摘要：In this paper, based on the EOQ (Economic
Ordering Quantity) model, we focus on the problem of wasting
which became more and more serious. Thus, we provided some
ideas to avoid wasting before the expiration date in this paper.
The expiring goods are divided into two parts, the first is
recyclable and contains residual value, and the second is
unrecyclable which waiting to be discarded. Therefore, we
combined the replenishment and recycling movement over
multiple deliveries to reduce the cost, and the residual value of
expiring item also could increase profits for buyers. This paper
assumed that the ordering cycle is determined by the demand
rate, delivery quantity per shipment, and the mathematical
expectation of the expiring item rate in a lot. The loss of the
expiring goods recycling and defective items processing are
counted into the cost. As the result, this paper establish an EOQ
inventory model for expiring items with equal-size shipment
policy to derive the optimal ordering cycle, ordering quantity,
and number of deliveries. In the end, through the theoretical
proving procedure and numerical example, then analyze the
results.
