摘要

There are three types of S-shaped functions in non-homogeneous Poisson process Software reliability models. The advantages of this shape in this area are demonstrated when many models are proposed based on those functions. This paper evaluates the applicability of the 4th type S-shaped function, the trigonometric functions. However, those functions should be transformed to adapt to the real conditions. The mathematic calculations show that there is a possibility to use the trigonometric functions to introduce a new software reliability model.
