    En gestion de projet, le dépassement des délais ou des coûts est fréquent. Le contrôle de projet ou la mesure de la performance s’avère important. À cet égard, l’outil de mesure de performance disponible est la valeur acquise, laquelle repose sur une planification de base PERT / CPM. Dans un travail récent, Ika (2004), après avoir relevé un certain nombre d’erreurs pouvant être considérées dans la détermination de la valeur acquise, a proposé une méthode pour analyser la valeur acquise dans un contexte d’interdépendance des chemins, dans les conditions d’une distribution bêta de la durée des activités, d’un PERT avec deux estimations et de la méthode stochastique PNET (Probabilistic network evaluation technique). Dans cet article, nous présentons, à l’aide d’un traitement numérique, une procédure rigoureuse pour déterminer la distribution du nombre d’activités complétées sur un chemin ou sur le projet dans son ensemble à un temps t et établir un intervalle de confiance autour de la valeur acquise.
