ARENA

• General-purpose simulation package
• Process-oriented
• High-level
• Hierarchic
• Animation
• Model building
• Drag-and-drop modules into model window
• connect them, so define flow of entities
• detail modules and entities in dialog boxes and
  in spreadsheet
• Run independent replications

Project Bar (Basic Processes)

• Flowchart Modules
• Data Modules

6

• Look at first Model MM1 with Assign and Record
• Flowchart Modules
• Create Process Dispose / Assign Record
• Data Modules
• Entity Queue Resource Variable
• Animation
• Connections
• Run Conditions
• Running Model MM1 with Assign and Record
• animated
• fast
• Look at the report

7

• Build your first model M/U/1 Queue, Drill
• Drag and drop modules from the project bar
• Create (parts arrive)
• Station queue drill
• Delete (parts leave)
• Complete the spreadsheets in the spreadsheet bar
• Define model features like distributions for
  interarrival times and service times, station
  type queueing system
• Add suited names
• Actualize data modules
• Add suited names, queueing discipline
• Add some animations from the tool bar
• Nice icons in CProgramme/Rockwell Software/Arena
  / .plb
• Run - menu
• Look at the results - reports

14

• Variables, global, used in expressions
• Predefined, e.g.
• TNOW Simulation clock,
• NQ(queue ID) numer of entities in the queue,
  
• NR(name) number of busy resource units(servers)
• User-defined in data module Variable
• Attributes of Entities, user-defined in an
  Assign data module, used in expressions
• Record, flowchart modul, collects data, defines
  statistical accumulators, stores data in them
• Example MM1 with Assign and Record

15

• Decide module
• Routes the entities in two different directions,
  depending on the value true or false of a
  logical expression
• Histograms
• Continuous time statistics
• Example Histogram Continuous Time Decide
