Robots won't work at the same time

Hi everyone,

 

in the attached model the robot/s take parts from the source,
moves them to one of the Type A machines, then moves the parts
to one of the machines from Type B, and finally moves the part to
the line, which takes them to the drain (the throughput is shown via Display).

the robot's logic is based on the stations from which the part came from

(if it came from the source, it is moved to the flow control for Type A machine,
if it came from a Type A machine it is moved to a Type B machine, etc.).

 

I've built the attached model with 2 frames -

One_Robot: contains one robot that moves the parts between stations.

Two_Robots: contains two robots that move the parts between stations.

 

the problem is that i get the same throughput in both frames because the two
robots seem to wait for each other or for an event (like the MU moving through
the entire line) before moving to the next task.

 

any idea how this could be resolved in a way that demonstrates the throughput
difference (the added advantage) of having two robots instead of one?

 

Thanks in advance,

Amir

Hi Amir,

 

it seems that the robot is not the bottleneck. So one robot is just enough.

 

If you look at the blocked time of the stations you see that the percentage is very low.

So actually no station is ever waiting for the robot.

 

You just proved that the invest in a second robot is not worth the money :-)
