The Impact Factor is established by dividing the number of times articles published in 2015 and 2016 were cited in 2017, based on a search of the Science Citation Index Database, by the number of articles published in the previous two years (2015 and 2016).
The 5-year journal Impact Factor is the average number of times articles from the journal published in the past five years have been cited in the JCR year. It is caclulated by dividing the number of citations in the JCR year by the total number of articles published in the five previous years.
This information will be updated on summer 2019.

In 2013, SORT has also renewed the certificate of excellence given in 2011 by Fundación Española para la Ciencia y la Tecnología which guarantees publishing and scientific quality for the next three years. SORT represents the third series of the Quaderns d'Estadística i Investigació Operativa (Qüestiió), published by Idescat between 1992 and 2002, which in turn followed from the first series "Quaderns d'Estadística, Sistemas, Informàtica i Investigació Operativa" (1977–1992). The three series of Qüestiió have their origin in the "Cuadernos de Estadística Aplicada e Investigación Operativa", published by the Universitat Politècnica de Catalunya until 1977.
