An Ontology Model to Facilitate Sharing Risk Information and Analysis in Construction Projects
Construction projects face a high level of dynamic and various risks. Risks may result in deviation from pre-determined construction project’ objectives. Systematic risk analysis is critical for sharing risk information related to decision making thus effective risk management. In this study, a Risk Analysis Ontology RA-Onto is proposed that may facilitates development of databases and information sharing for risk analysis. A detailed review of the literature on construction risks has been carried out to development of the RA-Onto that organizes risk knowledge into unified classes together with corresponding properties and relations. Ontology is evaluated theoretically and practically by using five case studies. RA-Onto could be used to support decision-making during the risk management. It enables companies to corporate memories, create databases, and develop a model to support the systematic risk analysis for better decision making.
