Upon reviewing your comments, I believe you are linking the creation of a patient to a parallel flow of warehouse deliveries. I suggest implementing the parallel flow in a process flow that is not specific to the patient, but rather a general one. Attached is an example of how to synchronize these two flows.
The synchronization logic is in the "Create tokens" process, which triggers the separation and delivery from the warehouse and runs the flow in parallel. Meanwhile, the patient waits for this process to complete before proceeding with their own flow.
The attached example confused me, I'm new to FlexSim and I don't know much, is it possible to explain it within my simulation or explain it step by step in more detail?
Each patient arriving at the model is represented by a token and processed in an instance. Flexsim creates a copy of the process flow for each patient and runs it independently. The warehouse operates as a single process independent of the patients. In the model I have attached, the patient arrives at the hospital and can proceed to either reception or the waiting room. Then, they move to the Exam Table for the procedure. Finally, they move to the Observation Room and must wait for the warehouse delivery. The warehouse delivery is handled independently. To address this issue, I used the "Create token", which creates a token in the process flow representing the warehouse, and the delay represents the overall process (which can be further detailed). The "wait for event" function waits for the token to pass through the process to release the patient.
Hi Jao,
The problem is that when you listen to activities that belong to an instanced process flow, you need to define the specific instance that will trigger this source.
You can't do that in your model, since the instances will be the patients you create throughout the simulation and don't already exist. In this case, you should find another way of triggering when you need a new patient arrival.
I hope it helps!
I partially understand, but I don't know what to do to fix it.
Help me please.
In order to help you I need to understand what you're trying to do with all these blocks:
What I'm guessing is that you want to create 6 patients every time a token exits the "Process Sat 2" activity and 4 patients when exiting "Process Sat 1" activity. Is that correct? If not, could you explain it?
I'm working with deliveries made by the warehouse. In this case, all blocks are assistance sectors that will collect the material from the satellite pharmacy, but only after the warehouse has delivered it to satellites 1 and 2.
