Question

QUESTION 23 Current challenges in operations Management include all of the following EXCEPT: lean operations increased communication cost. rapid product development. sustainability mass customization how many hours would the plant have to work to produce 1000 parts? QUESTION 24 A small metal shop operates 10 hours each day, producing 100 parts/hour. If productivity were increased 20 between 9 and 10 hours between 2 and 6 hours less than 2 hours between 6 and 8 hours between 8 and 9 hours QUESTION 25 Although the number of people employed in manufacturing in the United States has decreased since 1950, each person is now producing almost 50 times more than in 1950 True False

Answer 1

1) Solution: increased communication cost

Explanation: Current challenges in operations management are the supply chain partnering, global focus, sustainability, mass customization, rapid product development, and lean operations

　

2) Solution: between 8 and 9 hours

Explanation: In 10-hour shift 100 parts are produced; thus in 1 hour there are 10 parts

When labor productivity increases by 20%; the increase in hours 1 - 20% = 0.9

10 parts/ hour * 0.9 = 9 hours

3) Solution: True

Explanation: Since 1950, in U.S. in manufacturing each person is producing now nearly 50 times more than in 1950

　

4) Solution: 14.4 covers/hr

Explanation: In 10-hour shift 120 covers are produced; thus in 1 hour there are 12 covers

When labor productivity decreases by 20%; the increase in hours 1 + 20% = 1.2

Thus, (12 covers/hr x 1.2) = 14.4

　

5) Solution: 2 covers/hr

Explanation: 16 covers / 8-hour shift = 2 covers/hr

　

6) Solution: 150 valves/hr

Explanation: 1200 valves / 8-hour shift = 150

Answer 2

A small metal shop operates 10 hours each day, producing 100 parts/hour. If productivity were increased 20%, how many hours would the plant have to work to produce 1000 parts?
