Demonstrate your operation research mojo by answering, 'Queuing theory is a branch of operations research that focuses on problems that involve queuing (or waiting). Typical examples might be bank customers waiting for service or computers waiting for a response. Problems involve the matching of servers provided to randomly arriving customers or services, which takes a random amount of time. A queueing model is constructed so that the length of queues can be known and their waiting times predicted and thereby optimized. Knowing how to reduce queue times is a valuable skill and brings many benefits to a wide array of organizations.'

Tip: Keep in mind that there is software that manages queue problems, but you'll need to understand sophisticated wait management systems and the six main ways to reduce queue wait times to analyze, optimize and manage these types of systems and their optimization.
