Steam Plant Forecasting
The production manager of a large steam plant wishes to forecast monthly steam usage for that facility, based on operating plans and anticipated weather behavior. The MLR input data below shows observations taken at intervals from the steam plant. The measured variables are:
X1: Real fatty acid in storage per month (in pounds) X2: Crude glycerin produced (in pounds) X3: Average wind velocity (mph) X4: Calendar days per month X5: Operating days per month X6: Days below 32 degrees F X7: Average atmospheric temperature (in degrees F) X8: Average wind velocity squared X9: Number of start-ups Y: Monthly use of steam (in pounds)
