What is Network Optimization?
Network optimization refers to the process of improving the efficiency, performance, and reliability of a computer, communication, or supply chain network. It involves analyzing network structures, traffic patterns, resource allocation, and system constraints to achieve optimal flow, minimum delays, and maximum throughput.
Definition
Network optimization is the application of mathematical models, algorithms, and engineering techniques to enhance the performance, speed, capacity, and cost-efficiency of interconnected systems.
