  • Create
    • Start Process - 'Start Pick'
    • End Process - 'Order End'
    • Generic Process - 'MOD_Rack'
  • Select 'Mod_Rack', right click and select Convert to Base Module and then delete the process
  • Next use Auto-Create Processes to create as many rack aisles as desired.
    • Select Copy properties from the MOD process you created.
    • Be sure to enter a Middle as a naming convention
  • Reposition and Align the processes
  • Select an outside aisle and select Auto-Create Path
    • Select Vertical Single Side
    • Set the proper Path Direction
    • The proper Location for the Connectors
  • For inside aisles select both sides and Auto-Create Path
    • Set to Vertical Double Side
    • Location of connectors will default to in-between processes
  • Select an outside aisle and select Auto-Create Path
    • Select Vertical Single Side
    • Set the proper Path Direction and the proper Location for the Connectors
  • Use the Connector tool to place a connector at the end of each aisle and align them together
  • Connect the model together, extend the flow of each aisle with the connectors and connect the ends together. This will allow objects to bypass aisles
  • Select 'Start Pick' and in Define Object Creation Rules
    • Set Object type to Create to 'Default Object'
  • Go into Resources and Shifts
    • Create 'Picker' with Available Number '5' and click Add
  • Drag across the entire model and right click on a connection line and go into Item Properties.
    • Go into Select Speed/Distance/Capacity
      • Check both Speed based on Units/Sec and
      • Enable Auto-Distance calculation
      • Set Line Capacity to 5
      • Check Enable Line Capacity
      • Set Distance between Objects to 3
    • Next go into Resource Constraints
      • Set 'Picker' to 1
      • Under Default Override
        • Check Enable and Hold Resources until objects are activated at next process are activated at next process
  • Select Smart Module and Edit 'Mod_Rack'
    • In Process Timing Properties
      • Set Default Timing to a Min/Max or 15/25 Seconds
    • Then in Resource Constraints
      • Set 'Picker' to 1
      • Under Default Override
        • Check both Enable and Hold Resources until objects are activated at next process
    • Go into Process Capacity and Buffer and change Queue Capacity to 0
    • Next go into Process Extensions
      • Under ObjectNextProcessDefined
        • Insert a line, change it to an Expression Action
          • Select NextProcessToStart from the left and enter - 'Order End'
    • Use the Results Process and place a Results Process on the left side and add four parameters
      • Display -
        • Avg Pick Time
        • Avg Distance
        • Orders / Hr
        • Total Orders
      • Context -
        • Object
        • Object
        • Process

        • Default Object
        • Start Pick
        • Order End
      • Parameter -
        • Object Lead Time
        • Object Travel
        • Completed Object Count
        • Completed Object Count
      • Type -
        • Average
        • Average
        • PerHour
        • Cumulative
      • Format -

      • Change the Display Type to Text Values
  • Go into 'Start Pick'
    • Switch to Least busy/Randomized Routing
      • In here check Ignore on both ‘Connector’ and ‘Order End’
  • Switch to the Simulation tab and click Start
