Title: Assessing the benefit of Robust Route assignment in case of air congestion

Abstract: The exponential growth of Waste Electrical and Electronic Equipment (WEEE) poses critical logistical and en vironmental challenges. Efficient collection routing is essential to optimize economic return and mitigate environmental harm. This paper presents a simulation-based optimization framework for WEEE collection, formulated as a bi-objective capacitated vehicle routing problem with heterogeneous pickups (Bi-CVRP HP). The model simultaneously maximizes collection revenue and minimizes operational costs, under realistic constraints including vehicle capacity, service times, and time windows. Multiple heuristic solution strategies—Greedy, Clarke & Wright Savings, and Genetic Algorithms—are proposed and evaluated. Computational experiments on a realistic dataset confirm the effectiveness of the model and elucidate trade-offs between profit, computational effort, and resource usage.

Bio: Dr. Ludovica Adacher is a university researcher in the scientific-disciplinary sector ING-INF/04 – Systems and Automation at the Department of Civil, Computer Science and Aeronautical Technologies Engineering of Roma Tre University. She is actively involved in both teaching and research, focusing her work on the modeling and optimization of complex systems, particularly in the fields of transportation, logistics, automation, and discrete-event systems. She teaches undergraduate and graduate courses in “Analisi dei Sistemi ad Eventi” (Analysis of Event-Driven Systems) and “Simulazione di Processi Industriali e Logistici” (Simulation of Industrial and Logistic Processes). These courses are part of the Computer Engineering and Artificial Intelligence curriculum, as well as the Management and Automation Master's program. Her teaching consistently integrates theoretical foundations with applied methodologies, equipping students with tools to model, simulate, and optimize real-world processes. Dr. Adacher's research is notable for its depth and interdisciplinary scope. She has authored or co-authored around 60 publications, addressing topics such as urban traffic control, electric vehicle infrastructure, airport ground operations, supply chain management, and congestion resolution. Notable among her recent works is a 2023 paper on decentralized electric vehicle charging station assignment using Lagrangian relaxation methods, reflecting her ongoing interest in smart and sustainable mobility solutions. Other prominent studies include analyses of cell transmission model extensions for urban networks, traffic light synchronization, and air traffic rerouting under congestion scenarios. In addition to her academic responsibilities, Dr. Adacher serves as the Erasmus coordinator for Computer Engineering at Roma Tre, helping to manage international student exchanges and promote academic mobility within the European educational framework. Dr. Adacher’s work bridges theoretical research and practical applications, with a strong emphasis on systems optimization in complex, real-world environments—making her a key figure in the field of automation and intelligent transportation systems at Roma Tre University.
