The bar graph compares average delay per instance by disruption type across different problem scales. The x-axis represents the disrupted-operation instance scale, labeled as S 1, S 2, M 1, M 2, L 1, L 2, L 3, V L 1, V L 2, and V L 3. The y-axis represents the average delay per instance in minutes, ranging from 0 to 600. The graph is a stacked bar chart with three colors representing different types of delays: light gray for blockage delay, medium gray for engine failure delay, and dark gray for slowdown delay. The bars increase in height from left to right, indicating a trend of increasing delay as the problem scale increases. The highest delay is observed at V L 3, primarily driven by slowdown delay. All values are approximated.Breakdown of average delay per instance by disruption type across problem scale. Slowdown delay is the main contributor overall (52.6% of total delay), followed by engine-failure delay (28.1%) and blockage delay (19.3%)
