MAV/UAV cooperative operations are becoming a research hot spot in various countries.In response to current demand for effectiveness evaluation of cooperative operationsthis paper discusses a method for evaluating the effectiveness of MAV/UAV cooperative operations based on Hopfield network.By analyzing the typical models of MAV/UAV cooperative operationsand integrating the content of “Observation-Orientation-Decision-Action (OODA)” mission loopthe index system for effectiveness evaluation of MAV/UAV cooperative operations is established.The evaluation data obtained by Extensional Analytical Hierarchy Process (EAHP) and the fuzzy evaluation method is taken as the reference standard of Discrete Hopfield Neural Network (DHNN).Based on the associative memory function of DHNNan effectiveness evaluation model for MAV/UAV cooperative operations is designed.Example analysis and simulation verification are conducted.The simulation results show that this method can realize an objective and effective evaluation of the effectiveness of MAV/UAV cooperative operations.
