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 .
[2] [3] The PERT distribution is widely used in risk analysis [4] to represent the uncertainty of the value of some quantity where one is relying on subjective estimates, because the three parameters defining the distribution are intuitive to the estimator. The PERT distribution is featured in most simulation software tools.
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 Postsecondary Education Readiness Test (PERT) is a computer adaptive test which measures a student's level of preparedness for college-level courses. The test is currently being used by all Florida high schools and the 28 members of the Florida College System. The PERT was created by McCann Associates in cooperation with Florida educators.
In Program Evaluation and Review Techniques the three values are used to fit a PERT distribution for Monte Carlo simulations. The triangular distribution is also commonly used. It differs from the double-triangular by its simple triangular shape and by the property that the mode does not have to coincide with the median.
X-Pert is geared to producing critical path method and PERT schedules for major, long-term projects (in one case [1] a duration now approaching 40 years).. Developed by users and contributors to the ICL 1900 PERT mainframe package, X-Pert is one of the few packages still fully supporting the activity on arrow project network process.
Pert Plus, a brand of shampoo marketed in Australia and New Zealand as Pert P e r t {\displaystyle Pe^{rt}} , an expression to calculate the expected return from a continuously compounded investment given the principal, rate, and time
This distribution for a = 0, b = 1 and c = 0.5—the mode (i.e., the peak) is exactly in the middle of the interval—corresponds to the distribution of the mean of two standard uniform variables, that is, the distribution of X = (X 1 + X 2) / 2, where X 1, X 2 are two independent random variables with standard uniform distribution in [0, 1].
