摘要:This paper studies an airline fleet assignment problem under demand uncertainty, with the objective of maximizing expected profit through optimal assignment of aircraft types to flight legs and seat capacities to passenger itineraries. We adopt a data-driven approach that leverages historical demand observations and associated contextual covariates. A key feature of our framework is the treatment of both fleet assignment and price as fixed-design covariates that jointly influence demand, while explicitly accounting for price shift---the discrepancy between estimated prices used in planning and realized prices during operations. We construct a decision-dependent predicted demand distribution leveraging time-series modeling with fixed designs (e.g., fleet assignment and price) and random covariates (e.g., seasonality), and develop a contextual distributionally robust model that hedges against the ambiguity with respect to the predicted demand distribution conditional on the price estimates. We establish finite-sample performance guarantee and asymptotic optimality---impacted by the price shift---of the model solution under several regularity conditions. Computationally, we show the proposed contextual robust airline fleet assignment model can be transformed into a mixed-integer linear program, without inducing additional integers to the assignment decisions. Finally, sufficient numerical experiments with real-life airline operational data demonstrate the effectiveness of our proposed framework.
