This thesis designs, develops, and tests three models which comprise the dynamic air route selection package for use in the Future Theater-Level Model (FTLM). Model I computes the portion of each square air grid covered by a selected characteristic radius of each ground unit. Model II uses Dynamic Programming and priority queue techniques to select ingress (and separate) egress routes from flight group air rendezvous points to a designated air grid which may be a target, reconnaissance area, or orbit location. Model III simultaneously selects a target from several candidates, selects a route and determines the implications of various escort aircraft levels in an optimal fashion, based on the measure of effectiveness (MOE) of minimizing the combined value of three factors (tactical difficulty, travel distance/time, and target priority). Comparison of different ground situations and weight sets associated with these three factors are presented to illustrate the flexibility and use of these models.
