When the theory of constraints (TOC) supply chain replenishment system (TOC-SCRS) is deployed in a plant or a central warehouse, replenishment frequency (RF) becomes one of the important decision parameters and depends on the sales or replenishment quantity (RQ) in the plant. The higher RF is preferred by TOC for the low inventory and the fast response to different market requirements. However,...

In this article, we consider an infinite horizon, single product economic order quantity where demand and deterioration rate are continuous and differentiable function of price and time, respectively. In addition, we allow for shortages and completely backlogged. The objective is to find the optimal inventory and pricing strategies maximizing the net present value of total profit over the infin...

In this study, we analyze the replenishment decisions under a general replenishment cost structure that includes stepwise freight costs and all-units quantity discounts. We first formulate a general model that accounts for a larger class of problems an...

Keywords: Assemble-to-order (ATO) Inventory Stochastic program Optimal policy Multi-dimensional newsvendor model a b s t r a c t In this paper we introduce a multi-stage stochastic program that provides a lower bound on the long-run average inventory cost of a general class of assemble-to-order (ATO) inventory systems. The stochastic program also motivates a replenishment policy for these syste...

The rapid improvement in the clinical manifestations of thiamine deficiency with thiamine supplementation is well known. To study this process in more detail, we rendered rats thiamine deficient either by dietary deprivation alone (DD) or, in addition, by daily pyrithiamine administration (DD + PT). We observed the cerebral metabolic and histological responses of these rats after 1 or 7 days of...

In this paper we develop an economic order quantity model to investigate the optimal replenishment policies for instantaneous deteriorating items under inflation and trade credit. Demand rate is a linear function of selling price and decreases negative exponentially with time over a finite planning horizon. Shortages are allowed and partially backlogged. Under these conditions, we model the ret...

CPFR (Collaborative Planning Forecasting and Replenishment) has emerged as the latest business practice aiming to ensure that there is always enough quantity to meet consumer demand, while maintaining optimum levels of stock across the supply chain. The essence of CPFR is about utilizing technology capabilities and information sharing to support trading partner interaction and collaboration in ...

In this paper, an incentive scheme based on crashing lead time is proposed to coordinate a supplier-retailer supply chain (SC). In the investigated SC, the supplier applies a lot-for-lot replenishment policy to replenish its stock and determines the replenishment multiplier. Moreover, the transportation lead time is considered under the control of the supplier. The retailer as downstream member...
