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.
