Abstract

OBANDO, Jorge Mario  and  YANEZ, Sergio. DATOS AGREGADOS Y DESAGREGADOS EN EL ANÁLISIS DE DATOS DE GARANTÍA. Rev.EIA.Esc.Ing.Antioq [online]. 2005, n.4, pp.43-53. ISSN 1794-1237.

Warranty data, statistically well handled, is useful to predict future claims, to make comparisons between products claims, to estimate products field reliability, and to identify reliability improvements that can be made to the product. This analysis requires the availability of daily records that sometimes are only available in weekly or monthly total (grouped data) due to the nature of the operations of the organization. In this work the effect of the grouped data in the final results of the analysis is studied.

Keywords : Reliability; warranty data analysis; counting processes; intensity rate.
