“…Due to its systematic characteristics, it is particularly prominent in the field of risk research, which needs multi-agent collaboration. For example, the WSR framework is used for risk control in the area of nuclear security (40), cost risks in the field of construction (41), and security risks in the field of enterprise management and control (42). However, it is rarely used in the area of public health network opinion, and there are many topics involved in this area.…”

ObjectiveTo obtain the influencing factors of public opinion reactions and to construct a basic framework of the factors causing the occurrence of online public opinion in the epidemic area.MethodsThe hot news comments on microblogs during the epidemic in Shanghai were collected and analyzed with qualitative analysis, grounded theory, and the “Wuli-Shili-Renli” (WSR) methodology as an auxiliary method.Results(1) Three core categories of the Wuli system, the Shili system, and the Renli system, 15 main categories, and 86 categories that influence the development of network public opinion are obtained. (2) WSR Elements Framework Of Network Public Opinion (WSR-EFONPO) is established. (3) The WSR-EFONPO is explained.ConclusionThe framework of factors for the occurrence of network public opinion is proposed, and the development process of network public opinion under COVID-19 is sorted out, which is of great theoretical value in guiding the public in the epidemic area to form reasonable behavior.

“…Considering the interconnection between risk factors and the comprehensive impact on the project, determining the risk level and comparing it with the benchmark level to determine whether the risk is within an acceptable range. The risk assessment is here [23][24][25]: determine the baseline level -determine the risk level -compare -determine whether it is acceptable. Compared with risk analysis, which only considers the influence of a single factor, risk assessment pays more attention to the system and the overall situation.…”

Based on the analysis of the risk occurrence path of prefabricated buildings, this paper identifies the key factors of construction risk, expounds the risk occurrence mechanism of construction, and builds a risk assessment model of construction based on Monte Carlo visual recognition neural network. At present, with the rapid development of social economy, various materials have been excavated and put into use in the field of construction. In addition contemporary problems with materials pollution have become increasingly prominent, especially in the construction industry. People have begun to pursue a more comfortable and environmentally friendly housing environment. Prefabricated buildings have their unique advantages in the modernization of such a construction industry. developed against the background. Due to the change in the construction mode, the quality of design and construction personnel, as well as the existing technical capabilities and supporting facilities have not reached the due level, and the resulting safety problems need to be solved urgently. There are many risk factors in the implementation process, and the risks The probability and consequences are difficult to accurately judge. In this paper, through the identification of risks in prefabricated building projects, a risk index evaluation system is established, and the risk of prefabricated buildings is evaluated and studied risk evaluation, the influence of human subjectivity can be overcome, and the evaluation results can be It is more accurate and reasonable, and finally achieves the purpose of risk management and control, and puts forward corresponding measures according to the evaluation results, which provides new ideas and methods for the risk assessment and model optimization research of prefabricated buildings.

“…Since the General Office of the State Council issued a policy on vigorously developing PBPs in 2016, China's PBPs have developed rapidly. The PBPs are very attractive to China's construction industry [14] because they conform to the construction concept of "sustainable green development" [35]. With the increasing demand for PBPs in China's construction industry, the central government has promulgated many policies to promote the development of PBPs [34].…”

“…Li et al [30] constructed a risk identification feedback graph and a risk flow chart using the system dynamics method to comprehensively identify investment risks that projects in China may face, and identify four key risk factors. Ye et al [35] established a dynamic evolution model of PBP cost risk based on the dynamic Bayesian network (DBN) and studied the construction cost risk evolution and transfer mechanism of PBPs. Rose [27] used an interactive research approach to conduct a case study of a Swedish PBP and proposed solutions for three major risks.…”

Risk Network Evaluation of Prefabricated Building Projects in Underdeveloped Areas: A Case Study in Qinghai

2022

View full text Add to dashboard Cite

Prefabricated building projects (PBPs) face more risks than traditional construction projects, especially in underdeveloped areas. This study takes Qinghai Province as a study case. Social network analysis (SNA) is adopted to develop a risk network of PBPs, and nine core risk factors and five key risk relationships are identified. Risk effect detection reveals the effectiveness of risk response strategies. The research shows that PBPs in underdeveloped areas are still in the early stage of development, and developers generally lack a leading role. There are prominent problems in the design stage of PBPs, so the stakeholders pay special attention to them. In underdeveloped regions, the development of PBPs must rely on the strong promotion of the government. Limited by natural and economic conditions, the market mechanism of PBPs in underdeveloped areas is not perfect, and policy regulation greatly affects the spread of the risk network. Therefore, local governments need to actively introduce corresponding supportive policies and mobilize the enthusiasm of stakeholders. This is the first study to consider the risk within the life cycle of PBPs in underdeveloped plateau areas. This study expands the research system of risk management of PBPs and provides valuable risk response strategies for the stakeholders.
