Sindrei [870]

Answer: 8 minimum work stations is what would be needed.

Step-by-step explanation:

The cycle time is computed as the operating time daily divided by the scheduled output.

It is important to note that the daily capacity of the operation layout is the operating time divided by the cycle time.

Therefore,

If you need to produce 30units/hour.

The average cycle time is as follow:

The average cycle time is the average time between the completions of units.

60/30= 2 average cycle time

=16/2

=8

8 work stations is the minimum number that would be needed.

It is important to know that in an assembly line balancing, the minimum number of work station is the ratio of the sum of all tasks time to the cycle time.

Please answer the problem below.<br><br> ~Thanks = )
RoseWind [281]

Hi GlaxyCraft4991,

Solution:

−12x − 0.4 > 0.2 (36.5x + 80) − 55

−12x − 0.4 > 7.3x − 39

−12x − 0.4 − 7.3x > 7.3x − 39 − 7.3x

−19.3x − 0.4 > −39

−19.3x − 0.4 + 0.4 > −39 + 0.4

−19.3x > −38.6

−19.3x/19.3 > −38.6/19.3

x < 2

Correct Answer:

x < 2

How do you solve this problem? With work!!
Evgesh-ka [11]
You would put 9 times v because you are multiplying it to the 9 and you do not know what v is then you would divide it by 3 and get your answer so for example if you should have gotten 9 times v = 72 then 72 divided by 3 = 24 and 24 divided by 3 = 8
