the existing works considering the flow-based discount factor in the hub and spoke problems, assume that increasing the amount of flow passing through each edge of network continuously decreases the unit flow transportation cost. although a higher volume of flow allows for using wider links and consequently cheaper transportation, but the unit of flow enjoys more discounts, quite like replacing...

This article studies the classical reorder quantity, order point (Q, r) continuous review stochastic inventory model with Poisson arrivals and a fixed lead time. This model has been extensively studied in the literature and its use in practice is widespread. This work extends previous research in this area by providing efficient algorithms for the computation of the optimal (Q∗, r∗) values when...

The high adoption of smart mobile devices among consumers is an opportunity for ecommerce retailers to increase their sales by recommending consumers with real time, personalized coupons which take into account the specific contextual situation of the consumer [5]. While context-aware recommender systems (CARS) have been widely analyzed [1,2] personalized pricing or discount optimization in rec...

In today’s competitive business situation, the supplier frequently offers his or her retailers a permissible delay period ( i.e. , trade credit) to stimulate sales. addition, capacity of any warehouse is limited in practice, thus retailer needs an additional rented (RW) store excess units when order quantity exceeds own (OW). Furthermore, with globalization marketing policy, may provide discoun...

This paper investigates the coordination mechanism for a supply chain with one manufacturer and two competing retailers when the demands are disrupted. This differs from conventional supply chain coordination models under a static case. We will consider different scenarios of the problem: the production deviation cost may be either incurred to the manufacturer or to the retailers; the supply ch...

The classic Economic Order Quantity model assumes that the unit purchasing cost is not based on the order quantity. In practice, a supplier may offer purchasers an all-units discount. We develop a model and solution procedure for the EOQ with all-unit discounts and partial backordering at a constant rate. We show, and illustrate with a numerical example, how that model can be used to find the s...

Supplier selection and material procurement planning are the most important issues in supply chain management. This decision is complicated when the buyers face with discount price schemes. In real situation, each supplier may apply different methods such as different types of discount schedules and various types of payment in order to increase market share. In this situation, buyers try to sel...

In this paper, we concentrate on developing a bi-fuzzy multi objective transportation problem (MOSTP) according to bi-fuzzy expected value method (EVM). In a transportation model, the available discount is normally offered on items/criteria, etc., in the form all unit discount (AUD) or incremental quantity discount (IQD) or combination of these two. Here transportation model is considered with ...

In this paper, a discount model is proposed to coordinate pricing and ordering decisions in a two-echelon supply chain (SC). Demand is stochastic and price sensitive while lead times are fixed. Decentralized decision making where downstream decides on selling price and order size is investigated. Then, joint pricing and ordering decisions are extracted where both members act as a single entity ...
