But before discussing these specific problems, the chapter briefly introduces several terminologies that serve as a precursor to network analysis and can be used as a guide to solving practical problems.

Nodes generally represent locations, such as communities, service stations, bus terminals, and so on, while branches represent flow of goods, services, messages, distance, time, etc. Branches in a graph may or may not have directions. If every branch in a graph has a direction, it is called a directed graph; if it does not, it is called an undirected graph. If, on the other hand, some of the
