Slide Mô phỏng sự kiện rời rạc - Discrete Event Simulation

Discrete event simulation
•Simulation time != real time
lKey ideas:
•A Queue
•A Queue is a queue, no matter how implemented.
•Different kinds of random
•Straightening time
•Inserting it into the right place
•Sorting it afterwards
lBuilding a discrete event simulation
•Graphics as the representation, not the real thing: The Model and the View

Don’t use a Continuous Simulation

We don’t want to wait that number of days in real time.
We don’t even care about every day.
•There will certainly be timesteps (days) when nothing happens of interest.
lWe’re dealing with different probability distributions.
•Some uniform, some normally distributed.
Things can get out of synch
•A Truck may go back to the factory and get more product before a Distributor gets back.
•A Distributor may have to wait for multiple trucks to fulfill orders (and other Distributors might end up waiting in line)
