therbligs

therbligs

a coding system which breaks down the elements of a JOB into a number of discrete tasks. For example, therbligs could include ‘search’ (attempting to find an item manually or visually), ‘grasp’ (gaining control of an item by touch or grasping), ‘position’ (aligning an item for purposes of assembly) etc. By analysing a work task in this way, it may be possible to find ways of improving the methods used to do the job. See METHOD STUDY.

Este estudio empleo las tecnicas de ingenieria de metodos en el proceso de recoleccion manual de naranjas, con el fin de conocer la operacion e identificar los macro-movimientos y los micro-movimientos o therbligs. Para su realizacion se llevo a cabo un registro videografico de los movimientos, tomado como referencia los lineamientos de la Organizacion Internacional del Trabajo (OIT) [22].
A continuacion se describen los elementos del proceso de recoleccion y los macromovientos y los therbligs identificados segun los resultados obtenidos en el estudio.
A partir del analisis de imagenes se identificaron los micromovimientos o Therbligs en el proceso de recoleccion que se esquematizan en la Figura 8, con las lineas punteadas.
Los Therbligs efectivos son los movimientos que optimizan el proceso de recoleccion de naranja, por tanto, para el desarrollo de herramientas de recoleccion debe enfatizarse en reducir o eliminar movimientos que son innecesarios este ciclo ideal, como son sostener el fruto y colocarlos en posicion.

In production management field, the methods of motion analysis include therbligs, MTM (methods-time measurement) [32], MOST (Maynard operation sequence technique) [33], and MODAPTS (The modular arrangement of predetermined time standards).
A Novel Method for Acquiring Engineering-Oriented Operational Empirical Knowledge
The well-established micro-motion studies' methodology, originated in twentieth century, emphasizes on: (1) a top-down segmentation of a primary task into basic motion elements ('Therbligs'); (2) recording of elements and key subtask performance in process-charts; and (3) obtaining metrics of performance for skill evaluation.
Apart from considering representative manipulation exercises from da Vinci surgical (SKILLS) simulator, real surgical videos were also analyzed with a list of predefined 'Therbligs' in order to validate the clinical relevance of this method.

Task analysis has its roots in the work of Gilbreth and Gilbreth (1921), who recorded elementary operations called therbligs. A related development from this early work is the representation of tasks in network models for purposes such as estimating the completion time of the task and determining the allocation of resources (e.g., Elmaghraby, 1977; Modor & Phillips, 1970; Pritsker, 1979; Wiest & Levy, 1977).

These units were known collectively as "therbligs"--Gilbreth spelled backwards, with the `th' transposed.
