Abstract:

Aiming at the problem of strong subjectivity and high complexity in the effectiveness evaluation of space-based information support system, a projection gradient neural network-based effectiveness evaluation method for space-based information support system is proposed. Firstly, based on the Department of Defense Architecture Framework (DoDAF) optical products and observation-orientation-decision-action (OODA) loop are used to sort out the system operational process, and then the evaluation index system is established, and the data samples for effectiveness evaluation are generated based on the discrete-event simulation. Then, the effectiveness evaluation agent model is constructed based on the Rosen-back propagation (BP) neural network, and the restriction of the weight parameter is used to solve the problem that the evaluation model is difficult to be interpreted under the efficiency-type indexes. Finally, a validation test of the evaluation model is conducted on the simulation samples, and the results show that the proposed method can improve the computational performance by more than 50% compared with the traditional BP neural network in the effectiveness evaluation of space-based information support systems, which can provide technical support for the evaluation of the effectiveness of space-based information support systems.
