The 25th Symposium on Algorithmic Approaches for Transportation Modelling, Optimization, and Systems (ATMOS 2025) will be part of ALGO 2025, which will take place at the Faculty of Physics at the University of Warsaw in Warsaw, Poland. ATMOS is scheduled on 18-19 September 2025.

 

Since 2000, ATMOS brings together researchers and practitioners who are interested in all aspects of algorithmic methods and models for transport optimization. The symposium provides a forum for the exchange and dissemination of new ideas and techniques. The aim of making transportation better gives rise to very complex and large-scale optimization problems requiring innovative solution techniques and ideas from algorithms, mathematical optimization, theoretical computer science, and operations research.

Speaker: Marjan van den Akker, Utrecht University, the Netherlands

Title: A glimpse into OR for airline operations and why this is (not?) public transportation

Abstract: In this talk, we first consider optimization problems in airline operations based on research done in collaboration with KLM Royal Dutch Airlines.  Airline operations are prone to delays and disruptions, due to tight schedules and dependence on various resources. Since the COVID pandemic resource shortages have made the situation worse. In case of disruptions, schedules need to be adjusted in such a way that overall costs as well as impact on passengers are minimized, ideally in near real-time for practical deployment.  Since schedules depend on several resources, we take an integrated viewpoint. We will discuss some problems, such as integrated tail and crew recovery, where we will show that our integrated algorithm outperforms a sequential approach.

Then we move to a more general discussion. Within the operations research community, aviation and public transportation are often treated as distinct areas, with separate conference tracks and even dedicated conferences. This separation suggests that aviation is not considered a form of public transportation. We will challenge this assumption by exploring both similarities and differences in optimization problems in aviation, railways, and public bus transportation.

Authors are invited to submit high-quality manuscripts reporting original unpublished research in the topics related to the symposium. Simultaneous submission to other journals or conferences with published proceedings is not allowed. By submitting a paper the authors acknowledge that in case of acceptance, at least one of the authors must register at ALGO/ATMOS 2025, attend the conference on-site, and present the paper.

 

Submissions must be in the form of a single PDF file prepared according to the author instructions and using the LaTeX OASIcs style file and must be submitted electronically via the EasyChair submission system.

 

ATMOS 2025 accepts two types of submissions, both of which will be reviewed with the same quality standards by the Program Committee.

 

Regular paper submissions: A regular paper submission should clearly motivate the importance of the problem being addressed, discuss prior work and its relationship to the paper, explicitly and precisely state its key contributions, and outline the key technical ideas and methods used to achieve the main results. A regular paper submission should consist of a main body plus an optional and clearly marked appendix. The target length for the main body (excluding the bibliography, the front page(s) (authors, affiliation, keywords, abstract, …)) is 12-15 pages. The total paper, including the bibliography, the front page(s) (authors, affiliation, keywords, abstract, …) and the optional appendix, may not exceed 20 pages. Authors should include all necessary details in their submission so that the Program Committee can judge the correctness, importance and originality of their work. Any material (e.g., proofs or experimental results) omitted (from the main part of 15 pages) due to space limitations can be put into the optional appendix, which will be read at the Program Committee’s discretion. Regular papers will be allotted up to 20 pages in the proceedings.

 

Short paper submissions: A short paper submission may present preliminary results or work-in-progress on a specific topic. Authors should clearly motivate the importance of the problem being addressed, discuss prior work and its relationship to the paper, explicitly and precisely state the paper’s key contributions, and outline the key technical ideas and methods used to achieve the main claims. A short paper submission should have at least 4 and at most 6 pages. Authors should provide sufficient details in their submission so that the Program Committee can judge the correctness, importance and originality of their work. Short papers will be allotted up to 6 pages in the proceedings.
