Comparison of multiobjective optimization results.

Optimization objective	Risk control method (RCM)			Traditional recovery method (TRM)
	FCFS	Optimal delay time	Optimal risk probability	FCFS	Optimal delay time	Optimal risk probability
Delay time gap	7386	3256	3665	7299	3251	3874
		−55.79%	−50.37%		−55.46%	−46.92%
Risk probability gap	8.91	9.67	8.49	9.16	9.90	8.71
		8.53%	−4.71%		8.08%	−4.91%

Note. “Gap” refers to the gap between the optimal efficient solution obtained by RCM or TRM and the scheme obtained by FCFS. For example, the “delay time gap” between the effective solution with the shortest delay obtained by RCM and the FCFS scheme is calculated as follows: (3256 − 7386)/7386  100% = −55.79%.
