Research On The Evaluation Of University Campus Security Consciousness Based On AHP-FCE-SVM

With the development of the economy,the safety of students in colleges and universities has been concerned by the society.Because campus security is complex,and security issues are affected by many factors,it is meaningful to study campus security awareness in the context of complex systems.In order to reduce the occurrence of campus safety accidents and keep colleges and universities at a higher level,it is particularly important to analyze the rating levels of college safety awareness.As the security awareness of colleges and universities is a vague concept,people are the main research target of security issues in colleges and universities,and their security awareness determines the safety behavior.In this dissertation,Analytic Hierarchy Process(AHP)and Fuzzy Comprehensive Evaluation(FCE)are combined to evaluate the level of campus safety awareness.First of all,this dissertation issued questionnaires to three groups of students,frontline teachers and university administrators in a certain engineering college to extract the general characteristics of campus safety awareness.Secondly,based on the complex system theory,the first-level evaluation index of safety awareness in colleges and universities is constructed,and an evaluation system including 4 second-level indicators and 16 third-level indicators of students’ own safety awareness,campus environment,social environment,and campus management is constructed.Finally,the safety awareness levels of the overall,students,front-line teachers,and campus administrators are compared.The results show that the overall campus safety awareness level is "average." The safety awareness level of students is "average",and the safety awareness level of frontline teachers and campus administrators is "good".The social environment and campus management factors have higher weights,while the students’ own safety awareness and campus environment factors have lower weights.In the evaluation index,the weight of the secondary evaluation index campus environment factor is low.Based on this,this dissertation further analyzes the campus safety food factor.The improved AHP-FCE is used to analyze the food safety level of campus.First of all,this dissertation uses the form of questionnaire to issue questionnaires to students of a certain engineering college to improve the evaluation indicators,and secondly,add sub-factor layers on the basis of decision-making layers.Construct a first-level evaluation index for campus food safety,including 4 secondlevel standards for employee personal hygiene,restaurant hygiene,food quality and service quality,12 third-level indicators and 4 fourth-level indicators.Finally,the food safety evaluation result was "very good".Support vector machine(Support Vector Machine,SVM)method is used to verify the AHP-FCE campus security awareness evaluation model,and the parameters are optimized by cross-validation method and particle swarm algorithm respectively.The simulation shows that the safety awareness of colleges and universities is "general".The comparative analysis of the state obtained by AHP-FCE-SVM and AHP-FCE verifies that the campus safety awareness evaluation model has application value and provides a reference for future campus awareness evaluation.
