Forecasting Mean Time To Repair
 
 
Mission:
Provide good estimates to a utility's customers regarding the time to repair a power outage.

Challenge:
Only 7% of the current MTR estimates are within 20 minutes of actual.  Customer desires 50% within 20 minutes of actual.

Solution:
Process Modeler's predictive models of MTR based on a wide variety of factors describing the situation.  Now 32% of the cases are within 20 minutes of actual, a 466% improvement

Objective
A municipal utility wishes to have more accurate estimates of the mean time to repair (MTR) for power outages.  Of course, as soon as the power goes out, people are calling not only to report it, but to find out when it will be restored.  Having a good estimate is an important element of customer service in these situations.

The Methods
Approximately 100 variables in a history of more than 5,000 cases were modeled to estimate MTR based on the situation at hand.  This included the time, place, day of week, equipment involved, crews available and many other factors.  This data was modeled using BioComp's
Process Modeler software to find the most accurate model.

Results
With a quick application of Process Modeler's modeling technologies we were able to increase the estimate accuracy from only 7% of the cases within 20 minutes of actual repair time to 32% of the cases within 20 minutes of actual, a 466% improvement.  The first chart shows the customer's current estimation accuracy (vertical axis is MTR, blue is actual, red is the estimate):
