Modeling Multioperator Multi-UAV Operator Attention Allocation Problem Based on Maximizing the Global Reward

This paper focuses on the attention allocation problem (AAP) in modeling multioperator multi-UAV (MOMU), with the operator model and task properties taken into consideration. The model of MOMU operator AAP based on maximizing the global reward is established and used to allocate tasks to all operators as well as set work time and rest time to each task simultaneously for operators. The proposed model is validated in Matlab simulation environment, using the immune algorithm and dynamic programming algorithm to evaluate the performance of the model in terms of the reward value with regard to the work time, rest time, and task allocation. The result shows that the total reward of the proposed model is larger than the one obtained from previously published methods using local maximization and the total reward of our method has an exponent-like relation with the task arrival rate. The proposed model can improve the operators' task processing efficiency in the MOMU command and control scenarios.
