Coca-Cola has a large fleet of 40,000 Freestyle drink machines at restaurants and movie theaters throughout the US. They are connected to the internet, and every night they upload to their cloud the day’s activity and machine status data for various systems. Each machine has over 10 digitally controlled electronic pumps that dispense flavor ingredients according to customer selection. Pump health data is based solely on machine codes, a symbolic representation of pump behaviors covering a wide range of operating conditions from normal to not-normal.
The Freestyle fleet was experiencing excessive pump failures, which resulted in a degraded customer experience because certain flavors not being available. Service calls for pump replacement were going up. Technicians on-site were unable to diagnose whether it was a pump failure or come other condition. They were replacing many more pumps than necessary.
The Freestyle team engaged DecisionIQ to determine if these machine codes could be used to create diagnostics that would enable on-site field technicians to determine if a pump needed replacement.
