Steepmanagement: Fuzzy Math of Snowmaking
Brian Tito Alex
Data Analyst / Owner, Snowmaking Efficiency, LLC
One thing of the many I have learned over a long life is that their are people out there who know so much more than I do, and using or even copying their teachings and ideas is not bad. So, I am sharing Tito’s thinking and emphasis on metrics or KPI’s.
As Tito says, losing that lost snow production not only means less snow but an increase in cost. Take advantage of this input. Using input such as this doesn’t make you less of a snowmaker, it makes you a better snowmaker. Who doesn’t want to be a better snowmaker?
"Right now we are seeing very good early season temperatures for snowmaking. It is true that gallons to date are far ahead of any other year, although this measurement does not quantify that snowmaking is operating at peak efficiency. The reason is because GPM and calendar days are time based, not temperature based.
For example, while 30 million gallons of water flow is a great start, temperature based metrics can show that flows should have been 36 million, or 20% more snow. And every manger wants more snow sooner.
These KPI’s come from bottom-up data collection and reporting. An example for 12 hours of snowmaking is shown in the link. http://snowmakingefficiency.com/the-future-of-snowmaking-asset-utilization/
The chart in this second link also comes from temperature based metrics. The gap between the lines is lost snow production and shows the increase in cost/acre foot of snow. http://snowmakingefficiency.com/id-measure-optimal-snow-production/
Best Practices use temperature based metrics, not time based totals and averages.
