Unexplained Seasonal Variance
Micro-stop rates doubled from 2-3/day in winter to 5-6/day in summer. This seasonal pattern was observed but attributed to 'summer heat issues'—vague and unaddressed.
What Became Visible
Detailed seasonal micro-stop + environmental data analysis revealed: Summer (25-30°C) sensor performance degraded 15-20%, causing intermittent signal loss. Winter (5-10°C) sensor performance was stable. The sensor specifications required 15-25°C operating temperature for optimal performance.
Thermal Management Strategy
Summer cooling system implemented to maintain sensor ambient temperature within optimal range. This prevented the thermal-drift-induced sensor failures.
How it worked: Environmental monitoring + micro-stop correlation revealed the thermal root cause. Thermal management eliminated seasonal variance.
Results
winter and summer
from seasonal elimination
Seasonal micro-stop variance indicates environmental sensitivity. Addressing the environmental cause eliminates seasonal performance fluctuation.
Operational Reality
The facility thought it was accepting 'summer challenges.' Root-cause analysis revealed a solvable thermal management problem.
