Describe the operation
Model arrivals, queues, resources, processing times, and routing using the familiar GPSS block-and-transaction approach.
Discrete-event simulation
Understand the queue.
Explore the choices.
What happens when more work arrives, a machine fails, or another person joins the team? Explore the consequences with GPSS/CK before changing the real system.
From a model to a better decision
Try the alternatives
Investigate staffing, capacity, inventory, and reliability. Change an assumption and compare what happens.
Understand the evidence
Study waiting times and resource use, account for uncertainty, and ask whether the results support your decision.
