Patent attributes
A computer-implemented simulation method for analyzing schedule risk in a graphical schedule that includes (a) providing a base schedule that has graphical schedule objects including activities that are connected in a logic network by logic ties, the schedule culminating in a completion milestone, (b) sampling from probability distributions representing uncertainties in the durations of the activities to simulate activity durations from start dates to finish dates, (c) modifying the start date of one of the activities as a function of float or drift of the activity, and (d) using the logic ties, the sampled activity durations, and the modified start date to determine an output representing a simulated occurrence of the base schedule culminating in the completion milestone.
