Improvement of D-S theory in an information fusion system

There are many algorithms for multi-sensor information fusion. D-S evidence theory is an useful method to deal with uncertainty problems. The principle of the evidential combination formula is studied, and an improved combination method is put forward according to the shortage of the formula through in-depth analysis. Thus we can not merely make up conflicted evidence like this with different on-line weights, but also carry out adaptive weighting association according to the amount of information that an evidence includes. Some examples have been done to demonstrate that the new method is efficient and can improve the reliability of the combination results.
