We consider a three-parameter PASEP model on $N$ sites. A closed formula for the partition function was obtained analytically by Blythe et al. We give a new formula which generalizes the one of Blythe et al, and is proved in two combinatorial ways. Moreover the first proof can be adapted to give the moments of Al-Salam-Chihara polynomials.

Par ailleurs la première preuve peut être adaptée de sorte à obtenir les moments des polynômes d'Al-Salam-Chihara.
