Safety Evaluation Of Navigation Environment In Dalian Port Dayaowan Waters

Vessel traffic accident occurs mostly at the harbor waters, in addition, port construction will bring certain influence to ship navigation around the harbor, so the port navigation safety evaluation is necessary. Dayaowan Port Area of Dalian Port is a relatively busy port, the traffic is more. For the safety of the port, the judgment is mostly emotional, this article is based on this, will give a quantitative evaluation of the safety of navigation, for providing the reference for the follow-up development planning of port.After analyzing on a variety of navigation safety evaluation method, this article will use fuzzy comprehensive evaluation in Fuzzy Mathematics to establish the navigation safety evaluation model. In this article, firstly, give a brief introduction of fuzzy comprehensive evaluation, and process the experts questionnaire data, then, introduce each impact factor and establish the corresponding membership function; Secondly, integrate these factors together to establish a fuzzy comprehensive evaluation model; thirdly, introduce the basic information of Dayaowan Port Area of Dalian Port, in accordance with the relevant theory of AHP, respectively establish factor set, evaluation set, weight set; Finally evaluate using the established Port navigable waters navigation safety fuzzy comprehensive evaluation model, then get the evaluation results.This study provides a theoretical and practical reference for safety operation of Dayaowan waters of Dalian port.
