Cross-docking logistics practice distributes products directly from supplier to customer with minimal handling or storage time
Facilities typically have rectangular or "I" shaped design
Inbound docks on one side
Outbound docks on the other
Facilitates quick transfer of goods
Categorized into pre-distribution and post-distribution models
Pre-distribution sorting occurs before arriving at cross-dock facility
Post-distribution sorting happens after arrival
Aims to reduce handling, storage, and transportation costs while improving delivery speed
Requires sophisticated coordination and real-time information sharing among supply chain partners
Success often depends on high volumes and consistent demand patterns (consumer packaged goods, retail)
Hub-and-Spoke System Overview
Central hub serves as sorting and consolidation point for multiple origin-destination pairs
Connected by transportation "spokes" (highways, air routes)
Shipments consolidated at hub allow for more efficient use of transportation resources
Economies of scale achieved through consolidation
Applied at various scales
Regional distribution networks (UPS ground shipping)
Global air freight systems (FedEx international shipping)
Improves vehicle utilization and reduces transportation costs
Ability to serve wider geographic area efficiently
Potential for increased transit times on some routes
Vulnerable to disruptions at central hub (weather delays at major airports)

Key Terms to Review (15)
Cross-docking: Cross-docking is a logistics practice where incoming shipments are directly transferred to outgoing vehicles with minimal to no storage time in between. This approach streamlines the supply chain by reducing inventory holding costs and increasing the speed of product delivery to customers.
Direct Shipping: Direct shipping refers to a logistics method where products are sent directly from the supplier to the customer without passing through a central distribution center or warehouse. This approach streamlines the shipping process, reduces handling time, and can lead to faster delivery times, making it a valuable strategy for businesses aiming to enhance customer satisfaction and operational efficiency.
Distribution Network Design: Distribution network design refers to the process of determining the most efficient and effective way to distribute goods from manufacturers to consumers. This involves selecting the locations of distribution centers, warehouses, and transportation routes to optimize service levels and minimize costs. A well-designed distribution network is crucial for meeting customer demands while aligning logistics operations with broader corporate strategies.
Hub-and-spoke system: A hub-and-spoke system is a logistical model that centralizes the distribution of goods through a central hub, which connects to multiple spokes representing various destinations. This approach allows for efficient routing and consolidation of shipments, reducing transportation costs and improving delivery times. The system is commonly used in transportation networks, such as airlines and freight systems, to streamline operations and optimize resource utilization.
Inventory management: Inventory management is the process of overseeing and controlling the ordering, storage, and use of a company's inventory. It ensures that a business has the right amount of stock on hand at all times to meet customer demand while minimizing costs and maximizing efficiency.
Just-in-time delivery: Just-in-time delivery is a logistics strategy aimed at reducing inventory carrying costs by receiving goods only as they are needed in the production process, thus minimizing waste and improving efficiency. This approach relies heavily on accurate demand forecasting and effective supply chain management to ensure that products arrive exactly when they are needed, avoiding excess stock and storage costs.
Lead Time: Lead time refers to the total time taken from the initiation of a process until its completion, particularly in logistics and supply chain management. This concept encompasses various stages including order processing, production, and transportation, making it a critical factor in overall efficiency and customer satisfaction.
Logistics service quality: Logistics service quality refers to the measure of how well logistics services meet the needs and expectations of customers. It encompasses various dimensions such as reliability, responsiveness, accuracy, and communication, which together contribute to customer satisfaction and loyalty. High logistics service quality is essential for optimizing supply chain performance and ensuring efficient operations within systems like cross-docking and hub-and-spoke models.
Order Accuracy: Order accuracy refers to the degree to which customer orders are fulfilled correctly, including the right items, quantities, and conditions as requested. It is essential for maintaining customer satisfaction and trust, impacting various logistics activities from order processing to delivery.
Order Fulfillment: Order fulfillment is the complete process of receiving, processing, and delivering customer orders to ensure timely and accurate delivery of products. This process connects various activities such as inventory management, warehousing, and logistics, ultimately affecting customer satisfaction and operational efficiency.
Supply Chain Visibility: Supply chain visibility refers to the ability to track and monitor all elements of the supply chain in real time, providing stakeholders with insights into the status of inventory, shipments, and overall logistics operations. This transparency enhances decision-making, optimizes inventory management, and improves responsiveness to market demands, ultimately leading to more efficient and effective supply chain processes.
Third-party logistics: Third-party logistics (3PL) refers to the outsourcing of logistics and supply chain management functions to a specialized provider. This includes services such as transportation, warehousing, inventory management, and order fulfillment. By leveraging the expertise of a 3PL provider, companies can enhance their operational efficiency and focus on their core business activities while also reducing costs and improving service levels.
Throughput: Throughput is the measure of how much work or production is completed within a given time frame, often associated with the efficiency and effectiveness of operations. In logistics, it reflects the rate at which goods are processed through various stages of the supply chain, impacting order fulfillment, transportation efficiency, and inventory management. By maximizing throughput, organizations can improve responsiveness to customer demands and reduce lead times.
Transportation Management System: A transportation management system (TMS) is a software platform designed to help businesses plan, execute, and optimize the physical movement of goods. It provides tools for managing transportation operations, which can include route planning, freight auditing, and shipment tracking. By facilitating better coordination between carriers, shippers, and logistics service providers, a TMS enhances supply chain efficiency and reduces costs.
Warehouse management system: A warehouse management system (WMS) is a software application designed to support and optimize warehouse or distribution center management operations. It enhances the efficiency of warehouse processes such as inventory tracking, order fulfillment, and shipping logistics by providing real-time data and automation features. This technology plays a vital role in various logistics strategies, including cross-docking and reverse logistics, ensuring smooth operations and effective resource utilization.
