This paper deals with research of safety performance predictions to allow improved risk control in military. Safety performance is identified as appropriate tool to establish system-wide information on safety which can serve the decision making process on how to manage safety. The information contributes to better understanding of behavioural patterns in the controlled system and the ability to foresee...
Various approaches and perspectives have been presented in safety analysis during the last decade, but when some continuous outcome variables take on values within a bounded interval, the conventional statistical methods may be inadequate, and frequency distributions of bounded outcomes cannot be used to handle it appropriately. Therefore, in this paper, a logistic quantile regression (QR) model is...
The water transportation plays an important role in the world recently. However, the maritime accidents are attracting public attention. The way to improve safety of navigation has become a prior task for the operations. The trajectory is useful to analyze the features of the traffic flow and helpful to simulate traffic flows. Therefore, to explore the law of navigation in curving waterway and the...
This text applies fuzzy influence diagram theory to forecast the freight channel traffic flow in Emeishan. According to fuzzy influence diagram theory, many factors which affect the traffic flow were selected. The model of the traffic flow forecast and assessment model was put forward based on fuzzy influence diagram theory. After we apply this method in the practice, this method of the traffic flow...
Traditional risk analyses approach for ship collision generally calculates the possibility of ship collision with historical data, mathematical models and consultation of the experts, which only evaluates the present risk level. However, it is obvious that the outcome of the analyses is definitely not appropriate to describe the future of the studied area. This article introduces a new risk analysis...
With the rapid development of underground metropolitan transportation, the problem of safety risks, especially the fire risks, have always been accorded great attention by researchers and practitioners. In order to reduce the uncertainty of fire risks in underground metropolitan transportation, the main objective of this paper is to devise a proactive approach to dynamically predict and control conditions...
