Analysis of Aircraft Sortie Generation Process Using a Closed Queuing Network Model

Sortie generation rate (SGR) is a key factor of military aircraft´s combat effectiveness. An approximate analytical method is presented to analyzing aircraft sortie generation process by modeling the process as a closed queuing network (CQN). Each station in the CQN provides a kind of service to aircraft. The service time of servers in a same station can be unequal. A modified mean value analysis (MVA) algorithm is used to capture the aircraft´s sortie generation rate and the other performance measures such as queue length and resource utilization. The bottle-neck of the sortie generation rate can be ascertained. The quality of the analytical approximation is demonstrated through comparison with simulation result.
