The Study On Harm Grade Evaluation Of Oil Spill From Ships At Sea

In order to prevent and deal with the oil spill pollution from ships of our country effectively, to strengthen and improve the response ability, to boost the ocean economy, as well as to preserve the water environment, the harm grade evaluation of oil spill from ships at sea must be evaluated scientifically.The harm grade evaluation of oil spill from ships at sea is an complicated multi-attribute classification issue. By the profundity analyse of the oil spilling accidents from ships at sea, pay attention to the fuzziness of the damage for the sea area. The dissertation built the harm grade evaluation of oil spill from ships at sea Maths model by fuzzy mathematics, made an application software of the harm grade evaluation of oil spill from ships at sea by Matlab 6.5.The Maths model about the vessel's oil spill harm grade evaluation evaluated the grade of oil spill according to fifteen inflection factors-oil spill volume,permanent,poisonous,flammability,sensitivity degree, distance off shore,self-purification capability,wind speed,wave height,visibility,water temperature,ship form,vessel's damage degree,vessel's age,residual oil volume, and validate with each other based on fuzzy matrix and fuzzy integral.Finally, the conclusion of the study is given, deficiency is analyzed, direction of the research is prospected. The more scientific, practical and reasonable evaluation system of the harm grade of oil spill from ships at sea is hoped to be found.
