I have data of 5 sensors(speed,temp,rotations etc), based on that I determine the value of remaining life of part. I have historical data of part A till it’s life become zero.

Now I have another part B (type same as part A) and I need to determine remaining life ofpart B based on current value coming from 5 sensons and considering the historical data of Part A.

Please suggest how should I determine remaining life of part B, which PAL algorithm should I use.
