Title: Integrated Staffing and Scheduling for Surgeries Authors: Sandeep Rath, Kumar Rajaram, Aman Mahajan
Abstract: We consider the problem of minimizing expected resource usage and overtime costs across multiple parallel resources such as anesthesiologists and operating rooms which are used to conduct a variety of surgical procedures at large multi-specialty hospitals. To address this problem, we develop a two-stage stochastic dynamic programming model with recourse. We develop a data driven robust optimization method that solves large-scale real-sized versions of this model close to optimality. We validate and implement this model as a decision support system at the UCLA Ronald Regan Medical Center. Initial testing has indicated significant cost savings. In addition, the insights based on this model have significantly influenced decision making at the operating services department at this hospital.
