| This work develops a aircraft-routing MILP into a scenario-driven study on robustness vs fleet cost. The core is a one-day tail assignment / aircraft routing model with minimum turnaround time and a fleet cap, used first as a feasibility test and then to minimize fleet size and/or connection idle time. The robustness layer is introduced by buffer allocation on flight times and turnarounds using percentiles (e.g., p50-p95) or explicit buffers derived from empirical distributions, consistent with industry practice of block-time reliability targets.
The student will generate scenarios where increasing buffers reduces delay propagation but increases the aircraft required (fixed cost / CapEx) or triggers outsourcing (wet-lease / leasing OPEX). The economic layer extends the routing model by allowing each flight to be operated in-house or outsourced, and by trading additional aircraft (daily equivalent CapEx) against wet-lease premiums. Outputs are "paper-ready" figures: (i) required fleet vs buffer percentile, (ii) idle/slack vs fleet cap, (iii) cost frontier (CapEx vs wet-lease/OPEX) across buffer policies, and (iv) a robustness metric (e.g., probability of breaking next departure, accumulated delay proxy) linked to buffer selection. The thesis is designed so you can steer which scenarios and plots to produce for the paper, while the student executes a controlled, reproducible pipeline. |
