Ship-pack replenishment optimization in a two-echelon distribution system with lost sales and seasonal product obsolescence
As a retailer attempts to leverage a two-echelon distribution system to forward-deploy inventory, a number of cost elements must be considered when deciding the quantity of a given SKU to replenish to the forward-deployed node. These costs include processing costs, transportation costs, and …

E-Commerce drop shipping : building a CPG supply chain
… by drop shipping as a means of capturing lost sales on high-value, seasonal products that retailers might be under-stocking. These manufacturers currently lack the retailer-side inventory availability information to assess the extent of this opportunity. We propose a framework to show …

Management of a high mix production system with interdependent demands: global and decomposed optimization approaches for inventory control
… of the inventory and the expected number of lost sales as compared to a simple reorder point policy or to the policy currently in use at the company. A reduction of 35% of inventory and of almost 10 times of the average value of lost sales is expected if the company substitutes the current …

Measuring the value of a responsive supply network
… to unpredictable market demand and minimize lost sales. Reduction in lost sales leads to growth in sales. LargeCo is interested in finding out if its responsive supply chain is contributing to sales growth. In particular, LargeCo would like to determine whether improvement in KPIs, driven by …

Managing Disturbances in Supply Chain Systems
… cost parameters such as, back orders and lost sales costs, and to the disturbance duration. For a certain range of disturbance duration and cost values, it was found that back orders were more attractive, and in such cases, back orders cost was less than the lost sales cost. On the other …

Detailed Inventory Record Inaccuracy Analysis
… method performs better on stock-out and lost sales, whereas error control method keeps lower inventory. Furthermore, this research also investigates the value of using a secondary source of information (automated data capturing) along with traditional inventory record keeping methods to …

Demand bubbles and phantom orders in supply chains
… ways. First, a negative feedback loop of lost sales captures the effect that an initial increase (decrease) in demand leads to a decrease (increase) in the manufacturer's service level, causing customer demand to decrease (increase). Second, a positive feedback loop of production push …

Inventory estimation from transactions via hidden Markov models
… are unaccounted. Even more important are the lost sales due to lack of items on the shelf, called stockout losses. In several industries, stockout is responsible for billions of dollars of lost sales each year (cf. [4]). In [5], it is estimated that 4% of annual sales are lost due to stockout, …

Dynamic decision-making under uncertainties: algorithms based on linear decision rules and applications in operating models
… lifetime is analyzed. Both the backlogging and lost-sales cases are discussed. The analytic results shed new light on perishable inventory management, and the proposed approach provides a significantly simpler proof of a classical structural result in the literature. Two heuristics were …

New approaches for integrating revenue and supply chain management
… upon arrival. Rejected customers incur a lost-sales cost, while accepted customers are satisfied with minimum possible production cost. The goal of the supplier is to minimize the total cost of lost sales and production. We provide algorithms with strong performance guarantees that are …

Heuristics for Inventory Systems Based on Quadratic Approximation of L-Natural-Convex Value Functions
… three well-studied inventory models, namely the lost-sales system, the perishable inventory system, and the joint inventory-pricing problem. We approximate the value functions for these models by the class of L-natural-convex quadratic functions, through the technique of linear programming …

Management of a high mix production system with interdependent demands : simulation of proposed policies
… both as part of systems and as individual after sales items. Besides, there is uncertainty in determining replenishment lead times. An optimization problem is formulated considering customer satisfaction, inventory holding costs and correlation between demands. To ascertain its validity, a …

Analysis of additive manufacturing in an automobile service part supply chain
… Moreover, we find that service parts with high lost sales unit cost and low fixed and variable additive manufacturing costs are the most suitable for additive manufacturing.

Managing forecast variability in a build-to-order environment
… obsolescence costs of unused inventory (should sales not materialize) against potential expedite costs or lost sales (should demand outpace available inventory). For build-to-order manufacturers such as Dell, the balancing act is even more challenging. While it offers a wide array of products, …

Product promotion effectiveness : root causes of stock-outs
… demand pattern during promotions leads to lost sales incurred due to frequent stock-outs, affecting the revenue and the brand of both the manufacturer and the retailer. The research focuses on finding out the root-causes of stock-outs in retail stores. It uses the audit response data that …

ANALYSIS ON RETAILERS COLLABORATION IN SUPPLY NETWORKS
… as two to three months, which often leads to lost sales. In this project, we consider alternative distribution systems to provide insight for car dealers to improve their performance. Three systems are discussed: the current decentralized system, the collaboration system, and the centralized …

Optimal inventory model for managing demand-supply mismatches for perishables with stochastic supply
… perishables may have to live with the misery of lost sales and/or expired items. In the case of the dairy industry that deals with liquid milk, both raw material, and finished goods are perishable, which implies that merely stockpiling inventory of either item, without paying attention to …
