Similarity weight method and its application based on the attribute synthetic evaluation system / 中华流行病学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore a way of determining the weights of variables in synthetic evaluation.</p><p><b>METHODS</b>Based on the attribute synthetic evaluation system, similarity weight was used to cluster and rank the atmospheric quality on 11 large cities.</p><p><b>RESULTS</b>Realized the classification and ranking for the atmospheric quality of the cities given, the results were almost comparable to that achieved by Topsis evaluation.</p><p><b>CONCLUSION</b>The method of comprehensive assessment using similarity weight in the attribute synthetic evaluation system seemed to be objective and rational. Not only it embodied the weights of variables involved, but also exploiting the information presented by the sample.</p>
