Concurrent Aircraft Design and Airline Network Design Incorporating Passenger Demand Models

TLDR
A unifying conceptual framework that builds upon previous works is proposed to concurrently design aircraft and the operational network by incorporating established passenger demand models and reflexivity of demand.
Abstract
Conceptual aircraft design and the network routes that they trave l on are inextricably linked to passenger driven demand. Decisions made in the acquisition and subsequent allocation of aircraft assets to serve chosen links translate to latent passenger observations of ticket pricing and routes served between origin -destination (OD) pairs. It is proposed that such latency gives rise to a reflexive behavior in demand as subsequent operational decisions give rise to reflexive passenger demand conditions. In this paper, a unifying conceptual framework that builds upon previous works is proposed to concurrently design aircraft and the operational network by incorporating established passenger demand models . A conceptual scenario formulated and solved to exhibit the methodology employed and reflexivity of demand.

An Approximate Dynamic Programming Approach to Aircraft Allocation Incorporating Passenger Demand Models

TL;DR: This paper presents an approach in which an allocation problem represents how an airline offers service to meet passenger demand at a given time step, and uses concepts from dynamic programming to make allocation decisions that could maximize or minimize an airline objective function over a finite time horizon.

Variable Resource Allocation Using Multidisciplinary Optimization: Initial Investigations for System of Systems

TL;DR: A simple problem using an airline wishing to investigate how a new, yet-to-be-designed aircraft will impact the fleet operating costs provides an example of this type of problem, and the MDOmotivated decomposition approach appears to have promise for the allocation of variable resources challenge presented by many SoS design problems.
