Abstract:

Emergency material dispatch is a key link in post-disaster emergency response, and its dispatch efficiency directly affects the rescue effect. Sudden natural disasters are often accompanied by road damage, which seriously restricts the transportation of emergency supplies. In emergency material dispatch, trucks have large carrying capacity and long driving distances. drones do not depend on ground road conditions but are subject to battery and load constraints. The collaboration of the two can achieve complementary advantages. In order to improve the dispatching efficiency of emergency supplies, the post-disaster emergency supplies dispatching strategy of truck-drone collaboration is studied. Taking the shortest time for trucks and drones to complete all material transportation and return to the distribution center as the objective; considering the load and mileage constraints of trucks and drones, road damage and road congestion restrictions, a mixed integer programming model is established. Since the proposed model is an NP-hard problem and combines the advantages of genetic algorithm and dynamic programming algorithm, a new hybrid algorithm (hybrid method based on genetic algorithm and dynamic programming, HGADP) is proposed. Three different scale calculation examples of small, medium and large are designed for the proposed management problem scenario. By comparing the algorithm proposed in this paper with the Gurobi solver and the algorithm proposed in the previous study, the effectiveness of the algorithm proposed in this paper is verified. Through analysis of the calculation example results, it is found that compared with the traditional vehicle transportation model, the truck-drone collaborative transportation model proposed in this article can significantly save material transportation time. Finally, a sensitivity analysis on the drone load capacity and cruising range is conducted, and the impact of parameter changes on the efficiency of emergency material dispatching is analyzed. The emergency material dispatching strategy and is expanded a decision-making basis for emergency material dispatching decisions of emergency management departments is provided in this study.
