Abstract:

To solve the problem of multiple unmanned aerial vehicle (UAV) collaborative logistics task allocation in urban areas, a collaborative logistics task allocation model for multiple UAVs is constructed with the objective function of minimizing economic cost, time penalty and safety risk by comprehensively considering the factors of different UAVs'performance, logistics timeliness and flight reliability. Because of the large scale and high complexity of task allocation, an improved quantum particle swarm optimization algorithm is designed to solve the problem. Firstly, in order to enhance the ergodicity and diversity of particles, particle initialization is carried out by homogenization cascade Logistic mapping. Then, in order to improve the search ability of particles and speed up the running efficiency of the algorithm, particle mutation method based on Gaussian distribution is introduced. Finally, in order to improve the efficiency of the algorithm, adaptive inertia weight method is used to assign different values to each particle. Simulation results show that the constructed model can achieve multi-objective optimization of task allocation. It is close to the reality of UAV logistics distribution in urban areas. Compared with the traditional quantum particle swarm optimization algorithm and the genetic algorithm, the task allocation cost of the improved algorithm is reduced by 5.9% and 6.3% respectively. Furthermore, the parameter weight setting is also analyzed in this paper. When the weight coefficients of the three sub objective functions are 0.225, 0.275 and 0.500 respectively and the population size is 150, the task allocation scheme planned by this algorithm is optimal.
