  The paper presents a scheduling intelligent system intended for the project
management and for the operation management as well, having integrated a
planner time buffer method combined with the PERT (Programme Evaluation and
Review Technique) method which can drastically short the planned time. The
system also adjusts if necessary the duration for the un-expecting situations
during the evolution of the planner recalculating the probability to reach the
deadline. The system is developed with a friendly graphical interface, which
guide the user during the progress of the project providing warnings and
suggestions for adjusting in real time the planner. Once the scheduling
intelligent system is launched in progress, its functions are combined at the
different levels, depending of the user needs. The base functions of the system
are: planning, diagnosis, supervising and forecast. A real implementation is
showed as a study case, is related to a software development planner.
