I have a conveyor sorter and would like to calculate OEE.
Cartons are inducted, scanned, and sorted.
There is no planned downtime during a shift.
So I will consider total counts by shift for everything.
There are several lanes the cartons are diverted to, but I am only considering the total right now to fiqure out the sorter’s efficiency.
If the lane is full or jammed, or barcodes cannot be read, the cartons are recirculated to be re inducted.
I have counts for inducted cartons, recirculated cartons, diverted cartons, and sorter runtime.
So far I think I should use:
Availability = runtime/shift time
Performance= (infeed/runtime) / OEE std rate
so, there isn’t a OEE std rate for shipping cartons of which are all various sizes so there really cannot be a standard throughput here.
but, if I can use infeed = diverted + recirculation, and use the maximum value of diverts I have seen in my sample size as std rate, this might be close.
I might as well just disregard this, if I calculate performance like I mentioned.
I would appreciate any feedback, and alternatives.
