gle has a repetitive manufacturing plant producing trailer hitches in Arlington, Texas. The plant has an average inventory turnover of only 12 times per year. He has therefore determined that he will reduce his component lot sizes. He has developed the following data for one component, the safety chain clip:
Setup labor cost |
$2525 per hour |
Annual holding cost |
$1212 per unit |
Daily production |
1 comma 0081,008 units/8 hour day |
Annual demand |
36 comma 00036,000 (250250 dayseachtimes ×daily demand of144144 units) |
Desired lot size |
126126 units (one hour of production) |
To obtain the desired lot size, the set-up time that should be achieved =
5.445.44
minutes (round your response to two decimal places).
Solution:
Economic Production Quantity (Q) is calculated as,
Q = SQRT [(2 x D x S) / H x (1 - d/p)]
where,
D = Annual demand
S = Setup cost
H = Holding cost
d = Daily demand
p = Daily production
Modifying the above formula to solve for Setup cost (S), we get,
S = [(Q^2) x H x (1 - d/p)] / 2D
Putting the given values in the above formula, we get,
S = [(126^2) x $12 x (1 - 144/1008)] / (2 x 36,000)
S = $2.268
Setup cost = $2.268
Setup time is calculated as,
Setup time = (Setup cost / Setup labor cost) x 60 minutes (1 hour = 60 minutes)
Setup time = ($2.268 / $25) x 60 minutes
Setup time = 5.44 minutes

A product has annual demand of 100,000 units. The plant manager wants production to follow a four-hour cycle. Based on the following data, what setup cost will enable the desired production cycle? d=800 per day (250 days per year), p=4000 units per day, H=$40 per unit per year, and Q=400 (demand for four hours, half a day).
