New arXiv paper frames end‑of‑life aircraft as a large scheduling problem

A new study posted on arXiv (arXiv:2605.23592) tackles a practical — and surprisingly urgent — operations research challenge: how to schedule the disassembly of aircraft that have reached their end of life. The paper, titled "Solving the Aircraft Disassembly Scheduling Problem," frames dismantling as a large-scale scheduling problem whose efficient solution is critical to turning a thin-margin sustainability task into a viable part of airlines’ business models. The preprint is available at https://arxiv.org/abs/2605.23592.

The operational challenge

Dismantling an airframe is not a single task but a tightly constrained sequence of operations: hazardous-material removal, engine and avionics extractions, inventorying salvageable parts, and recycler workflows. It has been reported that margins on aircraft recycling are small, so sequencing, resource allocation and timing matter. The authors model these interdependent jobs at scale and propose algorithmic approaches to reduce idle time and increase throughput — in other words, to make disassembly pay its way rather than become a loss center.

Why this matters beyond the hanger

This is not just an academic exercise. Airlines worldwide are retiring fleets as they modernize for fuel efficiency and emissions targets, while a global market for used parts and recycled materials grows. Geopolitics complicates the picture: export controls, sanctions and shifting trade policy can change where parts can be sold and which workshops can accept components, altering the economics of any scheduling solution. Can better scheduling tilt the balance toward a circular, lower‑carbon aircraft economy? The authors argue it can — and the paper provides a practical starting point for industry groups and regulators to test those claims.
