by optimal routes, flows and connections, 

network models in operations research are like maps that help us solve real problems. They show how things are connected, like roads or pipelines. we use these models to find the best ways to transport things, like goods or information, between places.

In essence, network models provide a systematic approach to tackling complex problems involving routes, flows, and connections in diverse domains, aiding decision-makers in making informed choices to optimize resources and outcomes.
