Addressing decision problems in the medical field, DES helps in the evaluation of the likely consequences of incorporating a new technology in a particular healthcare system. This book covers the fundamental concepts of DES, including entities, attributes, the handling of time, events and their processing, time-to-event techniques, resource constraints and unconstrained models, queues, information handling, and replications. It also discusses when DES should be used, what its limitations are, and how it differs from the more commonly used Markov technique.
