Current setup time on a certain machine is 3.0 hr. Cost of downtime on this machine is estimated at $200/hr. Annual holding cost per part made on the equipment, Ch = $1.00. Annual demand for the part is 15,000 units. Determine
(a) EOQ and
(b) total inventory costs for this data. Also, determine
(c) EOQ and
(d) total inventory costs, if the changeover time could be reduced to 6 minutes.
