The following example will be used to illustrate the previous point.Example: Suppose that the administration of the port reached the expectation of arrival of vessels during the next year at an average daily rate of 1.2 vessels, while the possibilities available at the port cannot achieve the productivity of more than 500 tons daily for the operations of loading and unloading with all the vessels located at the port per day. According to the records and data available at the port, the mean time of service of the vessel is 2.75 days. The civil engineering sector also reported that the berths were designed and constructed to be 25 years old. The financial management of the port calculated the actual cost per berth in the port and is equivalent to 12 million pounds per berth. The annual depreciation of the berth was calculated on this basis to reach 800 thousand pounds per year or 2,200 pounds per day. It was also contacted by the shipping agencies and some ship owners, as well as shipping lines that hesitate to ship to the port to inquire about the daily cost (current and capital) for this type of vessels, it is found on the average equivalent to 10 thousand pounds. If you know that the variable cost of a ton rolling on the docks is equivalent to 10 pounds .in light of these data and information1. Calculate the number of vessels expected to arrive at this port?2 - Calculate the annual productivity of the tonnage expected to be loaded and unloaded?3. What number of berths should the port provide to serve the expected volume of traffic assuming only four berths, five berths, six berths and finally seven berths?The solutionNumber of vessels expected = Daily arrival rate of ships %u00d7 Number of days of the year = 1.2 %u00d7 365 = 438 ships per year.Quantity of tons expected to be loaded and unloaded = Number of vessels expected x Maximum daily loading and unloading capacity %u00d7 Number of days of the year %u00d7 Mean time of vessel service = 438 %u00d7 500 %u00d7 365 %u00d7 2.75 = 602250 tons / year.
