Non Accumulating Conveyor

The conveyor is non-accumulating and has 6 stations having different processing time.

All timing is in second.

The decision point represents buffer inventory between stations( for representation only).

Process time of stations station 1= 10, station2= 20, station3=10, station4=30, station5=5, station6=100


Let's assume after some time parts sit on 3 stations( station1, station2 and station 3) together so, before a part moves to next station (i.e. station 4), it should take total process time of 20 sec ( which is maximum process time among three stations) instead it is taking 40sec( i.e summation of process time of 3 stations).


what is the problem here or is there any way so that it takes 20 sec ( which is maximum process time among 3 stations ) or In other words as parts arrive at stations, processing of parts should start together instead here stations are processing parts separately.

Please find the attached model. Thanks in advance.

@swami P2,

Ironically, this question is almost identical to this question. Maybe you guys should collaborate. :)

Unfortunately, stations are designed to process one at a time and they don't automatically bundle together and process for the maximum process time of all the stations. However, you can use Process Flow instead to accomplish what you've described.

At each Station, you can still calculate a Process Time, but instead of adding it as the Processing Time value, add it as a label to the item and push the item to a list. Then, in Process Flow, pull all the items at the stations from the list, calculate which of the processing times is longest, and delay the conveyor for that amount of time. That way, you're simulating the process correctly. Let me know what questions you have. In the meantime, I will work on an example model.

Here's a working model with Process Flow added.
