In this paper, the establishment of the fuzzy neural network model for logistics distribution center location applied the fuzzy method to the input value of BP algorithm and took the experts' evaluation value as the expected output. At the same time, using the network learning to get the optimized selection and furthermore get a more accurate evaluation to the programs of location.
In order to lower the orientating capability of the DSP satellite, at first the paper analyzes early warning
missile satellite detective system, introduces the jamming mechanism of infrared smoke screen, and a model of jamming
efficiency evaluation of the IR smoke screen against early warning satellite was built from three sides of absorbency of
smoke screen to infrared radiation, dispersion ability and infrared radiation from smoke screen self. At last the correlative
conclusion was got based on the brief depiction of Early-warning Satellite.
