Warehouse Using Random Pick Simulation

Warehouse Racks and Aisles Pt 1

• Create a Start and End process
• Create two processes –
  • Rack Module 1
  • Rack Module 2
• Select Rack Module 1 –
  • Change the timing
  • Capacity
  • Display settings
    • In Display Settings 2D/3D
      • Change the 3D Process Image
      • Size of the process
      • Rotation of the process - this may take some adjusting
• Select Rack Module 2 –
  • Change the timing
  • Capacity
  • Display settings
    • In Display Settings 2D/3D
      • Change the 3D Process image
      • Size of the process
      • Rotation, this may take some adjusting
• Select both Modules –
  • Process Extension/Event Handling
    • Select Object:NextProcessDefined
      • Insert and Expression, Edit
        • Select NextProcessToStart and type 'End'
• Select each Rack Module
  • Convert each to a Base Module
• Select Auto-Create Processes –
  • Drag the area
  • Change number and direction of processes to the desired
  • Apply properties from a module
  • Check side-by-side to make the processes up against one another
  • Then choose the value to be displayed for the label
• Repeat this process as many times as desired
• To Auto-Create Paths –
  • First select the processes to create paths between
  • Change Path Type to Create
  • Path Direction
  • Connector Location
  • Process Path, this will be based on the processes you selected
• Finish the connections between all needed processes
• Select the Start process
  • Change the Routing Properties to Least Busy/Randomized Routing –
    • Evenly distribute work among processes, make sure Connector and End are checked for ignore.
• Go to Flow Properties
  • General Properties
    • Change the Search Depth to a number greater than the number of processes you have, this ensures that all processes are seen by the routing.
• Run the Simulation
• Go to View - 3D View to switch and see the aisle and racks

Warehouse Racks and Aisles Pt 2

• In order to edit the modules that were created for the racks navigate to Model Build
  • Select Smart Module, then hit refresh list to update the module list.
  • Select Edit to make adjustments to the modules, this will automatically update all processes that were setup using the module.
  • Since Rack Module 1 and Rack Module 2 were converted into Base Modules, they are no longer useful and can be deleted.
• By viewing the Item Properties of a process and extending the window you can see if a process is based on a module and which if so which module.
• Let's make some changes to Rack Module 1
  • Change the timing, loading and unloading
  • As well as the queue and process capacity
• Now select any process based on Rack Module 1 and notice how the changes have been made.
• Select Resource and Shifts
  • Add a new resource called Forklift and add 2 of them
• Select all of the lines between the racks and add Resource Constraints –
  • Enable Override and Hold Resources
  • Check apply to all as well
• Run the simulation
• Stop the simulation
  • Add more resources
• Run the simulation
