基于三角模糊技术水质测试结果可信度分析

Analysis of the confidence level of COD and DO of water quality based on triangular fuzzy technology

水质化学需要量（COD）和溶解氧（DO）的测试易受各种主、客观因素影响,其测试结果是具有可信度的未确定数。为确保测试结果能正确反映所测COD和DO的实际情况,进行测试结果的可信度分析显得尤为重要;为此,将三角模糊技术应用于水质COD和DO测试结果的可信度分析,以确保测试结果的可靠性。经理论分析和实际测试表明,该法能较好地评判水中COD和DO测试结果以及结果的可信度,可推广应用于水质分析。

It is known that the measurement of COD and DO of water quality is influenced by various un-predictable factors,thus the measured results obtained were of unascertained numbers with certain confidence level.The confidence levels of COD and DO data were analyzed by the triangular fuzzy technology to assure the reliability of the measured results.It was found that the method is applicable in assessing the COD and DO data,as compared with the actual results obtained.
