  The wavelength and rate of the $5p-5s$ transition of W XIV - W XVI ions have
been calculated by the relativistic configuration interaction (RCI) method with
the implementation of Flexible Atomic code (FAC). A reasonable
collisional-radiative model (CRM) has been constructed to simulate the $5p -
5s$ transition spectrum of W XIV - W XVI ions which had been observed in
electron beam ion trap (EBIT) device. The results are in reasonable agreement
with the available experimental and theoretical data, and might be applied to
identify the controversial spectra. The confusion on the assignment of the
ionization stage are solved in the present work.
