A priori and a posteriori error bounds were derived and a computational study was performed to (a) test the correlation between the a priori, the a posteriori, and the actual error and (b) quantify the difference of the error bounds from the actual error. Based on the results we conclude that calculating the a priori error bound can be considered as a useful strategy to select the appropriate aggregation level. The a posteriori error bound provides a good quantitative measure of the actual error.119-134engclusteringnetwork modelsapproximation algorithmsUsing error bounds to compare aggregated generalized transportation modelsArtigo10.1007/s10479-006-0051-6WOS:000241496900008Acesso restrito
