González-Ramírez, Rosa GuadalupeMonardes-Concha, Carlos Alberto2026-03-242026-03-242026https://doi.org/10.82218/OPTIMA2025https://repositorio.ucn.cl/handle/20.500.14729/10261We are delighted to gather once again under the auspices of the Chilean Institute of Operations Research (ICHIO) for this biennial meeting, academics, practitioners, and students from Chile and around the world, with a shared passion for advancing the field of Operations Research. Since the first OPTIMA held in 1995, our community has grown remarkably, reflecting the increasing importance of optimization, analytics, and decision-making methods across science, industry, and public policy. Operations Research continues to evolve, driven by challenges that demand innovative models, robust algorithms, and impactful applications. Today, our discipline sits at the intersection of mathematical theory, artificial intelligence, and real-world problem-solving, spanning logistics and supply chain design, health care systems,energy networks, agricultural systems, and beyond. OPTIMA 2025 featured 145 talks whose main topics reflect this rich diversity, spanning stochastic and robust optimization, vehicle routing, network design, analytics and AI, healthcare and energy applications, maritime logistics, and multi-objective optimization, among others.1 Forewords 1.1 Foreword from the Program Committee Chair 1.2 Foreword from the Conference Committee Chair 1.3 Foreword from the ICHIO President 2 Conference Organization 2.1 Organizing Committee 2.2 Program Committee 2.3 ICHIO Board 2.4 ICHIO Congress 3 Conference Schedule 3.1 Monday, December 1st 3.2 Tuesday, December 2nd 3.3 Wednesday, December 3rd 4 Plenary Speakers 4.1 Keynote N°1 4.2 Keynote N°2 4.3 Keynote N°3 4.4 Keynote N°4 5 Accepted Contributions 5.1 Session N°1 5.1.1 Track N°1: Stochastic and Robust Optimization 5.1.2 Track N°2: Operations Research Applications 5.1.3 Track N°3: Combinatorial Optimization 5.1.4 Track N°4: Analytics and Artificial Intelligence 5.2 Session N°2 5.2.1 Track N°1: Vehicle Routing Problem (VRP) 5.2.2 Track N°2: OR Applications in Agriculture and Cities 5.2.3 Track N°3: OR Applications in Supply Chain 5.2.4 Track N°4: Network Design and Location 5.3 Session N°3 5.3.1 Track N°1: Analytics and Artificial Intelligence 5.3.2 Track N°2: Port Logistics 5.3.3 Track N°3: Efficiency and Performance 5.3.4 Track N°4: Network Design and Location 5.4 Session N°4 5.4.1 Track N°1: OR Applications in Agriculture 5.4.2 Track N°2: Scheduling 5.4.3 Track N°3: Waste Management and Recycling 5.4.4 Track N°4: Network Design and Location 5.5 Session N°5 5.5.1 Track N°1: Doctoral Theses 5.5.2 Track N°2: OR Applications in Energy 5.5.3 Track N°3: OR Applications in Health care 5.5.4 Track N°4: Multi-objective Optimization 5.6 Session N°6 5.6.1 Track N°1: Master’s and Bachelor’s Theses 5.6.2 Track N°2: OR Applications in Health care 5.6.3 Track N°3: Network Design and Location 5.6.4 Track N°4: OR Applications and Artificial Intelligence 5.7 Session N°7 5.7.1 Track N°1: OR Applications in Agriculture 5.7.2 Track N°2: Last Mile Logistics 5.7.3 Track N°3: Network Design and Location 5.7.4 Track N°4: Operations Research Applications 5.8 Session N°8 5.8.1 Track N°1: Public Transportation 5.8.2 Track N°2: Stochastic and Robust Optimization 5.8.3 Track N°3: Vehicle Routing Problem (VRP) 5.8.4 Track N°4: OR Applications and Simulation 5.9 Session N°9 5.9.1 Track N°1: Analyticsand Artificial Intelligence 5.9.2 Track N°2: OR Applications in Health care 5.9.3 Track N°3: Vehicle Routing Problem (VRP) 5.10 Session N°10 5.10.1 Track N°1: Last Mile Logistics 5.10.2 Track N°2: Network Design and Location 5.10.3 Track N°3: Analytics and Artificial Intelligence 5.10.4 Track N°4: Operations Research Applications 6 Index of Authors443 páginasenmathematical theoryartificial intelligencehealth care systemsenergy networksagricultural systemsBook
