The results also suggest/indicate that it is more expensive to control the flow of a single unit of commodity for an imperfect process, i.e. a process generating defects requiring rework (Porteus, 1986), than
it is for a perfect process as assumed in the classic EOQ model.
The results further suggest/indicate that a firm, which is unable to estimate its cost parameters properly, may find that ordering in larger lots is an appropriate policy to counter entropy effects.
