Debris flow is one of the usual mountain geological disasters, and it is significant to assess and forecast its risk degree. The paper bases on statistical analysis of influence factors of debris flow risk degree, establishing 15 indexes to accurately assess debris flow risk degree. Furthermore, the evaluation index system is constructed by using analytic hierarchy process. And after combining the linkages between indexes, calculating each weight, and amending repeatedly with examples, finally the comprehensive mathematical evaluation on risk of debris flow is set up.

The threaten degree assessment of oil spill accidents is an important content of the emergency decision. On the basis of reference to the domestic and overseas oil spill accident evaluation, this paper fully considered the sources of oil spill, receptors, as well as the influence factors which all affect the threaten level of oil spill accidents, and a comprehensive and clear hierarchy evaluation index system was set up. Finally,analytic hierarchy process (AHP) was used to assign index weights and quantitatively determine the threat level.

Prefabricated Building

Prefabricated building is an efficient building mode. Compared with the traditional building mode, the prefabricated building has advantages of less pollution, high construction efficiency, being more labor-saving, and economy, which is in line with China’s sustainable development strategy. This paper proposes a supplier selection evaluation model based on the mechanism equation model (SEM) and intuitionistic fuzzy analytic hierarchy process (IFAHP). Based on a detailed literature review, 300 structured questionnaires were distributed to the relevant enterprises, and an evaluation index system of prefabricated building element suppliers was built. With the fitting and modification process using a structural equation model, and assist of a path factor, an evaluation index system for evaluating the prefabricated building element suppliers was finally obtained. Finally, the intuitionistic fuzzy analytic hierarchy process was used to establish a selection model of prefabricated element suppliers, and the prefabricated element suppliers of Shuangyashan prefabricated construction projects were analyzed as a case study. The results show that the following factors have the most significant impact on supplier selection (from high to low): quality, economy, long-term cooperation, after-sales, and transportation. This study had a comprehensive consideration of the influencing factors existing in the whole selection process and should provide a valuable reference for the sustainable development of prefabricated construction engineering.

The double development of urbanization and motorization has made the traffic demand of our country grow rapidly and diversified. the improvement of urban traffic has become an important condition for the sustainable development of the city. Based on the analytic hierarchy process (AHP), this paper establishes the evaluation index system of urban traffic improvement by comparing the importance of indexing by experts. It is found that improvement of road network, optimization of public traffic and improvement of intersection are the most important in urban traffic improvement. the intersection of the most important level of service. By using qualitative and quantitative methods, the Likert scale was used to classify the results and the four-quadrant method was used to analyze the urban traffic improvement evaluation index system.

Improved Analytic Hierarchy Process

As the tunnel project has the characteristics of concealment, complexity, uncertainty and the larger investment risk, whose insidious danger is outstanding especially in the construction process. It is important for the safety of the construction process to determine the potential risk and minimize the risk using reasonable methods. Based on the experts investigation, 3-hierarchy and eighteen factors’ evaluation index system of risk assessment is established through the improved analytic hierarchy process. The results show that this method is reasonable and can greatly reduce graded difficulties.

Due to the high risk of construction sites, it is necessary to make safety risk evaluation. With the synthetic consideration of the complexity and uncertainty of construction sites, a comprehensive evaluation index system with two levels has been based on the emphases and difficulties of the current safety work in construction industry; the index system includes civilized construction site, management of machinery, equipment, materials, occupation health protection, and the subpackage management, such as 6 one-level evaluation indexes, inspection system of safety risk, safety awareness education, and prevention and control of occupation disease, such as 33 two-level evaluation indexes. The research takes “No. A residential building and other 8 projects” as the empirical analysis object, with the weights of the first indexes and second indexes being calculated by the analytic hierarchy process (AHP) and the information entropy, and applies the unascertained measure to comprehensively evaluate the safety risk of the construction project. The overall score of the project is 6.4475, the evaluation result is good, which is consistent with the actual situation, and the feasibility and effectiveness of the evaluation index system and evaluation model are verified, which provides a reference for safety risk management in the construction stage of construction projects.

Chongqing International Marathon event is one of the top marathon events in China. Under the background of the new era, constructing a scientific and reasonable marathon evaluation system plays an important role in the development of this event. In this study, literature method, field investigation method, Delphi method, interview method, analytic hierarchy process, and other methods are used. And it includes 5 primary indicators, 13 secondary indicators, and 58 tertiary indicators. What is more, AHP is used to determine the weight of indicators at each level. This evaluation system can help the race-organizing committee more scientifically understand this event and lay a solid foundation for finally building an excellent brand event.
