This article focuses on fuzzy set theory as intelligent tools for navigator's decision-making to improve the safety of marine vessels in collision situations. A lot of progress has been made, especially in the field of artificial intelligence. The paper goal is to develop a decision support system based on artificial intelligence to determine a ship's trajectory in a collision situation. In this present...
The performance of a navigating officer in critical situations is uncertain and has to be considered in a probabilistic framework, since this may provide an in depth insight in the human - machine interaction. Such a systematic approach will have the objective to understand, to predict and to minimize the role of the human as a causal factor for a casualty in terms of the time sequence needed to perform...
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...
This paper describes a AIS-based model to assist the design of Ships' routeing system which provide useful insights about complex maritime transportation routes. The AIS analysis model mainly focuses on the transit traffic in the Channel. The AIS provides a method to analyze the vessel traffic density, meeting times and speed conditions in the Channels. An architecture of traffic stress model and...
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 objective of the work partially described in this paper is to reduce the situation of handicap of a person by enabling him/her to access (and/or to recover) some levels of autonomy thanks to a safe electric wheelchair. The problems concern the driving of this complex help by an operator whose capacities are reduced by the handicap in co-operation with the system. It is thus necessary to devise...
NOAA's Center for Operational Oceanographic Products and Services (CO-OPS) has developed the Physical Oceanographic Real-Time System (PORTS??) to meet the specific needs of the local maritime community by measuring, integrating, and disseminating observations of water levels, currents, salinity, wind, and bridge clearance, all of which help mariners successfully guide ships into and out of the Nation's...
The proliferation of GPS units in our life has greatly changed how people find their ways in the real world. However, overreliance on step-by-step route directions from these automated navigation systems may result in less consciously building spatial knowledge of the environment, which is critical to wayfinding. Also, GPS devices may divert people's attention from objects in the physical world to...
