This paper investigates a case of a restaurant which provides the delivery of Thai barbecue (BBQ) food to customers around Nonthaburi Province, Thailand. Currently, the delivery planning is done by using personal experience which is inefficient. In order to solve this case study which was identified as a vehicle routing problem, with backhauls, a coral reef optimization algorithm is modified and compared to the real decisions of the planner who has motivated this problem. The results show that the proposed algorithm is competitive with the planner decision. The total delivery distances are also decreased by 17.97%. These results suggest that coral reef optimization algorithms may be useful to many different restaurant delivery services.
