模糊最大矩阵元鉴别海面溢油

Identification of Spilled Oil at Sea Surface with Fuzzy Maximum Matrix Method.

建立了模糊最大矩阵元的海面溢油鉴别模式,提出了油种鉴别的置信水平λ_i的模糊区概念,给出了常见的14种油、两种风化油和海面溢油的模糊动态聚类图。油种鉴别的置信水平λ_i主要受风化的影响,风化30天,任丘原油和30~#重柴油同其它13种油可分类的置信水平范围分别为:0.99939>λ_i>0.99725和0.99791>λ_i>0.99026。海面溢油鉴别结果表明,本法较指纹谱图辨识法的准确度高。

A Medol of fuzzy maximum matrix for the identification of spilled oil at sea surface is established, the concept of fuzzy area of confidence level λi for identifying types of oil was introduced. Fuzzy dynamic clustering charts of fourteen common types of oil, two types of weathered oil and oil spill at sea surface are given out. Confidence level λi was found to be greatly influenced by weathering. After 30 days weathering, confidence levels for differentiating Ren Qiu Crude oil and 35# heavy diesel oil, from other thirteen types of oil, are in the ranges of 0.99939 >λi>0.99725 and 0.99791>1,>0.99026, respectively. The method proved to be able to give more accurate result than the fingerprint recognition method.
