PERT network chart for a seven-month project with five milestones (10 through 50) and six activities (A through F).. The program evaluation and review technique (PERT) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project.
PERT chart for a project with five milestones (10 through 50) and six activities (A through F). The project has two critical paths: activities B and C, or A, D, and F – giving a minimum project time of 7 months with fast tracking. Activity E is sub-critical, and has a float of 1 month.
The main limitations of PERT or CPM that might be addressed by GERT are: there are no alternative paths - all activities have to be performed; there are no loops - it is not possible to repeat activity, next similar activity has to be added; there are no decisions in the diagram - no and, or, xor options which help to choose proper path

In Connecticut’s 2nd Senate District, for example, Republicans decreased their loss margin by some 20 percentage points. But Democrats see promising signs in other areas. In Iowa’s 45th Senate District, where Clinton defeated Trump by about 16 percentage points, Democrat Jim Lykam defeated Mike Gonzales, the GOP candidate, by an almost 50 ...
In probability and statistics, the PERT distributions are a family of continuous probability distributions defined by the minimum (a), most likely (b) and maximum (c) values that a variable can take. It is a transformation of the four-parameter beta distribution with an additional assumption that its expected value is
