Problems solved by technology
In such a complex working environment, there are many risk factors and hidden dangers
Therefore, the risk assessment of shipbuilding is indispensable. It is necessary to judge the safety level through risk assessment, systematically and objectively evaluate the safety status of the shipyard manufacturing site, timely and accurately diagnose the safety hazards of on-site operations and make rectifications. At present, shipbuilding enterprises try to Try to rely on artificial inspection and scoring to judge safety, which leads to a certain degree of subjectivity in the judgment, so the judgment is not accurate and reliable enough

The invention provides a ship manufacturing operation safety evaluation system construction method based on an extension cloud model. The ship manufacturing operation safety evaluation system construction method comprises the following steps: collecting resource data as sample data; recognizing and sorting the resource data, analyzing a logical relationship between the resource data and forming a category system of a research object; performing quality analysis on the data in the category system to obtain a shipbuilding enterprise safety risk evaluation system; screening data in the ship manufacturing enterprise safety risk evaluation system to finally obtain a simplified comprehensive index system, and constructing an extension cloud model of operation site safety risk comprehensive evaluation; and calculating a comprehensive evaluation matrix and a comprehensive weight vector, combining the comprehensive evaluation matrix and the comprehensive weight vector to obtain a comprehensive evaluation vector, and evaluating the safety level through the comprehensive evaluation vector. According to the method, enterprise field operation safety data is collected, an accurate and reliable safety evaluation system is established, and construction potential safety hazards are diagnosed timely and accurately.
Description
technical field [0001] The invention relates to the technical field of safety evaluation systems, in particular to a construction method of a shipbuilding operation safety evaluation system based on an extension cloud model. Background technique [0002] The shipbuilding enterprise is a heavy industry. Usually, the shipyard has a very large scale, tens of thousands of employees, towering cranes everywhere, various special vehicles, and sparks caused by electric welding. In such a complex operating environment, there are many risk factors and hidden dangers. Therefore, the risk assessment of shipbuilding is indispensable. It is necessary to judge the safety level through risk assessment, systematically and objectively evaluate the safety status of the shipyard manufacturing site, timely and accurately diagnose the safety hazards of on-site operations and make rectifications. At present, shipbuilding enterprises try to Try to rely on artificial inspection and scoring to judge...
