Abstract:

To solve weight decision of multi mission recovery for a variety of informations, uncertain description , incomplete transmission and little historical record, an index system and decision model of weight decision based on Dempster Shafer theory are put forward. Various types of quantitative and qualitative decision information are translated into basic probability assignment in the same framework． According to each weight of information, basic weight effective values are assorted and integrated layer by layer through Dempster Shafer theory. And a quantitative method based on non empty information is given. Simulation results show the effectiveness of the approach.
