1. MECH 3550 : Simulation & Visualization
Go Through the Syllabus, Introduce myself

2. Basic Simulation Modeling
The Nature of Simulation
The act of using computers to simulate the operations of various real-world processes
Analytical Solution

3. Systems, Models, and Simulation
A system is defined as a collection of entities that act and interact together to accomplish a logical goal.
There are two types of systems:
Discrete: Variables change instantaneously at separated points in time.
Continuous: Variables change continuously with respect to time.
Examples
Discrete-Bank
Continuous-???

5. Static vs Dynamic Simulation
Static Simulation:
Not dependent on time.
Dynamic
Time Dependent Simulation

6. Deterministic vs Stochastic
Contains no random components
Stochastic
Contains random aspects of input and output as well

7. Continuous vs Discrete
Modeling of a system where state variable change continuously over time.
Discrete
Modeling of a system at individual points in time.

8. Discrete Event Simulation
Dynamic
Stochastic
We will mainly be discussing these

9. Flow Chart for Arrival Routine, Queueing Model
Arrival Event
Schedule the next arrival event
Is the server busy?
Yes No
Set delay=0 for this customer and gather statistics
Add 1 to the Queue
Yes
Is the queue full?
Write error message and stop simulation
Add 1 to the number of customers delayed No
Make the server busy.
Return
Store time of arrival of this customer
Schedule a departure event for this customer

10. Flow Chart for Departure routine, queuing model
Departure Event
Is the queue empty?
Yes No
Subtract 1 from he number in queue
Make the server idle
Compute delay of customer entering service and gather statistics
Add 1 to the number of customers delayed
Schedule a departure event for this customer
Eliminate departure events from consideration
Return
Move each customer in queue (if any) up one place.
