Iceberg transport model Problems, problem analysis model, hypothesis model establishment, model solution result analysis, model evaluation First, the problem raised In the Persian Gulf to oil-rich known, the vast desert covered with earth, water resources are very scarce and have to use seawater desalination to provide water for people, cost about 0.1 pounds per cubic meter of water. Some experts suggest that the Antarctic pole be transported from icebergs to the Persian bend at a distance of 9600km, instead of fresh water. Try to establish a model to study the feasibility of iceberg transportation from the economic point of view. Two. Problem analysis In order to calculate with the tugboats tug iceberg obtained per cubic meter of the cost, we need to consider some data such as: rent, freight volume, fuel consumption, the melting ice during transport rate. Use these to prepare for modeling. To this end, we searched for the following data. 1. the daily rental and maximum volume of the three tugs. 2. fuel consumption (GBP / km). Mainly depends on the speed and the tip of the transport volume, the ship can be neglected. 3., the melting rate (i.e., M / D) during iceberg transport. The depth at which an iceberg melts daily in contact with the sea or atmosphere. In addition to the melting rate and the speed of the iceberg and the Antarctic distance and transportation process, this is due to the Antarctic icebergs from the equator to reason. (in transit to the equator, the rate of temperature increases and the rate of melting accelerates. When a certain distance is reached, at the point of demarcation, the velocity is not related to the distance) A model is designed to select the tug ship and the speed of the ship, the iceberg on arrival, can get flowers per cubic mete
