1Productivity
If flight delays are extended to optimize resource utilization, then equipment and crew management efficiency is improved, but passenger inconvenience and adverse effects increase
Solution Approach 1:
The system dynamically adjusts delay parameters by computing probability curves that show the relationship between delay length and number of adversely affected passengers. The optimization model selects specific delay lengths (e.g., adjusting from original delay to optimized delay) that balance resource utilization with passenger impact, transforming fixed delay decisions into flexible parameter optimization.
Solution Approach 2:
The system implements continuous feedback loops by monitoring real-time flight data, computing cascade boundaries, and evaluating the impact of delay adjustments. The optimization model uses feedback from probability curves and cascade projections to iteratively refine delay decisions, ensuring that resource management improvements do not excessively increase passenger inconvenience.
2Object-affected harmful factors
If real-time delay optimization is implemented across multiple airports, then passenger disruptions are reduced, but computational complexity and system resources increase
Solution Approach 1:
The system segments the air-traffic optimization problem into manageable components: individual airport analyses, separate probability curve computations for each airport, and modular cascade boundary projections. This segmentation allows the complex multi-airport optimization to be broken down into independent computational units that can be processed separately and aggregated, reducing overall computational complexity.
Solution Approach 2:
The system performs preliminary computations of probability curves and cascade boundaries before final delay decisions are made. By pre-computing these analytical tools and storing them for quick reference, the system avoids performing complex calculations in real-time when delays need to be adjusted, thereby reducing computational burden during critical decision-making moments.
3Measurement precision
If cascade boundary projection is used to predict delay impacts, then accuracy in minimizing adversely affected passengers is improved, but measurement and computation difficulty increase
Solution Approach 1:
The system introduces probability curves as intermediary computational tools that simplify the relationship between delay length and passenger impact. Instead of directly computing complex cascade effects across multiple airports, the probability curves serve as intermediaries that translate delay parameters into expected passenger impact metrics, making the measurement process more manageable while maintaining accuracy.

AI summary
An optimization model is selected to reduce a number of passengers adversely affected by a delay of an aircraft. A cascade boundary is determined for a length of the delay, which projects the delay at the plurality of airports. Using the optimization model, a probability curve is computed at an airport from the plurality of airports, which outputs a second length of the delay experienced at the airport responsive to the cascade boundary projecting the delay on the airport. The length is adjusted in the optimization model such that a count of passengers adversely affected by the delay at the airport at the elapse of the second length is minimized. A target system is caused to configure the aircraft to be delayed by the adjusted length.
