While access to the number of berths optimized for the size of the expected movement of the port is important in the need to take many operational decisions in advance according to scenarios expected to operation.(2) The duration of the vessel's stay in port (vessel time)The duration of the vessel in the port can be divided into two components:A- Waiting time: The difference between the time of arrival of the ship to the port and the time of the link on a berth. There are several factors that lead to the length of this period, perhaps the most important:- Absence of vacant berths due to strikes.- Cases of opposite tide for the ship or because of strikes.B- The duration of the ship on the berth or so-called service time: The total time it takes the ship on the berth to carry out unloading and loading or just to wait without work or Idle time. There are several factors that lead to the length of this period, most notably the type of vessel, the subject of service, and the nature of the goods being handled, and in general the larger the size of the vessel and loaded with regular volumes of cargo, the less time waiting for the ship in the port. While the greater the diversity of the nature of the goods and the methods of handling them, the longer the duration of the ship's stay on the berth is long.The vessel service time = Total number of tons handled %u00f7 Actual productivity of the berth. the length of time to service vessels in the ports vary according to several factors, which are:1- Type of vessel: the general cargo vessels generally take longer to service than other types.2 - The quantity and type of cargo carried by the vessel: the more varied and varied types of cargo carried by the vessel in terms of shape and size and the way of packaging and packaging the more time of service.
