How to make operator load items to agv without agv stopping?

When loading items onto agv's (without operators) I can prevent the agv from stopping by controlling the end speed. However, I don't know how to do that when an operator is loading the agv. If anyone could help me, I'd appreciate it.

Many thanks.

FlexSim 19.1.0

Hi @Ana S20,

Would you be able to upload the model you're working with? I'm not sure what's going on based on the description and so I'm not sure what to recommend. It sounds like this is something you could solve by using a triggered Move Object activity that would simply move the object from the operator to the AGV without performing an actual "unload" process. If you upload your model, I'd be happy to try and figure out how to make it work.

Otherwise, here's a small example of what I'm describing that you could possibly use in your model:

Hopefully this does what you're looking for and helps you come up with a good solution.

Hi, @tanner.p

Thank you for your answer.

Here is the model I'm working on.

However, I think your solution works alright.

Best regards.

Hi, @tanner.p

I'm sorry. Although your solution really helped, I'm having trouble trying to do the same with more than 1 task executor. I'm uploading my model so it's easier to understand what I'm doing wrong.

Thank you very much.

@Ana S20,

Thanks for the feedback. Is the model you've attached the whole model that you're building? Or will you be adding to it? For example, will you always have 6 AGVs traveling in a loop that load at Queue1 and unload at Queue2? The reason why I ask is because this logic tends to break when models get significantly larger.

I've updated your model to cycle through this loop indefinitely. Hopefully this is kind of what you're hoping to achieve.

@tanner.p

Hi. Thank you so much for your answer.
I won't add more AGVs. However, I'm adding this small model to a more complex production line. After adding this system to another model, I get this error and I can't figure what's missing:

I'd appreciate if you could answer a few questions regarding this model in particular:

1) Why do we need to create a task sequence twice in the AGV process flow?

2) What's the "Change Visual" for in the same proccess flow?

Thanks in advance. I'm a newbie so there are some basics I don't understand yet. I apologise if I'm asking redundant questions.

Best regards.
