Randomized trial optimizes waste collection routes using electric vehicles, suggesting an environmentally friendly approach.

This research aims to develop a model that optimizes waste collection logistics using electric vehicle fleets.
Proposed a model for optimal depot locations and vehicle routing for waste collection.
Applied the ϵ-constraint method for small instances and NSGA-II and MOPSO for larger instances.
Conducted a case study in Southern Tehran to validate the model's practical applicability.
Both NSGA-II and MOPSO effectively optimized costs and travel times without significant differences.
NSGA-II showed advantages in computational efficiency and solution quantity.
MOPSO excelled in convergence quality, providing near-accurate Pareto fronts.

Feyzli et al. (2026) studied this question.
