Question

Carbondale Casting produces cast bronze valves on a 10-person assembly line. On a recent day, 160 valves were produced during an 8-hour shift. a) Calculate the labor productivity of the line. b ) John Goodale, the manager at Carbondale, changed the layout and was able to increase production to 180 units per 8-hour shift. What is the new labor productivity per labor-hour? c) What is the percentage of productivity increase?

Answer 1

Answer:

(a) 2

(b) 2.25

(c) 12.5%

Explanation:

To solve this question we need to remember that

$Total \, Productivity = \frac{Total\,Ouput}{Total \, Man \, Hours}$

(a) 10 persons produce 160 valves in 8 hours, this implies a productivity of 2=160/(8x10)

(b) 2.25= 180/(8x10)

(c) Percentage change is given by (2.25-2)/2=.125
