Analytical modeling of aircraft sortie generation with concurrent maintenance and general service times

The employment effectiveness of a complement of military aircraft is strongly influenced by the sortie generation process. Hackman and Dietz develop an analytical model that captures the interactions between aircraft characteristics and base resources to produce system performance measures such as resource utilization levels and the sortie generation rate. The model employs decomposition techniques to accommodate concurrent service activities and known variability in service times. Useful applications of the model include the identification of bottlenecks, sensitivity analysis, and determination of the distribution of resources required for attainment of a target sortie generation rate.
