Target allocation is an important job in cooperative control of multiple UAVs.The mathematic model for multi-UAV cooperative target assignment was established and a multi-UAV target assignment algorithm based on the satisficing decision-making theory was given.A satisficing set was proposed according to the estimated benefits and costs when each UAV complete the task.A satisfied allocation result was obtained by establishing a reject function and a selection function. Numerical simulations were made under the Matlab environment.The simulation results show that the developed satisficing allocation decision-making algorithm is effective for the cooperative task allocation of the UAVs.
