Research On Stakeholder-based Ontology Modeling Of Construction Quality

The construction industry plays an important role in our national economy for a long time.Well construction quality is of great significance to the national economy,so the control and management of construction quality is also an important topic in the field.In recent years,with the gradual expansion of the scale of construction projects,engineering accidents also occur frequently,which has gradually improved the requirements of quality management.Due to the particularity of construction engineering,there are a dozen or more cooperative units participating in the construction engineering,many of which play different roles in the construction quality management.From the perspective of the whole cycle of the construction project,the construction stage,as a key stage of the construction quality management,should be paid special attention to.Therefore,in the construction site,it is very important for the stakeholders to participate in the quality management in coordination,including on-site labor,supervision,management and other functions.However,at present,the construction quality management is still dominated by human resources and lacks effective intelligent management means.Therefore,from the perspective of stakeholders,this paper uses ontology model to establish a standardized knowledge system in the field to control the behavior of stakeholders and improve the construction quality management system.The main research contents include the following aspects1)Domain knowledge acquisition and analysis,through the network,books and other ways to consult,consult and practice to obtain necessary domain knowledge.Through the preprocessing of artificial preliminary knowledge,it is necessary to prepare for the establishment of owl standardized documents.2)Ontology model is established to express the relationship between stakeholders and building information in a unified paradigm.First of all,the research analyzes and summarizes the research status of domestic and foreign scholars in the field,formulates the basic idea of this research,uses "Seven Steps" to determine the concept and the relationship between concepts in Protege,and gradually improves the ontology model and passes the consistency test.3)Establish SWRL rule base to realize the reasoning function of ontology.This paper introduces the reasoning mechanism and reasoning environment based on description logic in the research,and compiles eight reasoning rules about several common wrong construction methods in the construction of concrete cast-in-place piles.4)Case modeling and validation.On the basis of OWL ontology knowledge base and SWRL rule base,the pile foundation construction process of a high-rise residential building is verified.The results show that the model can basically identify the violations in the case and feed back the responsible stakeholders to the user interface.The results show that:1)the ontology passes the consistency test;2)the inference results basically achieve the expectations.In the case environment given by the study,the inference system can effectively identify illegal and legal behaviors.It can be seen that the model can effectively use the ontology knowledge base to identify the behavior of the stakeholders on the site and feed back the violations to the users,and can provide the relevant responsible subjects with management and decision-making assistance services.Compared with the current human resources,the system has the advantages of integrity,objectivity and accuracy of management and control in the construction quality management,which has a certain practical significance for improving the construction quality management...
