Simulation framework to analyze Operating Room release mechanisms

Rimmert van der Kooij, Martijn R.K. Mes, Erwin W. Hans
2014 Proceedings of the Winter Simulation Conference 2014  
For this inflexibility, we introduce the concept of releasing ORs, and present a generic simulation and evaluation framework that can be used by hospitals to evaluate various release mechanisms.  ...  The block time (BT) schedule, which allocates Operating Rooms (ORs) to surgical specialties, causes inflexibility for scheduling outside the BT, which negatively affects new surgeons, new specialties,  ...  ACKNOWLEDGMENTS We like to express our gratitude to Vanderbilt University and Medical Center in general and in particular to Jesse Ehrenfeld, Vikram Tiwari, and Beth Adame without whose support and information  ...
