Eoq with limited backorder delays
Computers & Operations Research, 1984This note extends the standard EOQ model to cover the situation when the firm is allowed, at no backorder cost, a certain delay time before the order must be filled. This situation is met in practice when the customer doesn't expect or insist on immediate receipt of an order from on-the- shelf inventory, but only a certain reasonable delay time is ...

Abstract In this paper, we provide analytical support for the notion that it may be possible, via operational adjustments alone, to significantly reduce emissions without significantly increasing cost. Using the EOQ model, we provide a condition under which it is possible to reduce emissions by modifying order quantities.

Since the introduction of the economic order quantity (EOQ) model by Harris (1913), frequent contributions have been made in the literature toward the development of alternative models that overcome the unrealistic assumptions embedded in the EOQ formulation.

Zero Inventory (ZI) is a new and powerful concept to improve production efficiency. Underpinning ZI is set up reduction and this paper examines what eventuates when set up costs are cut. The folklore is that set up reduction lowers inventory and costs. We obtain results contrary to that.

AN EOQ MODEL WITH CONTROLLABLE SELLING RATE [PDF]
Asia-Pacific Journal of Operational Research, 2008 According to the marketing principle, a decision maker may control demand rate through selling price and the unit facility cost of promoting transaction. In fact, the upper bound of willing-to-pay price and the transaction cost probably depend upon the subjective judgment of individual consumer in purchasing merchandise.

Despite the criticisms of Woolsey [25] and others, the classical “EOQ” model of Inventory Theory remains useful, both pedagogically and as a stepping-stone towards more realistic variants. Prominent among these are: (a) the one in which stock-outs are permitted but penalized, and (b) the one in which deliveries are gradual (i.e., continuous) rather ...

EOQ Models with Supply Disruptions
2013Most of the early research in inventory theory concentrates purely on demand uncertainty. However, models which aim to capture the dynamics of real-world systems must also take uncertainties in the supply side into consideration. One type of supply uncertainty that has attracted considerable attention during the past decade is supply disruptions, such ...

This paper deals with a new approach of linguistic dichotomous fuzzy variables for a classical backordered EOQ (Economic Order Quantity) model with PE (Promotional Effort) and selling price dependent demand rate. In practice, we have observed that the demand rate during a shortage period decreases with time.

In stock management, Economic Order Quantity (EOQ) is an important inventory management system that demonstrates the quantity of an item to reduce the total cost of both handling of inventory (Handling Cost) and order processing (Ordering Cost). The purpose of determining the EOQ is to minimise the Total Incremental Cost (TIC), beyond the cost of ...
