The net operating hours of the vessel on the first day were eight hours and were operated for 16 hours on the second day, 16 hours on the third day. On the fourth day, one rode was operated because it coincided with the weekly holiday. The vessel left the pier at 1800 hours after all the unloading and unloading operations had been completed, but it had to wait until the travel permit was terminated and left the port at 2100. 4500 tons were unloaded and 300 tons were loaded for this vessel. Required: Analysis of the efficiency of the operation of this vessel based on labor productivity standards, knowing that the daily cost of this vessel is equivalent to $ 4000?Summary of data- Total net operating hours = 8 + 16 + 16 + 8 = 48 hours.- The total amount of cargo unloaded and shipped to this vessel = 4500 + 300 = 4800 tons.- Total hours of survival of the vessel beside the pier, regardless of whether or not it operates = 82 hours.- Total hours of vessel's stay at the port as a whole = 113 hours.1 - Labor productivity in one hour of operation =(Unloaded + charged) %u00f7 total hours of stay in the port= (4500 + 300) 48 48 = 100 tons per net working hour.
