networkslogistics

Networkslogistics is an interdisciplinary field that studies how networks of suppliers, facilities, and transportation links are designed and managed to move goods and information from origin to consumption. It combines concepts from network theory, operations research, and logistics management to analyze the structure of a logistics network, flows on its edges, capacities at its nodes, and the performance of the entire system, including cost, time, reliability, and service levels.

Key concepts include network design and facility location, capacity planning, routing and scheduling, inventory management, and transportation optimization, with emphasis on last-mile delivery. Methodologies span graph theory, linear and integer programming, network flows, shortest-path algorithms, vehicle routing problems, stochastic programming, simulation, and data analytics. The field emphasizes robustness and resilience to disruptions, uncertainty in demand, and variability in supply.

Applications span manufacturing, retail, e-commerce, third-party logistics, humanitarian aid, and healthcare supply chains. Networkslogistics seeks to reduce total costs, improve service levels and lead times, increase network throughput, and enhance visibility and traceability. It also addresses sustainability by optimizing routes, modal choices, and network configurations to minimize energy use and emissions while maintaining reliability.

Relation to related disciplines and data sources: it intersects with supply chain management, transportation engineering, and industrial engineering and relies on data from ERP, WMS, and TMS systems, as well as IoT sensors and external data feeds. Advances in artificial intelligence, machine learning, and real-time analytics continue to extend its capabilities for predictive planning and adaptive routing.
