Chart Or Publication; Human Factors
We were cleared to a point on the approach plate that did not have the same name as the FMS routing causing confusion as to where we were cleared to.We did not have an event as such; but the arrival procedures for the VOR DME is confusing and maybe someone can make it better. Our routing takes us on the FMS to: DXXXX; DXXX; CFXX; FF16.  DXXX which = IAF D15.0 on the approach plate.  DXXX = IF D11.0 on the approach plate.  CFXX = D9.0 on the approach plate.  FF16 which is correct on the approach plate as FF16.  Why can't the approach plate and the FMS routing fixes be the same for these points?  The same problem is on the departure plates.
A B737-800 Captain expressed confusion with respect to the FMS database identifiers versus the approach chart identifiers of the same locations of fixes; on a tailored VOR/DME approach.
