How to Model a Multi-Operator Assembly and Packaging Process in FlexSim?

WhatsApp Video 2024-11-12 at 12.32.49.mp4Esquema Final.fsm
Hello everyone,

I'm working on a project in FlexSim and need assistance modeling a specific process of assembling and packaging panels on a production line. Below is a detailed description of the workflow:

  • Operator 1:

    • Responsible for initially labeling the plastic bag and Delivers the labeled bag to Operator 2 across a shared worktable. (2 seconds)
    • While Operator 2 opens the bag and prepares for packaging, Operator 1 assembles the next panel (base, kit, and cover) and prepares the next plastic bag. (4 seconds)
  • Operator 2:

    • Receives the labeled plastic bag and opens it. (2 seconds)
    • Packs the assembled panel into the opened plastic bag and Transports the packaged panel to the sealing machine. (4 seconds)
  • Both operators work face-to-face, with a shared worktable between them, facilitating a continuous flow of activities.

  • Operator 3:

    • During the sealing process, is responsible for opening and assembling cardboard boxes. (12 seconds)
    • Places the sealed panels into the boxes until they reach maximum capacity. (2 seconds)
    • Closes, labels, and transports the filled boxes to the stock pallet. (20 seconds)

My questions are:

  1. How can I configure the operators and their specific tasks in FlexSim?

    • How do I assign sequential and parallel activities between Operators 1 and 2?
    • How can I represent Operator 2 waiting for Operator 1 to finish assembling the panel?
  2. How do I model the shared worktable between Operators 1 and 2?

    • Should I use a static resource, or is there a better way to represent this interaction in FlexSim?
  3. What is the best way to synchronize the activities among the operators?

    • How can I ensure that Operator 3 starts assembling the boxes while the panels are being sealed?
  4. How can I represent the flow of materials (plastic bags, panels, cardboard boxes) throughout the process?

    • Should I use conveyors, queues, or another specific tool in FlexSim?
  5. How do I implement the sealing process and the maximum capacity of the boxes?

    • Is there a way to define the box capacity and automate the closing and labeling when they are full?

I would greatly appreciate any help or guidance on how to effectively model this process in FlexSim.

Thank you very much!

packaging_squence.fsmIt looks like a sequence of combiners. They are loaded by operators.

Hello Marcio!


I have verified that the process flow of the model is not activated. If possible, it would be more interesting to model these activities in Process Flow.


As for question 1 and 3, I believe it is easier for you to use the sequential activities feature to distribute the activities among other operators. On the website there is a breakdown of how this function works: https://docs.flexsim.com/en/24.2/Reference/ProcessFlowObjects/TaskSequences/CreateTaskSequence/CreateTaskSequence.html


Há também um tutorial disponível sobre este assunto: Tutorial Task 5.1 - Create a Custom Fixed Resource


To model the shared worktable between Operators 1 and 2, from the attached video I believe that it is not necessary to represent in a shared way, I could allocate each one a Queue and only represent in 3D as a single location.


For question 5, also in Process Flow, you can assign labels to define the capacity of the boxes and control that flow.


Hope this helps in your work!
