By analyzing the module and concrete items of risks in ship pilotage, applying Grey theory analysis, brings forward the Grey Theory Analysis Model in ship pilotage risks analysis, Moreover, fuzzy function is taken in the analysis of relative risk factors, achieving the optimal relational coefficient of piloting risk factors, and finally obtaining the relational degree taxis. As indicated in the computing...
In order to promote maritime safety and reduce the loss of life and property, and achieve a safer navigation, cleaner oceans goal, this article assessed the ship traffic control safety from four aspects of the ship, namely “ships, navigation environment, people, management”. By researching the method of the safety evaluation, this article provides a valuable reference of the ship safety, and an effective...
Principal component analysis (PCA) is applied to determine the relative weights of the quantitative evaluation criteria and fuzzy analytic hierarchy process (FAHP) is applied to determine the relative weights of the qualitative evaluation criteria. Finally, the fuzzy Technique for Order Preference by Similarity to Ideal Solution is applied to rank the alternatives. Empirical results show that the...
A new smart building evacuation system consisting of intelligent integration supervisory system (IISS), smart emergency indicator boards (SEIB) and fuzzy-based approach for evacuation modeling is presented. In an emergency, the IWSS can obtain the positions of disaster area from wireless sensors. Then, the system determinates safe evacuation routes using a fuzzy system to make decisions with membership...
The security of maritime traffic is a significant part of intelligent maritime traffic. It can reduce to ship manipulation and collision avoidance by macroscopic. Eighty percents of marine accident induce by human factor from research data. So some researches about computer evaluation system inducted to ship manipulation and collision avoidance to reduce the accident of human caused. Evaluation system...
To investigate the safety of route flight in air traffic management, the collision risk is evaluated with the fuzzy sets theory. The new fuzzy evaluation method shows how the communication, navigation, surveillance, operation error, and traffic density influence the risk of collision in the parallel routes. The results demonstrate that fuzzy evaluation not only fulfill the safety assessment of separation...
