Flight Recovery Method of Regional Multiairport Based on Risk Control Model

Table 10

Comparison of efficient solutions between RCM and TRM.

Optimization objective	Risk control method (RCM)		Traditional recovery method (TRM)
	Optimal delay time	Optimal risk probability	Optimal delay time	Optimal risk probability
Delay time	3350.0	3742.5	3313.2	3895.8
Gap	+1.11%	−3.94%
Risk probability	9.56	8.46	9.87	8.66
Gap	−3.14%	−2.34%

Note. “Gap” refers to the gap between the optimal efficient solutions obtained by RCM and TRM. For example, the “delay time gap” between RCM and TRM in the effective solution of the shortest delay time is calculated as follows: (3350 − 3313.2)/3350  100% = +1.11%.
