AutoMod Syntax

• arriving
• begin
• end
• wait for
• print
• absolute clock

Example 4.1Two-Process Model

• Model examp04_1

4
Two-Process Model

• Loads arrive exponential 12 min
• Sorting
• uniform 10, 2 min
• Processing
• prep time 100 sec
• processing time uniform 8, 5 min
• unload time 20 sec

5
Two-Process Model

• Print message after sorting
• specific load was just sorted
• time that load left
• Simulate for 8 hours

Notes

• Some are capitalized, some not
• P_start, P_next
• User defined
• key words
• Not capitalized
• begin, arriving, wait for

Notes (cont.)

• AutoMod is load driven
• begin and end
• /comments/
• White space doesnt matter

9
Distributions

• constant 90
• sec is default
• normal 20, 2 min
• triangular 16, 20, 30 sec
• exponential 2 hr
• n normal, t triangular, e exponential

10
Clock

• In seconds
• absolute clock
• absolute clock/3600 is in hours
• ac absolute clock

11
Relative Clock
12
Loads exit the model

• send to die

13
Run Control

• Could run model now
• Stop with intervention
• Run control
• Click on Run Control in the Process System
  palette
• Click on New in Run Control menu
• Type 8 in Define Snap Control menu
• Click on OK

14
Keyboard

• Use p key to toggle between pause and continue,
  or use Drop Down menu
• Use D and d to increase or decrease time between
  screen updates
• Animate On/Animate Off with the g key
• Keyboard help with h

Order of Model Creation

• There is no one correct way of creating an
  AutoMod model. Below is one approach you may use
  when creating a model.
• 1. Create your movement systems (if any), except
  for vehicle scheduling.
• 2. Create the process system, define your source
  file(s), and enter the process procedures.
• 3. Define all your process system entities as you
  exit the source file.
• 4. Define load creation specifications.
• 5. Place graphics for process system entities
  (queues, resources, etc.).
• 6. Create vehicle scheduling if needed.
