This paper classified, extracted and characterized the causes of accidents based on accident statistics of chemical enterprises in Jiangsu Province from 2015 to 2019. The internal relationship between the accident result and various causes is analyzed from the aspects of human, machine, material, method, ring and pipe; and using the analytic hierarchy process to establish the comprehensive evaluation index system of the accident, which was applied to predict the accident probability of chemical enterprise. The probability of production safety accident in a chemical enterprise is predicted by using this method, and the probability of the accident is at level of "more likely to happen". The example showed that the analytic hierarchy process has strong operability and good effect, and can be used to predict the accident risk of chemical enterprises. causes and can realize the accident probability prediction of chemical enterprises.

On the basis of literature survey, this paper combines qualitative research with quantitative research to evaluate the influencing factors of expressway project risk under PPP mode. This paper starts from three parts:Firstly, starting from the current situation of expressway construction projects at home and abroad through the analysis of the advantages and disadvantages of PPP mode and three characteristics, the necessity and importance of project risk management under PPP mode are obtained. Secondly, the paper elaborates the risk of PPP project of expressway identifies the corresponding risk, and initially determines the three major factors affecting the risk of expressway project under PPP mode. Finally, according to expert judgment, the most critical factor is determined and a scientific, reasonable and effective risk factor evaluation index system is established. The index system includes three first-level indicators and six second-level indicators. On this basis, the judgment matrix is constructed by using the analytic hierarchy process, so as to form the influencing factor model. Finally, taking Fuling-Fengdu Expressway in Chongqing as an example, this paper uses the analytic hierarchy process (AHP) to carry out an empirical study on the model, in order to determine the importance of different risk factors.

Objectives: To identify early suicide risk signs on depressive subjects, so that specialized care can be provided. Various studies have focused on studying expressions on social networks, where users pour their emotions, to determine if they show signs of depression or not. However, they have neglected the quantification of the risk of committing suicide. Therefore, this article proposes a new index for identifying suicide risk in Mexico. Methodology: The proposal index is constructed through opinion mining using Twitter and the Analytic Hierarchy Process. Contribution: Using R statistical package, a study is presented considering real data, making a classification of people according to the obtained index and using information from psychologists. The proposed methodology represents an innovative prevention alternative for suicide.
