Abstract: In order to address the problem of cooperative task assignment for multiple UAVs, a parallel simulation framework was proposed for cooperative task planning based on HLA/RTI simulation through UAV aerodynamic simulations and flight control simulation, which could be more real and effective algorithm validation. The paths were optimized to account for randomization and threats in the environment by modeling the probability of UAV loss. By coupling the failure probabilities of each UAV to the missions of the other UAVs, reality of cooperation was improved significantly. In order to achieve the desired objectives, the stochastic simulation models were used to design cooperation planning to enhance the cooperation between UAVs and improve survival probabilities.
