Hi,

We have a factory where we blend chemicals, we have four blenders of various sizes.I’ve created a Work Center and added the four blenders as Resources. I’d like to limit the lot size-in a shop order- each resource can handle. E.g. Resource B can’t handle a shop order of 5000 litres as it can only contain 1.000litres.

 

Thanks for your help.

 

 

 

​@Mbourret is the logic below followed?

  • When Lot Size is 1-1000, use only B.
  • When Lot Size is 1001-5000, use only C.
  • When Lot Size is 5001-6000, use only D.
  • When Lot Size is 6001-8000, use A.

Or is this logic followed?

  • When Lot Size is 1-1000, use B, C, D or A.
  • When Lot Size is 1001-5000, use C, D or A.
  • When Lot Size is 5001-6000, use D or A.
  • When Lot Size is 6001-8000, use A.

​@Mbourret is the logic below followed, or can any blender be used if the lot size is less than its capacity?

  • When Lot Size is 1-1000, use only B.
  • When Lot Size is 1001-5000, use only C.
  • When Lot Size is 5001-6000, use only D.
  • When Lot Size is 6001-8000, use A.

Or would you sometimes use D for an order of 4000 liters when C is occupied?

We try to optimise the lot size based on the size of the blender, so it can occur that we’ll blend a batch below the max capacity of a blender. Though we have minimum quantities we can blend due to the propeller-s and its location in the blender:

  • Blender A- Min 4,000 litres Max 8,000 litres;
  • B: Min 300 litres Max 1,000 litres;
  • C: Min 3,000 Litres Max 5,000 litres;
  • D: Min 2,000 litres Max 6,000 litres.

 

I found the answer for those interested:

  • In Routing; add an Alternate, enter a Min Lot Size Based Qty;
  • For each of these Alternates, enter an Operation and connect it to a Work Centre.

 

 

​@Mbourret take note that for a 5000 liter order, the system will always plan to use alternate A, whereas from your message above you could also use C or D. Manual intervention will be required to flip the order to use alternate C or D when desired.
