In this thesis, I created a tool for a particular VA clinic to simulate the delays veterans face in a network of mental health programs. Based on queueing theory, including blocking and reneging, different operations management strategies are compared using this discrete event simulation tool. To simulate wait times, users input arrival rates, service times, patience, probabilities of relapses and probabilities to go from one program to another. We determine that blocking is one of the main drivers of the delays. This model is not only useful for direct decision making, such as increasing capacity in one of the programs, but also to enable systems thinking in the VA. Indeed, if more quantitative methods were used at different levels of the organization, managers could take more informed decisions faster. This also prompts for rigorous data collection, which is something the VA needs, especially wait times for mental health clinics.
