Carbondale Casting produces cast bronze valves on a
12-person
assembly line. On a recent day,
180
valves were produced during
a
44-hour
shift.
a) Labor productivity of the line =
valves/labor hour (round your response to two decimal places).
b) John Goodale, the manager at Carbondale, changed the layout and was able to increase production to
220
units per
44-hour
shift. The new labor
productivityequals=
valves/labor hour (round your response to two decimal places).
c) The percentage of productivity
increaseequals=%
(round your response to one decimal place).
Homework Answers
Solution(a)
Given in the question
Total no. of valves produced = 180
No. of hours = 44
Labour productivity of line = 180/44 = 4.09 valves / labour
hour
Solution(b)
Total no. of valves produced = 220
Total hours =44
labour productivity = 220/44 = 5 valves/ labour hour
Solution(c)
Increase in productivity percentage = (New productivity - Old
Productivity)/Old productivity = (5-4.09)/4.09 = 0.222 or 22.2%

need help on C
Concord Artworks creates hand-painted picture frames. The frames are cast from resin in an automated process. Once the casting is done, talented artisans hand-paint one of fifteen designs on each frame. In the final assembly process, a worker inserts the glass pane and attaches the backing to the frame. Concord's budget for the current year, along with the production requirements for two of the frames it produces, are as follows: Direct labor hours Machine hours Manufacturing...

The Goodparts Company produces a component
that is subsequently used in the aerospace industry. The component
consists of three parts (A, B, and C) that are purchased from
outside and cost 40, 35, and 15 cents per piece, respectively.
Parts A and B are assembled first on assembly line 1, which
produces 155 components per hour. Part C undergoes a drilling
operation before being finally assembled with the output from
assembly line 1. There are in total six drilling machines,...
