  2. Program evaluation and review technique - Wikipedia

    It can be understood as representing the time, effort, and resources required to move from one event to another. A PERT activity cannot be performed until the predecessor event has occurred. PERT sub-activity: a PERT activity can be further decomposed into a set of sub-activities. For example, activity A1 can be decomposed into A1.1, A1.2 and A1.3.

  3. PERT distribution - Wikipedia

    en.wikipedia.org/wiki/PERT_distribution

    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

  4. Critical path method - Wikipedia

    en.wikipedia.org/wiki/Critical_path_method

    This determines the shortest time possible to complete the project. "Total float" (unused time) can occur within the critical path. For example, if a project is testing a solar panel and task 'B' requires 'sunrise', a scheduling constraint on the testing activity could be that it would not start until the scheduled time for sunrise. This might ...

    The Behrens–Fisher distribution, which arises in the Behrens–Fisher problem. The Cauchy distribution , an example of a distribution which does not have an expected value or a variance . In physics it is usually called a Lorentzian profile , and is associated with many processes, including resonance energy distribution, impact and natural ...

  6. Earned value management - Wikipedia

    en.wikipedia.org/wiki/Earned_value_management

    It is helpful to see an example of project tracking that does not include earned value performance management. Consider a project that has been planned in detail, including a time-phased spend plan for all elements of work. Figure 1 shows the cumulative budget (cost) for this project as a function of time (the blue line, labeled PV). It also ...

  7. Talk:Gantt chart - Wikipedia

    en.wikipedia.org/wiki/Talk:Gantt_chart

    The example contains PERT calculations which have nothing whatsoever to do with Gantt and were not developed until around 40 years after his death. May I refer the author and others interested in the subject to two excellent papers from Patrick Weaver; ‘Henry L Gantt, 1861 – 1919.

  8. Critical chain project management - Wikipedia

    en.wikipedia.org/wiki/Critical_chain_project...

    The application of CCPM has been credited with achieving projects 10% to 50% faster and/or cheaper than the traditional methods (i.e., CPM, PERT, Gantt, etc.) developed from 1910 to 1950s. [2] According to studies of traditional project management methods by Standish Group and others as of 1998, only 44% of projects typically finish on time.

  9. Assignment problem - Wikipedia

    en.wikipedia.org/wiki/Assignment_problem

    Worked example of assigning tasks to an unequal number of workers using the Hungarian method. The assignment problem is a fundamental combinatorial optimization problem. In its most general form, the problem is as follows: The problem instance has a number of agents and a number of tasks.
