BPA function combination based on D-S data fusion.

Step 1: Collect the vibration and temperature signal

Step 2: Calculate the absolute correlation matrix of the selected features

Step 3: Find the feature which has the highest correlation coefficient among these features.

Step 4: Remove the interference terms of the feature signals

Step 5: Calculate each BPA function based on acceleration and temperature data

Step 6: Calculate the RUL prediction based on acceleration and temperature fusion data and repeat step 5 to step 6 until a_k equals the threshold value

Step 7: Calculate the RUL prediction
