Question

Race One Motors is an Indonesian car manufacturer. At its largest manufacturing? facility, in? Jakarta, the company produces subcomponents at a rate of

305

per? day, and it uses these subcomponents at a rate of

12,500

per year? (of 250 working?days). Holding costs are

?$3

per item per? year, and ordering costs are

?$31

per order.

?a) What is the economic production? quantity?

nothing

units ?(round your response to two decimal? places).

b) How many production runs per year will be made? (round your responce two decimals)

c) What will be the maximum inventory level? ( round to two decimals)

d) What percentage of time will the facility be producing components? (round to two decimals)

e) what is the annual cost of ordering and holding inventory? (round to two decimals)

Explanation / Answer

Annual Demand, D = 12,500

Daily demand rate, d = 12500/250 = 50 per day

Daily production rate, p = 305 per day

Holding cost, H = $ 3 per item per day

Ordering cost, S = $ 31 per order

a) Economic Production Quantity (EPQ) = SQRT(2DS/(H*(1-d/p)))

= SQRT(2*12500*31/(3*(1-50/305)))

= 555.87

b) Number of production runs per year = D/Q = 12500/555.87 = 22.49

c) Maximum inventory level = Q*(1-d/p) = 555.87*(1-50/305) = 464.74

d) Percentage of time facility will producing components = d/p = 0.16

e) Annual cost of ordering and holding inventory = Number of production runs per year * Ordering cost + (Maximum inventory / 2) * holding cost = (D/Q)*H + (Q*(1-d/p)/2)*H

= 22.49*31 + (464.74/2)*3

= $ 1394.30
