Yet, almost all&nbsp;analytical results in the literature remain exclusive to single-server queues with infinitely&nbsp;patient jobs and under exact job-size information, which are assumptions that clearly do&nbsp;not hold in service systems such as call centers or healthcare facilities. In this work, we&nbsp;provide the first analytical results on the performance of size-based scheduling in&nbsp;multiserver queues with abandonment and inexact job-size information.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>About Rouba Ibrahim<\/strong><\/p>\n\n\n\n<p>Rouba Ibrahim is a professor at the School of Management of University College London, where she currently heads the Operations &amp; Technology group.
