Research On Quality Insurance Strategy Of Prefabricated Building Engineering

Vigorously developing the prefabricated building is the only way to realize the industrialization of the building in China.Compared with the traditional cast-in-place building,the prefabricated building has considerable advantages in terms of resource conservation and time saving,but the new production method will make many original on-site construction operations in the factory.Completed,resulting in new engineering quality regulatory issues.There are big differences between the prefabricated concrete building and the cast-in-place building in terms of technical system,project implementation process,participants and supervision mode.The difference of technical system leads to different risk points,and the difference of project implementation process leads to the defects of fabricated building quality.The specific processes generated are different.The differences in participants lead to different quality accidents,and the differences in supervision modes lead to an increase in government administrative supervision,which in turn increases regulatory costs.Under the current framework of construction engineering quality and insurance-related legal system,the component factory also bears the responsibility related to the quality of the project,and there is a risk of being held accountable.At present,there is no insurance design in China's engineering quality insurance product system that can be used to transfer this risk.Component production responsibility risk and its insurance product research have important application value and practical significance.Through the research on the quality risk accident categories and risk factors of prefabricated concrete building engineering,and establishing the relationship between the quality risk characteristics of the prefabricated building engineering and the current existing engineering quality insurance product system,the construction idea of prefabricated component quality liability insurance is proposed..Finally,using game theory and computer simulation technology to analyze the strategy of the development,implementation and operation of the relevant parties(in the middle of the game),as follows:1.Through the literature research,compiled the risk list of the assembly-type construction proj ect,summed up the characteristics of the quality risk of the fabricated concrete construction project in China,and analyzed the current engineering quality insurance product system in China.The research results show that the liability risk of the transfer component factory has not been found.Insurance products.2.Constructing the quality liability insurance for prefabricated components,preliminarily defining the scope of responsibility of the insurance.Through the analysis of China's current engineering quality and insurance-related legal system,it is concluded that China has basically established the legal basis for the development and implementation of this insurance.Then use the basic theory of risk management and insurance to construct the mutual insurance mode and the ordinary insurance mode of the insurance.3.Using the cooperative game theory to explore the problem of the choice of cooperation mode between the component factory,the government and the mutual insurance agency in the mutual insurance mode of the prefabricated component quality liability insurance,and the maximization of the alliance revenue,which proves that the three have the cooperation alliance.The biggest league bonus,while the three each have the highest extra profit.4.Using game theory and computer simulation technology to study the strategy selection of the relevant participants in the development,implementation and operation of prefabricated component quality liability insurance under the general insurance mode,and conclude that in the development process,the government and insurance companies Any party adopts positive behavior(referring to the government's choice of"encourage",the insurance company chooses "development")to reach the threshold,and the evolutionary stability strategy can be obtained(encourage,development)in the time dimension;in the process of implementation,government subsidies Need to achieve a certain level of strength,the component factory will choose to insure,and the insurance company will choose to underwrite;in the operation of the insurance,the construction unit,component factory,insurance company can jointly supervise and upgrade the prefabricated components in the time dimension.The quality problem reaches a stable solution(control,active control,control).
