Abstract: In this paper, we consider a class of five-dimensional Ricci-flat vacuum solutions, which contain two arbitrary functions mu(t) and nu(t). It is shown that mu(t) can be rewritten as a new arbitrary function f(z) in terms of redshift z and the f(z) can be determined by choosing particular deceleration parameters q(z) which gives early deceleration and late time acceleration. In this way, the 5D cosmological model can be reconstructed and the evolution of the universe can be determined.
