way advocates of smoking belittled the science of cigarette smoke.
Perhaps most notably, because of the imprecision of these growth models, various sources of bias, and year-to-year variation in students and conditions, very few teachers manage to be "top" teachers for three, four or five consecutive years.
Current models derived from regression are limited by the imprecision of GFR estimates.
Nonlinear effects are included in the structural formulations and a fuzzy methodology is adopted for handling the imprecision present in the structure modeling.
FESs have proven to be an important tool for modeling complex systems, in which, due to the complexity or the imprecision, classical tools are unsuccessful.
