Study On Safety Control Of Assembly Building Construction Based On Case-based Reasoning

Due to the nationwide implementation of prefabricated buildings,many projects begin to use prefabricated buildings in the construction process.However,due to the high technical requirements,harsh site environment and large number of operators in the construction process,safety accidents cannot be avoided in the construction process.At present,in the process of accident prevention and control,mainly for traditional construction enterprises,there is no systematic research on the construction of prefabricated buildings.In the process of prefabricated building construction,we can borrow the previous construction experience and adopt a more information-based and scientific way to prevent and control.Based on this,this paper introduces Case-based reasoning(CBR)technology into the field of safety control of prefabricated building construction,and puts forward new methods and ideas for safety accident control of prefabricated building construction.In this paper,various influencing factors in the process of assembly construction are firstly analyzed,and some indexes are selected to establish the safety prevention and control system of assembly construction,Then a case-based reasoning method for safety control of prefabricated building construction is proposed.In the fourth chapter,the optimization model of the production function is established to optimize the investment resources of safety control in the construction of prefabricated buildings.In the process of constructing the case-based reasoning database for safety of prefabricated building construction,the composition and acquisition channels of the accident ontology are analyzed firstly,the ontology development software protege is used to create the ontology of assembled building construction safety accident,and the database is virtual for the study and use of this paper.After the case base is constructed,Manhattan formula is used to determine the similarity of feature attributes.By using the attribute weight determination method based on improved rough set,the similarity cases are determined by calculating the comprehensive similarity.According to the expert advice to adjust the output of the case and the fifth chapter of the case analysis;Finally,chapter six summarizes the main conclusions and deficiencies of this paper.In this paper,case-based reasoning technology is introduced into the field of safety control of prefabricated building construction.The existing safety control theory of prefabricated building construction is supplemented.The intelligent level of safety control of prefabricated building construction is improved,and a new method is put forward for the informatization and intelligent improvement of safety control of prefabricated building construction.
