therblig|ˈθɜːblɪg|
[Anagrammatic formation by partial reversal of the name of its inventor, F. B. Gilbreth (1868–1924), American engineer and pioneer of time-and-motion studies.]
In time-and-motion study, a unit of work or absence of work into which an industrial operation may be divided (see quot. 1921); a symbol representing such a unit.
1921F. B. Gilbreth in Bull. Taylor Soc. June 128/2 We believe that there are but sixteen sub-divisions of a cycle of motions. They are called therbligs. They are as follows: 1. Search, 2. Find,..13. Transport, empty, 14. Rest for overcoming fatigue [etc.]. 1930Movie Makers Nov. 687/1 The motions of the operator are broken down into fundamental motions known as ‘therbligs’ (Gilbreth spelled backwards). 1947[see micromotion]. 1948Ghiselli & Brown Personnel & Industrial Psychol. xi. 279 The therblig type of classification of movements is important principally in such problems as changing the sequence of movements and in the elimination of unnecessary movements. 1963Engineering 27 Dec. 826/3 Maynard intended to allocate time values to Gilbreth's therbligs. 1964A. Battersby Network Analysis ii. 13 Two main sets of symbols are used: Gilbreth's ‘therbligs’ for motion study and the standard ASME (American Society of Mechanical Engineers) symbols for method study. 1975Daily Tel. 11 Dec. 14/5 There are 18 therbligs altogether. Each has its own symbol and colour (e.g. ‘search’ is black, ‘grasp’ is red, ‘use’ is purple) and these can be used to construct simultaneous motion charts. 1976W. H. Canaway Willow-Pattern War vii. 82 She was skilled..in lovemaking, and only now and then did you get the feeling that..in her mind there was a stopwatch and a work-study chart covered with therbligs. |
