1st CfP: Multi-Objective Decision Making Workshop (MODeM 2025) at ECAI 2025

-------------------------------------------------------------------------------------------------------------

TLDR

• Following on from successful previous editions that were held virtually in 2021 and in person at ECAI 2023 and ECAI 2024, the Multi-Objective Decision Making 2025 (MODeM 2025) workshop will be held in person again this year at ECAI 2025, on 25/26 October in Bologna, Italy.
• MODeM 2025 covers all aspects of multi-objective/multi-criteria/multi-attribute decision making in relation to intelligent systems and autonomous agents
• Further details are available on the workshop website: https://modem2025.vub.ac.be/
• MODeM 2025 Workshop paper deadline: 15 July 2025 (23:59 AoE)

-------------------------------------------------------------------------------------------------------------

Explicitly modelling multiple objectives can be essential for decision support, explainability, and human-AI alignment. As such, there has been a growing awareness of the need for automated and assistive decision making systems to move beyond single-objective formulations when dealing with complex real-world issues, which invariably involve multiple competing objectives. In this workshop, we aim to provide a platform for original research in multi-objective decision making using AI. 

The workshop targets high-quality original papers covering all aspects of multi-objective decision making, including, but not limited to, the list of topics below.  

Topics

The following is a non-exhaustive list of topics that we would like to cover in the workshop:

• Multi-objective/multi-criteria/multi-attribute decision making
• Multi-objective reinforcement learning
• Multi-objective planning and scheduling
• Multi-objective multi-agent decision making
• Multi-objective game theory
• Multi-objective/multi-criteria/multi-attribute utility theory
• Preference elicitation for MODeM
• Social choice and MODeM
• Multi-objective decision support systems
• Multi-objective metaheuristic optimisation (e.g. evolutionary algorithms) for autonomous agents and multi-agent systems
• Multi-objectivisation
• Human-AI alignment through multi-objective modelling
• Ethical AI through multi-objective modelling
• Explainable AI through multi-objective modelling
• Interactive systems for MODeM
• Applications of MODeM
• Interdisciplinary work (MODeM research that relates to other fields)
• New benchmark problems for MODeM

Important Dates

• Submissions deadline: 15 July 2025 (23:59 AoE)
• Notification of acceptance: 15 August 2025
• Camera-ready copies: 15 September 2025 
• Workshop: 25 or 26 October 2025 (TBA)

Submission details

Papers should be formatted according to the ECAI 2025 guidelines, and should be a maximum of 7 pages in length (with additional pages containing references only). Shorter papers (up to 5 pages) reporting preliminary results and work-in-progress are also welcome. Submissions should report original work that has not previously been published elsewhere.  Finally, we also welcome summaries of recently published journal papers in the form of a 2-page abstract.

All submissions will be peer-reviewed (double-blind). Accepted work will be allocated time for oral and/or poster presentation during the workshop.

Papers can be submitted through EasyChair: https://easychair.org/conferences?conf=modem2025
