  2. Maynard operation sequence technique - Wikipedia

    en.wikipedia.org/wiki/Maynard_Operation_Sequence...

    Maynard operation sequence technique (MOST) [1] is a predetermined motion time system that is used primarily in industrial settings to set the standard time in which a worker should perform a task. To calculate this, a task is broken down into individual motion elements, and each is assigned a numerical time value in units known as time ...

  3. Methods-time measurement - Wikipedia

    en.wikipedia.org/wiki/Methods-time_measurement

    Plots of the levelled times for the various motions were drawn. Analysis determined the best definitions of limits of motions and their major, time-determining variables, and resulted in, more or less, the structure which the manual motions of MTM-1 have today. Later work, using Time Study, gave the table of Body Motions.

  4. Mental chronometry - Wikipedia

    en.wikipedia.org/wiki/Mental_chronometry

    Based on thousands of individuals, neuroticism was found to be a negative correlate (corrected r = -.12 with the withdrawal and volatility aspects) and the enthusiasm aspect of extraversion was found to be a positive correlate (corrected r = .21 with simple reaction time, .15 with choice reaction time, and .16 with choice movement time).

  5. Computational problem - Wikipedia

    en.wikipedia.org/wiki/Computational_problem

    For example, in the factoring problem, the instances are the integers n, and solutions are prime numbers p that are the nontrivial prime factors of n. An example of a computational problem without a solution is the Halting problem. Computational problems are one of the main objects of study in theoretical computer science.

  6. Work measurement - Wikipedia

    en.wikipedia.org/wiki/Work_measurement

    Work Measurement is a technique for establishing a Standard Time, which is the required time to perform a given task, based on time measurements of the work content of the prescribed method, with due consideration for fatigue and for personal and unavoidable delays.

  7. Sample size determination - Wikipedia

    en.wikipedia.org/wiki/Sample_size_determination

    The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample. In practice, the sample size used in a study is usually determined based on the cost, time, or convenience of collecting the data, and the need for it to offer sufficient statistical power. In complex studies ...

  8. Time and motion study - Wikipedia

    en.wikipedia.org/wiki/Time_and_motion_study

    A time and motion study (or time-motion study) is a business efficiency technique combining the Time Study work of Frederick Winslow Taylor with the Motion Study work of Frank and Lillian Gilbreth (the same couple as is best known through the biographical 1950 film and book Cheaper by the Dozen). It is a major part of scientific management ...

  9. Back-of-the-envelope calculation - Wikipedia

    en.wikipedia.org/wiki/Back-of-the-envelope...

    Perhaps the most influential example of such a calculation was carried out over a period of a few hours by Arnold Wilkins after being asked to consider a problem by Robert Watson Watt. Watt had learned that the Germans claimed to have invented a radio-based death ray, but Wilkins' one-page calculations demonstrated that such a thing was almost ...
