1.Functional Description
1.1Purpose
This function will generate the forecast numbers for Method 4, Moving Average, if the processing
option is set to do so. It will also decide if this method is the Best Fit forecast.
1.2Setup Notes and Prerequisites
1.3Special Logic
2.Technical Specifications
Method 4 - Simulate Moving Average
If NumberOfBuckets is less than MonthsBestFit + MoveAvgNoMonths
Move '1' to DataError
End Function
End
Subtract MonthsBestFit from LastBucketPosition to get $X
$SIM = 0
$TOT = 0
Do MonthsBestFit times
Subtract MoveAvgNoMonths - 1 from $X
$AVG = 0
Do MoveAvgNoMonths times
If ForecastAmounts is not set to '1'
Add PtrToActualSales,$X to $AVG
Else
Add PtrToActualAmounts,$X to $AVG
Add 1 to $X
End
Divide $AVG by MoveAvgNoMonths
If MeanAbsoluteDeviation is not equal to 1
Add $AVG to $SIM
Else
If ForecastAmounts is not set to '1'
Subtract $AVG from PtrToActualSales,$X to get $DIFF
Else
Subtract $AVG from PtrToActualAmounts,$X to get $DIFF
End
Add the absolute value of $DIFF to $TOT
End
End
If MeanAbsoluteDeviation is not equal to '1'
If ForecastAmounts is not equal to 1
Divide $SIM by QtyBestFit to get MethodYield
Else
Divide $SIM by AmtBestFit to get MethodYield
End
Decide if this method is the Best Fit Method
If MethodYield is greater than 1
Subtract 1 from MethodYield to get $SPER
Else
Subtract MethodYield from 1 to get $SPER
End
If $SPER is less than BestFit
Move $SPER to BestFit
Move 4 to Method
End
Else
Divide $TOT by MonthsBestFit to get MethodYield
Decide if this method is the Best Fit Method
If MethodYield is greater than BestFit
Move MethodYield to BestFit
Move 4 to Method
End
End
