So, efficiency is related to the relationship between inputs and outputs. the higher the rate of transport and withdrawal and the expansion of storage places with the possibility of increasing unloading and loading, the higher the port's productivity rate and the lower the average total costs. The possible capacity of the berths that supply the rest of the port operations can be calculated through several indicators, perhaps the most important of which are the following1 -Quantity of goods handled per berth = Quantity of loaded and unloaded goods/ Number of berths2 -Quantity of traded goods per foot or linear meter of berth = Quantity of shipped and unloaded goods at each berth / Number of foot or linear meter of berth. This indicator is one of the important applied indicators. it is assumed that each linear meter must achieve a certain productivity. If it exceeds this productivity, this indicates that the berth is operating beyond its capacity, which requires an effort to expand the berths of the port. This indicates that the berth is not only operating below capacity, but also the performance is inefficient.3 -Number of tons traded according to number of cells or rooms on the ship, and according to average productivity of working groups in each cell per hour, for different types of goods. Calculating possible capacity of berths varies according to nature of berth, which means that each type of berth has its own way of calculating the possible capacity. The following show that: %u2022For multi-purpose berths calculate possible capacity of berth productivity in the cycle of winch or the crane operating in handling of goods from ship, and the capacity of the tone load of the winch through one crane for each type of goods, and accordingly, Possible production capacity of crane or lever per hour (i) = (m) %u00d7 (f) where i = Possible production capacity of crane or lever per hour. m = average number of turns of the winch per hour. f = average weight of the winch's load per single lever. Calculating average of each possible production capacity and actual performance of berth per hour requires determining types of goods traded on berth on a regular basis and grouping them into broad categories, then calculating average performance for each category according to the following steps:
