| Abstract： |
Based on the data obtained from a survey recently made in Shanghai,
this paper presents the hybrid technique for risk analysis and
evaluation of some diseases.
After determination of main risk factors of these diseases by analysis
of variance, the authors introduce a new concept 'Illness Fuzzy Set' and use
fuzzy comprehensive evaluation to evaluate the risk of suffering from a
disease for residents. Optimal technique is used to determine the
weights $w_{i}$ in fuzzy comprehensive evaluation, and a new method
`Improved Information Distribution' is also introduced for the
treatment of small sample problem.
It is shown that the results obtained by using the hybrid technique are
better than by using single fuzzy technique or single statistical
method. |
