Description

This disclosure relates to a risk assessment system, a risk assessment method, and a risk assessment program for evaluating risks at work sites. When performing work at construction sites, various risks can arise. Therefore, technologies for safety management against risks foreseeable from the work content are being considered (see, for example, Patent Document 1). In the technology disclosed in this document, the head office server outputs risk prediction information, including corrective measures to avoid risks, to the construction site client. For corrective measures determined to be implemented at the construction site, evidence information is input and stored from the construction site client. If corrective measures not implemented at the construction site are identified, information on the expected impact of non-implementation is generated, including anticipated accidents, delays in the construction schedule, cost, and insurance assessment. Furthermore, technologies to suppress workplace accidents caused by human error are also being considered (see, for example, Patent Document 2). The safety management support system disclosed in this document comprises a client to which inspection data collected via mobile phone is transferred, and a server that manages inspection data of organizations related to the site based on the accumulated inspection data. The inspection data includes information indicating high or low ratings for safety inspection items performed for the organization to which the inspected belongs. The control unit of the server categorizes the accumulated inspection data by organization. It then reports the results of statistical processing of the high/low ratings to the client. Furthermore, technologies are being considered that automatically predict accidents at construction sites and notify workers at the construction site of the prediction results (see, for example, Patent Document 3). The technology disclosed in this document predicts accident occurrences from images captured by cameras worn by workers at the construction site. If an accident is predicted, the prediction is notified to the worker. Upon notification, the worker inputs whether the prediction was correct or incorrect. Then, a model is generated using machine learning with images of the construction site as training data.
