This book gathers a selection of peer-reviewed papers presented at the Seventh International Conference of the Tunisian Operations Research Society (IC_TORS'25) which was held in Sousse, Tunisia from 11th to 13th April 2025. It was sponsored by the Association of European Operational Research Societies (EURO), the International Federation of Operational Research Societies (IFORS), and INFORMS Bahrain International Group.

The book explores research issues in operational research and decision aid, highlighting recent theoretical advancements in areas such as linear, nonlinear, integer, stochastic, multilevel, and multi-objective optimization, as well as business analytics, simulation, decision theory, and multi-criteria decision aid. It also presents real-world applications across various sectors, including Industry 4.0, renewable energy, agriculture, green logistics and transportation, healthcare, water resource management, and sustainable, resilient supply chains.
