The model study of Marine functional evaluation

With the coast zone takes the function for evaluate the target, build up with the attribute of maritime space, hydrology, weather, biology, chemistry, geology, economy, transportation, resources, environment...etc. is main contents of, have simple, the ocean function evaluation mathematics model of science, objective and metered characteristic. Combine the system engineering theories, according to Multiple Objective Decision Making analysis method of the power of entropy, to take the port shipping area as an example, as to it´s the function carried on the evaluation. As a result show that four ports choose from excellent go to inferior and in proper order is a port of Qingdao, port of Qinhuangdao, port of Tianjin, port of Dalian one by one in order, the evaluation result and facts agree with.
