Problem Statement
Arrival flow variance causes
Unbalanced Utilization of Airline/Airport Resources.
- Reduced Runway Throughput
- Excess Airborne Delay (Holding Pattern)
- Excess Fuel burn / Carbon Emissions
Production Variance
What is Production Variance
- Extra wide bell curve of actual Arrivals around the Schedule.
Symptoms of High Variance
- Underutilization of assets, over utilization of
consumables, i.e., higher fuel burn
- Ever increasing block time
- Decreased product quality, no product differentiation
- Less satisfied customers, lower customer expectations
- Less system throughput/productivity
- Increased production of green house gasses (CO2/NOX emissions)
- Randomness and chaos, collapse of the static processes
- Just in case Operations, numerous last minute changes
Sub-optimal and unbalanced system
