A new metaheuristic named ACO-LNS is developed to increase security in the CIT sector. The ACO-LNS combines the ant colony optimization with a VND heuristic. The ACO-LNS uses an effective large neighbourhood search heuristic. A set of benchmark instances for the RCTVRP is proposed and made publicly available. The ACO-LNS outperforms the existing algorithms for the RCTVRP.
