Abstract
The phenomenological (mathematical) modelling of the observed stellar variability respecting the individuality of each studied variable object comes to be a surprisingly potent instrument for the variable stars research. Particularly, it is effective in solutions of everyday problems of observers engaged in the observation of periodical or nearly periodical types of variable stars and enables to exploit all available observational data as fully as possible. The phenomenological modelling is open for everybody who mastered the basis of PC programming. It enables the reliable determination of times of light curves extrema, the improvement of linear or more complex ephemeris of periodic variables, the study of apsidal motion of binaries and the influence of the third body in the system. At the top, the mathematic modelling applied primarily to original observational data due its transparency and straightforwardness is able to reveal the lacks in the basic treatment of the obtained observational material better than the favoured complex physical modelling. The efficiency of the new approach is documented by several examples.
