Hub Location and Hub Network Design

点击翻译按钮获取中文摘要

Hubs are an important component of various transportation and telecommunications networks, functioning as switching, sorting, and connection points, as well as consolidation or break-bulk terminals. In transportation networks, a hub is a place where passengers and cargo are exchanged between vehicles or transportation modes. Examples of public transportation hubs include airports, railway stations, metro stations, and bus terminals. Freight hubs, on the other hand, may be truck terminals, classification yards, seaports, or any combination of these (intermodal terminals). Hubs in telecommunications networks include switches, routers, and concentrators.
