Lot Yield Percent

If lot yield percent is available for the From lot, copy the lot yield percent from the From lot to the resultant lot. This value is assigned to the After To lot. No lot blending rules exist for lot yield percent.

Cumulative lot yield is the accumulated yield of the lot as it moves through all the processes in its cycle. If the cumulative lot yield percent is not available from the operation, the system applies these calculations:

This calculation example is for in-place:

To Before Lot 1: 1000 gallon (CumLotYield = 90%)
Survey Loss on To Lot: 10 gallon (CumLotYield 90% × 99% = 89.1%)
To After Lot 2 (CumLotYield = 89.1%)

This calculation example is for an empty To vessel:

From Before lot 1: 1000 gallon (CumLotYield = 90%)
To Before empty
Survey loss on From Lot: 10 gallon (CumLotYield 90% × 99% = 89.1%)
From After lot 2,200 gallon (CumLotYield = 89.1%)
To After lot 3,770 gallon measured
- Measures infer 20-gallon loss of 790-gallon movement lot
- Movement lot (CumLotYield 89.1% × 97.47 = 86.84%)
To After lot 3 (CumLotYield = 86.84%)

This calculation example is for a Non Empty To Vessel:

From Before Lot 1: 1000 gallon (CumLotYield = 90%)
To Before Lot 2 100 gallon (CumLotYield = 95%)
Survey Loss on From Lot: 10 gallon (CumLotYield 90% * 99% = 89.1%)
From After Lot 3: 200 gallon (CumLotYield = 89.1%)
To After Lot 4 870 gallon measured
- Measures infer 20-gallon loss of 790-gallon movement lot
- Movement Lot (CumLotYield 89.1% × 97.47 = 86.84%)
To After Lot 4 (CumLotYield = (86.84% × 770gal + 95% × 100 gallon) / 870 gallon = 87.78%))

To After Yield = (Volume Moved * Volume Moved Yield + Volume To Before * To Before Yield) / To After Volume
