A MULTI-ITEM SUPPLY CHAIN WITH CREDIT PERIODS AND WEIGHT Freight Cost DISCOUNTS
International Journal of Production Economics, 2012Co-Authors: Yu-chung Tsao, Gwo-ji SheenAbstract:Abstract It is possible to realize considerable savings by aggregating the replenishment of a variety of items in a multi-item supply chain. This joint multi-item replenishment policy has already been widely applied in a variety of industries. This type of policy may make it possible for the retailer to take advantage of transport economies of scale by the utilization of Freight discounts for greater weight. In addition, a supplier will often extend forward financing to a retailer. In this paper, a multi-item supply chain with a credit period and weight Freight Cost discounts is considered. The retailer bears the Freight Costs, but the Freight carrier provides Freight-transport discounts that are positively related to the weight of the cargo transported. From both the individual and the channel perspectives, we deal with the dual problems of determining the ideal supplier credit period, and of the best way for the retailer to make multi-item replenishment and pricing decisions, while still maximizing profits. We outline the optimal properties and develop algorithms for solving the problems described, as well as discuss the impact of the Freight Cost discounts, the inventory holding Cost, and the interest rate on the behavior of both parties.

Channel coordination, trade credit and quantity discounts for Freight Cost
Transportation Research Part E: Logistics and Transportation Review, 2007Co-Authors: Gwo-ji Sheen, Yu-chung TsaoAbstract:Abstract In this paper we consider vendor-buyer channels subject to trade credit and quantity discounts for Freight Cost. We deal with the problems of determining the vendor’s credit period, the buyer’s retail price and order quantity while still maximizing profits. We focus on how channel coordination can be achieved using trade credit and how trade credit can be affected by quantity discounts for Freight Cost. We show that profits for both parties increase under channel coordination when the credit period is kept within an appropriate range. This range becomes wider as the discount for Freight rates increases.

A Study on the Multi-Source Replenishment Model and Coordination Lot Size Decision-Making Based on Supply-Hub
Chinese Journal of Management Science, 2010Co-Authors: Ma Shi-huaAbstract:Considering a system with multi-suppliers and a manufacturer,the lot size models of both respective replenishment and cycle replenishment from suppliers in the situation of supply-hub are presented.The analytical result shows that,when the Freight Cost of unit spare parts is sensitive to the volume of carrier,the cycle replenishment along milk road from suppliers is superior to the respective replenishment from suppliers.However,when the Freight Cost of unit spare parts is rigid to the volume of carrier,it is vice versa.Moreover,the difference of demand for different spare parts has impact on the choice of replenishment methods.

A Comparison Study on Tactics for Supply Chain Coordination When the Freight Cost is Sensitive to Order Quantity
Chinese Journal of Management Science, 2008Co-Authors: Ma Shi-huaAbstract:Considering a supply chain selling one type of product with multi-period and probabilistic customer demand,we assume the Freight Cost of unit product is sensitive to order quantity and the manufacturer undertakes products transportation,the optimal lot size models in decentralized decision are presented.The analytical result shows that the more rigid the Freight Cost of unit product to order quantity is,the smaller the optimal production lot size is, which is in accordance with short order lead time and small order quantity that claimed by the wholesaler.And,if the wholesaler,not the manufacturer,undertake products transportation,the optimal order quantity of the wholesaler will be closer to the optimal production lot size of the manufacturer.Finally,the numeral analysis shows that from the perspective of the manufacturer,when the Freight Cost of unit product is rigid to order quantity,the quantity discount policy is superior to the tactic!of the wholesaler replacing the manufacturer to undertake products transportation.However,when the Freight Cost of unit product is sensitive to order quantity,vice versa.

Lot-sizing models based on different transportation sponsors in supply chain
Computer Integrated Manufacturing Systems, 2006Co-Authors: Ma Shi-huaAbstract:Considering that the Freight Cost of unit product is sensitive to lot-sizing,the optimal lot-sizing models both with decentralized decision and integrated decision based on channel partners for different products transportation sponsors were constructed to coordinate the optimal ordering lot-sizing of a purchaser with the optimal manufacturing lot-sizing of a supplier in a supply chain.Study indicated that the more flexible the transportation capacity was,the smaller the optimal manufacturing lot-sizing was,which was in accordance with the short ordering lead time and few lot-sizing that were claimed by the purchaser.Also,it showed that the optimal ordering lot-sizing was closer to the optimal manufacturing lot-sizing when products deliverer was the purchaser,so that it might benefit the whole supply chain since the supplier and the purchaser could obtain a win-win solution.

