Approximate mean value analysis of airport sortie generation process on condition aircrafts launch in batches

Sortie generation rate (SGR) which means sustainable number of airport launches per period is a key factor of military aircraft´s combat effectiveness. An approximate mean value analysis (MVA) method is presented to evaluate airport sortie generation process which is modeled as a closed queuing network (CQN). N aircrafts circle in the process and each batch which is to launch contains N_b readied aircrafts. The approximate MVA algorithm is used to capture the aircraft´s sortie generation rate and the other performance measures such as queue length in each station and resource utilization of servers. The bottle-neck of the airport sortie generation process can be found out through the utilization. The quality of the analytical approximation is demonstrated through comparison with simulation results.
