104
Q

Learning curve

A

It is the relationship that exists between the time elapsed since the beginning of an activity and the level of learning achieved.

105
Q

Crawford model

A

In a “normal” behavior learning curve, the rate of improvement of the cycle time remains constant each time the number of pieces produced is double.

The theory of the learning curve holds that when the total number of units produced is doubled, the time per unit decreases by a constant percentage.

y - cycle time
k - value of the first cycle time
X -  number of cycle or units produced
n - exponent representing the slope

Q

Antropometría

A

Es la ciencia de la medición de las dimensiones y algunas características físicas del cuerpo humano

Permite medir longitudes, anchos, grosores, circunferencias, volúmenes, centros de gravedad y masas de diversas partes del cuerpo, las cuales tienen diversas aplicaciones.

La antropometría es una rama fundamental de la antropología física. Trata el aspecto cuantitativo.

107
Q

Alcances de antropología

A

En el campo de la salud y seguridad en el trabajo y de la ergonomía, los sistemas antropométricos se relacionan principalmente con la estructura, composición y constitución corporal y con las dimensiones del cuerpo humano en relación con las dimensiones del lugar de trabajo, las máquinas, el entorno industrial y la ropa.(OIT 1998)

108
Q

Antropometría Estática

A

Mide al cuerpo mientras este se encuentra fijo en una posición, permitiendo medir el esqueleto entre puntos anatómicos específicos, por ejemplo el largo del brazo medido entre el acromio y el codo.

Las aplicaciones de este tipo de antropometría permite el diseño de elementos como guantes, cascos entre otros.

109
Q

Antropometría dinámica

A

Funcional corresponde a la tomada durante el cuerpo en movimiento, reconociendo que el alcance real de una persona con el brazo no corresponde solo a la longitud del mismo, sino al alcance adicional proporcionado por el movimiento del hombro y tronco cuando un trabajador realiza una tarea.