Pareto Optimization Tactic in Supply Chain with Constraint of the Flexibility of Delivery Capacity
Industrial Engineering and Management, 2006Co-Authors: Ma Shi-huaAbstract:Considering a supply chain with a manufacturer and a wholesaler,we assume the Freight Cost of unit product is sensitive to lot-size and the manufacturer is responsible for products delivery,the optimal lot-size models in decentralized decision and centralized decision are presented.The analytical result shows that the more flexible the delivery capacity is,the smaller the optimal manufacturing lot-size is,which is in accordance with short ordering lead time and few lot-size that claimed by the wholesaler.Therefore,the manufacturer can rapidly respond to the demand of the wholesaler under the condition that the total Cost is invariable.Moreover,when the delivery capacity is not completely flexibile,the manufacturer may suggest the wholesaler to undertake products delivery through reducing transfer price so as to make the optimal ordering lot-size of the wholesaler in decentralized decision closer to both the optimal manufacturing lot-size of the manufacturer and the ordering lot-size of the supply chain in centralized decision,which may benefit the whole supply chain since the manufacturer and the wholesaler can obtain a win-win solution.

An integrated inventory model for single-vendor single-buyer system with Freight rate discount and stochastic demand
International Journal of Operational Research, 2016Co-Authors: Wakhid Ahmad Jauhari, Ayudia Fitriyani, Azizah AisyatiAbstract:This paper deals with joint economic lot sizing model (JELS) in the context of two stage supply chain comprising of single-vendor and single-buyer. The shipment from vendor to buyer is conducted in equally sized and the demand in buyer side is assumed to be normally distributed. In this paper, Freight Cost is explicitly incorporated in the model and formulated by all-weight Freight discount model and incremental Freight discount model. We provide two procedures to find the optimal shipment size, safety factor, production batch and discount level on both models. Numerical examples are presented to illustrate the benefit of the model. The result shows that incorporating Freight discount into inventory model may result in significant saving on total Cost. The increase in the number of discount levels will lead to the decrease in buyer Cost and total Cost. Moreover, it also shows that the changes in ordering Cost, purchase Cost, setup Cost and production rate in incremental Freight discount model give significant impacts on shipment size and safety factor.

Buyer’s response to a temporary price reduction incorporating Freight Costs
European Journal of Operational Research, 2007Co-Authors: Prakash L. AbadAbstract:Abstract In this paper, we characterize the buyer’s response to a temporary price reduction. Although there have been many studies that have considered the above problem, most of those studies assume that the buyer orders FOB (free on board) destination and that the Freight charges are included in the supplier’s unit price. Our model thus becomes applicable for a buyer whose strategy is to include transportation Costs in their purchase decisions. The buyer may want direct control on his inbound logistics Costs. The company may have outsourced its logistics function and as a result is charged for Freight as invoiced by the public motor carrier. In some cases, the supplier may only allow for orders that are FOB origin. Our model allows for less-than-truckload as well as truckload rates. Freight Cost for a LTL shipment is modeled using tariffs set by public carriers in practice. These tariffs generally involve 6–7 breakpoints in terms of the weight of the shipment. Another complication in practice is that the shipper/buyer has an option to over-declare the weight of the shipment.

Optimal single period order size under uncertain demand incorporating Freight Costs
International Journal of Services and Operations Management, 2006Co-Authors: Prakash L. AbadAbstract:There is now greater scrutiny of Freight Costs by buyers who want to control inbound logistics Cost. In this study, we consider the lot size problem faced by a buyer who plans product availability for a style good which has uncertain demand for the season. The buyer has only one opportunity to procure the good prior to the season and is responsible for paying for the Freight. A buyer may opt for paying for the Freight if he sees an opportunity for savings on Freight Costs. In some cases, the supplier may allow only for FOB origin orders. The order may span several truckload shipments and a remnant less-than-truckload shipment. We represent the Freight Cost for a less-than-truckload shipment by Freight tariffs offered by public motor carriers, in practice. These Freight tariffs typically entail six to seven breakpoints in terms of the weight of the shipment.
