StayTime and Process Time

Hi,

I am trying to simulate stamping line and it consist of 5 stamping machines strike rate 530strikes/hour so it means stamping proces should be 6.8seconds but staytime is like 9.5sec. I suppose its because of robot moving item in and out. In reality the whole process takes 6.8sec because as the die sets is going up robot already picking the part. I just wanna ask if there is some solutions to this because all i came up is to combine loading and procesing time manualy to get 6.8 sec stamping time.

There is the model current_state.fsm

Thanks for help

Software Version:

FlexSim 22.2.0

processtime staytime 3dmodel

current-state.fsm (253.9 KiB)

@Juraj, it is a model you are building. It imitates reality. What if you omit any robot action at all and you say this process is done in a black box. Timing is correct, but visualization is not. Please think about what really does matter to get to results. A nice look or correct timing?

You are right correct timing is more important but i also wanted to show utilizations of robots.

Robot visualization is a real problem. It depends on knowledge what a robot does in reality. A robot path is a result of kinetic, drive power and move programming. There are some tools to simulate robot cycle times by vendors. Robotstudio, ACE, SIMATIC, KUKA.SIM. Their focus is a simulation of a single closed process rather than a variation of statistical input on production results. See a robot interaction in FlexSim as an animation. Lastly it is a black box showing a video. You need a library object designed by a robot manufacturer to get reliable results in FlexSim.
