Editorial: The Seventh Interfaces Ranking of Universities' Contributions to the Practice Literature

For the seventh time, I rank universities according to their contributions to the INFORMS practice literature and trace the evolution of the rankings of the top universities. Two universities are tied for the top ranking this time: the Georgia Institute of Technology and the University of Pennsylvania. Erasmus University, the University of British Columbia, and the University of Chile are now tied for the top ranking among non-US universities. The number of non-US universities contributing to the practice literature is growing.
