“…Pawlak 39 implemented the TOC to support the nurse workforce shortage and to find the influence factors. Peltokorpi et al 40 applied TOC tools, such as the Current-Reality Tree (CRT), to improve the throughput in a forensic DNA laboratory. Despite the effectiveness of the TOC, it has not been used to examine the throughput of critical resources of the OR theater.…”

The management of costly and limited healthcare resources, such as operating rooms, doctors, nurses, and beds, is challenged by the uncertainty of arrivals and the service time of different types of patients. Therefore, healthcare units encounter unbalanced utilization of such resources and unnecessary long patient waiting times. A system dynamics model simulating a typical medium-sized hospital, where different types of patients are served using the same limited resources, is developed to implement the Theory of Constraints philosophy. The AnyLogic environment is used for execution. The model is used to identify the system bottleneck resource, then to exploit and to subordinate the system around this resource. The number of served patients (throughput) is increased by 6% without any resource elevation. Furthermore, the model is used to determine the proper capacity needed to elevate the bottleneck resource.
