Lines getting blocked

Creator

Hello everyone,

I am having trouble with lines getting blocked, please see attached picture. The line Accumulation_1 and all the lines downstream of it is getting blocked eventhought there is enough capacity in section_5 to accept the blocked MUs. Section_5 waits till all the MUs exit it to accept new ones. This only happens only once in a while during simulation runs.

 

This problem goes away if i turn accumulation on for section_5, but I do not want to because then I will loose important statistics for the line and distance between the MUs, which is also important. Is there anyway around it without turning the accumulation on?

 

Any help would be much appreciated, thank you,

 

Ram

Let me see if I can.

 

Btw there are no controls, sensors or methods for that line. What do you think is thereason for this?

Thank you,

Ram

maybe capacity or settings of gaps...

Has the predecessor a control?

The line has more capacity than the MUs currently on it. I have a put a minimum gap requiremnt and a cycle time on the line.

No controls are there for the immediate predecessor . The methods seen in the picture are for other lines and the same problem occurs even if i remove them.
