Li, S. (author)
Seaports are crucial nodes in international trade and transport. Some of the cargoes arriving at seaports are transshipped to other ports, while others are transported to inland destinations. Every time an inland container vessel enters the port, it calls at many different terminals spread over the port area. Two coordination problems exist in...
