Question

Annual demand for a new assembled product is expected to be 80,000 units. Work content time for the product is 22.7 min. The assembly line operates 50 wk/yr, 40 hr/wk. Expected line efficiency is 95%. With one worker per station, determine (a) average hourly production rate, (b) cycle time, and (c) ideal minimum number of workers.

Answer 1

average hourly production = 40 units

cycle time = 1.425 min

ideal minimum number of work = 16 worker

Step-by-step explanation:

given data

annual demand for product = 80,000 units

Work content time = 22.7 min

work for week = 50 wk/yr

no of hr/week = 40 hr/wk

efficiency = 95% = 0.95

to find out

average hourly production rate and cycle time and ideal minimum number of worker

solution

we get here average hourly production rate that is express as

average hourly production =
`(Da)/(50H)` ........1

average hourly production =
`(80000)/(50*40)`

average hourly production = 40 units

and

cycle time is

cycle time =
`(60*efficiency)/(average\ hourly\ production)`

cycle time =
`(60*0.95)/(40)`

cycle time = 1.425 min

and

ideal minimum number of work is

W = minimum integer ≥
`(time)/(cycle\ time)`

W = minimum integer ≥
`(22.7)/(1.425)`

ideal minimum number of work = 15.93 = 16 workers
