A NEW METHOD FOR MEASURING THE INFORMATION LEVEL OF ENVIRONMENTAL MONITORING OF CONSTRUCTION ENTERPRISES BASED ON MULTI-LEVEL GREY EVALUATION

The informatization level of environmental monitoring is the basic element to measure an enterprise's environmental management ability. However, the rationality of the existing environmental monitoring measurement indicators is poor, which results in large measurement errors. Therefore, in this paper, a method for measuring the level of environmental monitoring informatization of construction enterprises based on multi-level gray evaluation is proposed. Through the selection and quantitative analysis of the information level measurement indicators, a new information level measurement indicator system is constructed. On this basis, the linear method is used to process the measurement index system dimensionlessly, and the entropy method is selected to determine the weight of the measurement index, thereby forming the weight matrix of the measurement index. Multi-level gray evaluation theory is used to construct a measurement model. The measurement of the environmental monitoring information level of construction enterprises can be achieved by inputting the obtained measurement index values into the model. The experimental results show that, compared with the existing methods, the measurement error of the enterprise environmental monitoring informatization level of the method proposed in this paper is smaller, which fully proves that the measurement effect of the proposed method is better.
