Therblig

from Wikipedia, the free encyclopedia
The 18 therbligs.

Therbligs is the name of a set of basic types of movement used to describe and measure the physical activity required for an employee to perform a task. They are considered the first basis of the system of predetermined times .

The word Therblig is a reverse of the word Gilbreth when the "th" is seen as a letter. This was the creation of Frank Bunker Gilbreth and Lillian Moller Gilbreth , the American business consultants who worked in the field of time and motion studies .

The sentence consists of 18 elements, each of which describes a type of movement ("category of motion"). According to the Gilbreths, almost all human movements can be traced back to these 18 elements. According to Gilbreth, every thermal substance that does not serve the progress of work can be eliminated.

Therbligs are used to study the efficiency of movements when performing tasks in the workplace . The process is analyzed by coding each movement through the associated Therblig. In order to optimize a physical work process, unnecessary movements are sought and eliminated. The Therbligs in detail are:
