In order to solve the multi-period and multi-batch relief delivery problem under flood disaster scenarios, a routing model was constructed for collaborative relief delivery of trucks and assault boats by comprehensively considering factors such as the dynamic changes of disaster situations, and the collaborative transportation of trucks and assault boats. The objective of the model was to minimize the total distribution time within each period. A HHA, which combines the improved ant colony algorithm(IACA) with a genetic algorithm(GA), was designed for solving this problem. Compared with the ant colony algorithm and the simulated annealing algorithm, the experimental results show that the HHA provides truck-assault boat collaborative distribution routing solutions under the dynamically changing disaster situations in a relatively short time. The HHA effectively reduces the total distribution time and improves the efficiency of relief delivery. The rationality, feasibility, and effectiveness of the HHA were demonstrated. The number of flooded areas and the number of assault boats have a significant impact on the routing of relief delivery. Emergency logistics decision-making departments should weigh the disaster situation and resource allocation of each flooded area, and dispatch a reasonable number of assault boats to ensure the efficiency of relief delivery.
