Quantity Model (EMQ)
Quantity
EOQ model states that the items are obtained from an
outside supplier. (then the assumption is that entire lot is
delivered at the same time)
delivered
If we want to use EOQ when the units are produced
internally, then the assumption is that the production
rate is infinite. When the production rate is much larger
than demand, EOQ model holds.
than
However when the production rate is smaller than
demand, EOQ model leads to incorrect results.

Suppose that items are produced internally at a rate P >
