  2. Work measurement - Wikipedia

    en.wikipedia.org/wiki/Work_measurement

    Work measurement is the application of techniques which is designed to establish the time for an average worker to carry out a specified manufacturing task at a defined level of performance. [1] It is concerned with the duration of time it takes to complete a work task assigned to a specific job.

  3. PFD allowance - Wikipedia

    en.wikipedia.org/wiki/PFD_allowance

    The fatigue allowance is intended to cover the time that the worker should be given to overcome fatigue due to work related stress and conditions. There are three factors that cause fatigue: (1) physical factors like standing and use of force, (2) mental and cognitive factors like mental strain and eye strain , and (3) environmental and work ...

  4. Standard time in manufacturing - Wikipedia

    en.wikipedia.org/wiki/Standard_time_in_manufacturing

    Standard time is the amount of time that should be allowed for an average worker to process one work unit using the standard method and working at a normal pace. The standard time includes some additional time, called the contingency allowance, to provide for the worker's personal needs, fatigue, and unavoidable delays during the shift.

    The hourglass is often used as a symbol representing the passage of time Clocks; a watch-maker seated at his workbench. Chronometry [a] or horology [b] (lit. ' the study of time ') is the science studying the measurement of time and timekeeping. [3]

  6. German units of measurement - Wikipedia

    en.wikipedia.org/wiki/German_units_of_measurement

    The units of measurement of German-speaking countries consist of a variety of units, with varying local standard definitions. While many were made redundant with the introduction of the metric system, some of these units are still used in everyday speech and even in stores and on street markets as shorthand for similar amounts in the metric system.

    In 1948, Maynard, Stegemerten and Schwab published the book “Methods-Time Measurement” giving full details of the development of the MTM system and its application rules. The use of Methods-Time Measurement MTM spread, first in the USA and then to other industrialized countries. In 1951 the USA / Canada MTM Association for Standards and ...

  8. Standard time (manufacturing) - Wikipedia

    en.wikipedia.org/wiki/Standard_time_(manufacturing)

    In industrial engineering, the standard time is the time required by an average skilled operator, working at a normal pace, to perform a specified task using a prescribed method. [1] It includes appropriate allowances to allow the person to recover from fatigue and, where necessary, an additional allowance to cover contingent elements which may ...

  9. Unit of time - Wikipedia

    en.wikipedia.org/wiki/Unit_of_time

    The Jiffy is the amount of time light takes to travel one femtometre (about the diameter of a nucleon). The Planck time is the time that light takes to travel one Planck length. The TU (for time unit) is a unit of time defined as 1024 μs for use in engineering. The svedberg is a time unit used for sedimentation rates (usually
