Considering the difficulty of fuzzy synthetic evaluation method in calculation of the multiple factors and ignorance of the relationship among evaluating objects, a new weight evaluation process using entropy method was introduced. This improved method for determination of weight of the evaluating indicators was applied in water quality assessment of the(More)
In order to understand the dynamic change of water quality in a specific period of time, a type of possibility transition matrix based on the theory of Markov process was established. The transition possibility with a weight to calculate the degree of absolute advancement was given based on the result of water quality evaluation. The concept of relative(More)
The fuzzy synthetic evaluation and the grey clustering method are two typical synthetic evaluation methods that can be used in water quality assessment. The difference between these two methods is the weight chosen for clustering, while the clustering processes are nearly the same. This paper considered the merits of both these two methods in designing(More)
