Question

A mixing drum at Salvador’s, construction company mixes the highest quality concrete on the east coast. This mixing drum is available 18 hours a day. It produces about 10 pounds of concrete a day. As this construction company makes several kinds of concrete a day, they have to stop the machine and change over to a new type of concrete a few times a day. Each pound of concrete takes about 60 minutes to produce. Within this 60 minutes, 50 minutes are actual production and 10 minutes are allocated to set up the machine. Find the Overall Equipment Effectiveness of this mixing drum (round to the 2nd decimal place). Round to the nearest %

Answer 1

The percentage effectiveness o the machine is
`E= 46.30`%

Step-by-step explanation:

From the question we are told that

The availability of the mixing drum is
`A_t = 18 \ hours = 18 * 60 = 1080\ minutes`

Amount of concrete produced per day is
`C = 10lb`

time taken to produce each pound of concrete is
`t = 50 \ minutes`

Time taken to set-up the machine is
`t_t = 10\ minutes`

The time it would take to produce 10 pounds of concrete is mathematically repented as

`T = 50 * 10`

`= 500 minutes` [This is because it take 50 minutes to

to produce one pound of concrete i.e (50

minutes to produce concrete )]

Hence the equipment effectiveness of the machine is

`E = (500)/(1080) * (100)/(1)`

`E= 46.30`%
