Abstract
Combinatorial optimization problems involve identifying the best solution from a wide set of alternatives; these often arise in logistics, scheduling, and resource allocation. These problems, such as the Traveling Salesman Problem (TSP) and the Multi-Depot Vehicle Routing Problem (MDVRP), are generally NP-hard, with solution spaces that increase exponentially, making brute-force methods impractical. We address a specific application of the MDVRP: the Electricity Technician Dispatch Problem (ETDP), which involves planning and optimizing technician routes for maintenance services to customers at various geographical locations while satisfying specific constraints and objectives. We focus on a variant of the ETDP that optimizes multiple objectives, including economic, environmental, and social. Economic objectives aim to reduce operational costs, such as fuel costs and technician wages. Environmental objectives focus on sustainability, for example, by minimizing gas emissions. Social objectives include fairness of workload and customer satisfaction. We will explore the ETDP problem in single- and multi-objective contexts and solve it using nature-inspired techniques.
Electric vehicles (EVs) are crucial for mitigating greenhouse gas emissions in urban transportation. However, their integration requires efficient charging infrastructure and allocation strategies. In this paper, five heuristic algorithms were developed to allocate EVs to urban charging stations. This allocation proces...

Efficient transportation planning requires balancing economic performance, operational efficiency, and environmental responsibility. In real-life transportation systems, transportation planner frequently need to include more than one conflicting factors like minimizing transportation cost, minimizing transportation tim...

Urban battery swapping station (BSS) planning is difficult because site opening, service-module allocation, user assignment, battery degradation pressure, travel burden, and congestion are tightly coupled. A plan that minimizes investment alone may create long queues, whereas a plan that only reduces waiting can overbu...
