An intelligent optimization approach for waste collection with dynamic disposal trips

This paper investigates a waste collection problem with the consideration of dynamic disposal trips. A hybrid artificial bee colony (ABC)-based approach is developed to handle this problem. We hybrid the ABC algorithm with the variable neighborhood descent algorithm to generate the better optimum-seeking performance, and propose heuristic procedures to choose disposal trip dynamically and calculate the carbon emission in waste collection process. The effectiveness of the proposed algorithm is validated by numerical experiments. The experimental results show that (1) the proposed hybrid ABC algorithm can solve the investigated problem effectively; (2) the algorithm exhibits better optimum-seeking performance than several traditional metaheuristics; (3) dynamic disposal trips should be considered in practice because it reduces the carbon emission at most 7.29% for investigated instances.
