“…However, how to better balance the budget shortfall and maintenance benefits has been continuously explored, and there are a number of excellent research results, such as: a stochastic optimization model applied from two perspectives: the number of good pavement segments and the effect of global warming [4]; a multi-stage stochastic mixed integer planning model that takes into account both budget and pavement deterioration uncertainties [5]; an integer linear programming method using pavement performance as an indicator [6]; MADA using the best-worst method (BWM) and gray correlation analysis (GRA) [7]; combining dynamic programming with traditional genetic algorithms for budget allocation planning of roads [8]; designing models that use a multi-classification machine learning algorithm to predict the type of pavement treatment [9]; maintenance planning based on funding and resources, considering risks and failures [10]; a multi-stage stochastic planning approach that considers parameter uncertainty in pavement maintenance [11] etc. However, the above models consider fewer factors and are less reliable.…”

By choosing the right pavement maintenance plan, we can reduce resource utilization, reduce environmental pollution, and extend road life, which is important for improving social sustainability. At present, the selection of road maintenance programs mostly adopts multiple attribute decision-making (MADA), in particular, the analytic hierarchy process (AHP) is often used. However, this method needs to use expert scoring data, which leads to strong subjectivity and poor reliability. Therefore, it reduces the science of road maintenance scheme selection. In order to reduce the subjectivity of the score and obtain a more suitable road maintenance scheme, this paper applies a multi-criteria decision-making method that characterizes attribute information by triangular fuzzy numbers (TFN) in the discrete decision space. Firstly, we invite experts to score the importance of the selection of pavement preventive maintenance technical solutions with respect to the indicators affecting the selection of solutions. Secondly, the two indicators of similarity and reliability are used to quantitatively evaluate the indicators and programs, respectively. Finally, we compare the weighted programs according to the overall possibility degree of each program. In actual cases, the overall possibility degree of each scheme obtained by this method is 1.0002–0.0477, and the optimal solution is fog sealing technology. The decision-making model applied in this paper can be considered in multiple dimensions, which can scientifically reduce the subjectivity of expert scoring. The best maintenance plan can also be quickly obtained through the simple calculation method in this paper.

“…Fault tree analysis (FTA) is a special kind of causality diagram [16], which describes the causal relationship between events in a system using logic gates (and gates, or gates, etc.) and prescribed symbols, where the input events of the logic gates are the causes and the output events are the effects [17][18]. Fault tree analysis (FTA) is a class of causal linkage diagrams that use logic gates such as and gates, or gates, etc., and specified symbols to depict the association of all the events in a system; the fault tree starts from an undesired initial event and leads to a series of outcomes based on possible system events [19][20].…”

In the contemporary post-truth era, there is a marked increase in the individual’s need for emotional expression and self-awareness. This paper introduces and defines the concept of “Fetish Opposition” through etymological research. Employing fault tree analysis, this study analyzes the risk identification and structural importance of “Fetish Opposition” in the context of “Public Security Prohibition” enforced by police departments. This is approached from the perspective of security system engineering, aiming to elucidate the underlying issues and delineate strategies to mitigate the phenomenon of “anti-public security.” This exploration seeks to provide theoretical guidance for enhancing the effectiveness of public security organs. The findings indicate that “lack of law enforcement transparency” holds structural importance of 0.186 within the fault tree of “Fetish Opposition,” making it the most significant factor affecting the entire system. Based on this insight, the police public relations department could develop targeted strategies to prevent such situations, thereby also opening new avenues for research in social psychology and the stabilization of police-community relations.
