how to load a item with two or more operators

hi all
sometimes ,if want to move heavy or big thing, we need two or more people to move it together. how to realize this logic in Flexsim?
i try it using CTS, but the model don't run correctly! the item change the location between operators,finally only just one op hold the item. i want to those operators hold the item together,and then bring to destination!

you have any idea? please give me a hand! thanks!

Maybe this helps you!?

hi ,Setbastian
thanks for your linking .i look into those models.
but there is no method can solve my problem. what i want to solve is how to load a item with two or more operators. just like moving a big stone,we needs more than two peole together to lift it .

Using a coordinated tasksequences is the correct way so maybe you made a mistake in your sequence. Can you post a small demo model with the tasksequence that you have tried? Then maybe someone can take a look and help you.

Had been sure we had this topic in any other thread before. But can´t find it.

Solution at this time, as far as I remember, had been that you have to solve some different difficultys.
1. You have to go sure, that all involved Operators are available and loading starts even as soon as both are at loading station.
2. One Item can´t be on two Operators same time. So only one will do the real transport, the otherone will only walk. You will need Tasksequences anyway.
3. It seems to be very difficult to beware the Operators walking to exactly same position. Because in Flexsim, in opposit to reality, it is possible that more than one Operator can be at one point. This maybe can be solved by using different Networks for every Operator.

Ok, found searched Thread:

But had been yours. So I think there isn´t a working solution for this at all.

I post a sample model.
When the model is running,it look like two operators ,at a same time,load a item on conveyor.In fact,operator2 just always keep loding pose.
Sebastian said One Item can´t be on two Operators same time.so,is there no metheod to accomplish the logic what i described above?

Hi, your model works perfectly. I wouldn't change a thing, it looks good, the movements are good, the time is correct. Why do you want that both operators have a part of the product?

Sebastian is right, an object can only be in 1 object at the time (which is kind of logical isn't it?).
So the only thing that I can think of if you really want that both operators have a piece of a product is splitting the product and giving one to each operator, but why you would want to do that is beyond me??? ((much) More work, more chances on programming errors and on execution errors, and no gain (at least that I can think off))

Your model seems to be working correctly, but you are FRLOADing and FRUNLOADing one item twice, which is messing up the internal counts on the objects.

You also have an awfully inefficient message loop on one of your operators. You don't see the hit in this sample model, but if you have that kind of stuff in a real model, you are going to get a massive speed hit.

You can write code in the OnLoad and OnUnload to do everything you need to do.

Attached is your model with changes made to Operator1's OnReset, OnLoad, and OnUnload to do what you want to do.

I also changed the Request Transport From back to Coordinated Task Sequence Example 2, which is exactly what you are trying to do. The example pick option does it correctly.

thanks a lot for your help!!
And i learn something from your message.
