Discrete event scheduler We have discussed several different issues to consider when designing the schedule for your agent-based model. There is one other approach to scheduling that we did not discuss in this chapter. Discrete Event Scheduling (DES) is when the agents and the environment of your model schedule events to take place at discrete times. For instance, examine the Mousetraps model in the Mathematics section of the models library. Right now, whenever a ball flies through the air it simply moves until it comes to a resting place and then attempts to trigger a mousetrap. Instead of this method, you could imagine implementing this model without any ball agents; instead, when a mousetrap is tripped, it schedules two other mousetraps to trip within a radius at a certain time in the future. This would be a discrete event scheduler. Reimplement this model using a DES.
