Construction of Evaluation Model of College Students'Laboratory Safety Consciousness
In order to prevent laboratory safety accidents and improve college students'laboratory safety awareness,this paper establishes an evaluation system of college students'laboratory safety awareness by using the subjective and objective combination of analytic hierarchy process and entropy weight method(AHP-EWM),selects evaluation indexes whose cumulative contribution rates are all more than 95％after PC A processing,optimizes the CS algorithm,and establishes the PCA-CS-SVM evaluation model of college students'laboratory safety awareness.The verification results show that compared with PCA-LS-SVM and PCA-GA-SVM models,the error between the predicted value and the actual value of PCA-GA-SVM model is small,and the evaluation level is consistent with the actual value.It has high accuracy and reliability.It can be used for the evaluation of college students'laboratory safety awareness.
