First,an evaluation index system is established,then D-S evidential combination algorithm is applied to dealing with the evaluating data from many experts.

In view of the more and more complicated urban road net,the Pignistic probability decision rule and the D-S evidence reasoning-based map matching algorithm are adopted to set up the judgment rule for the vehicle position and direction information.

Then, the D-S evidence reasoning-based method and its algorithm for .

Based on the D-S evidence reasoning theory, the differentiating model of aerial targets is been established in this paper.

The article has expatiated the D/S evidential illation s mathematic principle,has discussd D/S eviden- tial illation way s applications on The efficiency evaluation of arm system of air defence missiles,and already has erectd the mathematic model of the efficiency evaluation of arm system of air defence missiles,analysed the math- ematic model with practical cases at the end of the article.

The result of the simulation indicates that the mufti-sensor information amalgamation techniques based on D-S evidential theory is an effective method to realize the TI.

In order to better estimate the fault diagnosis of the hydraulic turbine governing system,the D-S evidential reasoning is used for data fusion with the result of different neural networks.

This thesis puts forward a method of multi-sensors data fusion based on BP network and D-S evidential reasoning, which resolved the incertitude aroused by diagnosis based on single information in fault-diagnosis.

A multi-resources data fusion system of submarine based on D-S evidential reasoning has been structured,and provides a feasible method to solve the problem of BPA distributing.

According to the character of submarine combat information environment,the paper analyzed in detail some problems in the submarine threat evaluation with D-S evidence theory,which are the stealth evaluation,the judgment about attacking or defence.
