Safety assessment of navigation environment in waterway based on extension matter-element

Abstract

With the continuous development of maritime transportation, the flow of ships and the density of navigation are growing continuously. The traffic of ships is getting busier. As a result, the number of maritime traffic accidents is more than before, and the navigation environment is becoming more complex. Therefore, it is necessary to make a scientific and reasonable assessment. This paper identifies the factors that affect the safe navigation of channels from the perspective of navigation environment in a traditional system engineering way. In addition, this paper pursues establishing a model based on extension matter-element theory for these factors, combined with AHP method, to evaluate the safety of the traffic navigation environment of channels. 3 channels of the Ningbo Zhoushan Port are selected as an example to verify the accuracy of the model. The safety assessment results of Ningbo Zhoushan port show that they are all of low risk. Finally, it is concluded that the matter-element model is accurate for navigation environment safety assessment.
