Trend assessment of safety management status described the variation of the safe state during the process of construction, and it is an early warning of safe accidents to some extent. So the study of it is becoming a burning question. Aim at the uncertainty and the dynamic characteristics of the system; the trend assessment model of bridge construction safety management status has been set up using the theory set-pair analysis and Markov chain. The application results show that this model can predict the safety management status of the next and final stage relatively accurately, and it can play a guiding role in preventing safety accidents.

The quality of road and bridge engineering is directly related to the safety of the transportation industry. In the construction of highway bridges, it is particularly important to strictly control the construction quality. Combining the analytic hierarchy process and the fuzzy comprehensive evaluation method, the AHP-fuzzy comprehensive evaluation method is used to obtain the current road bridge construction safety risk level. According to the different risk levels, effective measures should be taken to avoid unsafe accidents. On this basis, historical risk cases can be analyzed to find problems in the safety assessment of highways and bridges, and effective construction safety management and control measures can be put forward to ensure the vigorous development of my country’s highway and bridge industry.

Comprehensive Evaluation Model

Evaluating safety culture of coal mining enterprises can promote effectively their safety management. This paper introduces an improved fuzzy comprehensive evaluation model specially designed for the safety culture evaluation of coal mining enterprises. Evaluation index system which is comprised of 4 first-layer indexes and 15 second-layer indexes is established based on ANP, and then the weights of indexes are calculated by Super Decisions software. The FCE model for safety culture of coal mining enterprises is built to assess accurately the safety culture of coal mining enterprise S based on the indexes system. The evaluation results indicate that the evaluative value of enterprises S is “71.979”, which stays in the “generally good” level. Thus, enterprises S should implement timely rectification measures to reach the “better” or “very good” level. The method of fuzzy comprehensive evaluation is a practical and efficient way to assess safety culture of coal mining enterprises.

Safety Accident

For many risk events in civil engineering construction have the property of “the connotation is explicit, the extension is vague”, the influencing factors of civil engineering construction safety accident are measured with the membership degree in fuzzy mathematics. The weight of indexes of various influencing factors is calculated with the method of analytic hierarchy process, thus a fuzzy comprehensive evaluation model for civil engineering safety accident is given, which is a new qualitative and quantitative solution method and makes it become possible for the early warning of civil engineering construction safety accident. In the end, it is demonstrated with an actual example for the availability of the model in the early warning.

Severe Problem

Aiming at the increasingly severe problem of University Campus Safety, this paper uses AHP based on the analysis and study of daily management of universities to establish five indexes as first criteria layer, which are school safety management, the management of counselor, the family factor, the factor of college student, social safety environment, and nineteen safety evaluation indexes as second criteria layer. So the Stratified hierarchical structure model can be built. As a result the fuzzy comprehensive evaluation model can be established. More over this paper applies MATLAB to solve the calculation of the model. Through the empirical analysis the evaluation result is consistent with the actual situation. Finally the result shows that the model have an important guiding significance to safety management work in colleges and universities, besides it is feasibility and operability.

Based on the principle of “4M1E” in management, the article first built a reasonable evaluation index system of construction safety management of high-rise buildings, and then put forward a grey hierarchy evaluation model using the combination of the AHP method and the grey appraisal theory. The results of case verification show that this method can assign the importance priority sequence of safety management measures, and reduce the subjectivity of evaluation, which is significant for the improvement of safety level in the future.

According to the situation of high frequent accidents and supervision difficulties in highway construction project. The fuzzy evaluation model for the affecting factors of highway construction accidents was established. Through safety analysis on many accidents, it was considered that highway construction accidents were commonly affected by workers’ unsafe behavior, unsafe condition, environmental risk and management. Then the weight of relative factors were determined. Finally the highway construction safety management evaluation was built. It shows that this method is reasonable and handled, which provides a good thought for the scientific, quantitative and available evaluation of highway construction safety management.
