The WiSafeCar (Wireless Traffic Safety Network Between Cars) project aims at creating a comprehensive wireless communication and service platform targeting vehicular networks, striving to reduce accidents and traffic congestion. Within the frame of this project, a dynamic carpooling transport system was designed, reacting in real time to events and user transport requests. In order to allow this system...
Protecting the public from an airborne toxic-gas release requires that appropriate protective actions be selected quickly. When the leakage of toxic-gas happening, the emergency responders must take protective action, namely evacuation or shelter-in-place. But the occurring and developing process of the leakage of toxic-gas are much uncertain, so the decision makers should manage the scene and deicide...
The chemical industry park is the product that the modern chemical industry adapts to the resources or raw materials conversion, complies with the international, intensive, large-scale operation, the development trend for the optimization and the most efficiency. It is the leading direction for achieving the long-term development of the chemical industry. With the rapid economic development and boom...
There has been growing academic and industry interest in the behavioral animation of autonomous actors in virtual worlds. However, it remains a considerable challenge to automatically generate complicated interactions between multiple actors in a customizable way with minimal user specification. In this paper, we propose a behavior authoring framework which provides the user with complete control...
Safety management of coal mine is an important part of enterprise management, it is also the important guarantee to achieve work safety. The ERP system of coal mine safety is an advanced, dynamic safety management mode, it can improve the safety management level to implement ERP system, prevent and reduce accidents, too. The paper describes the management ideas and models of ERP system, and applies...
In this paper, an approach to solve a flow assignment problem is proposed assuming known the whole trip planning of the fleets. The objective is to minimize both the risk of the network associated to the DG transport flow and the variance of the assigned delivery planning in respect to the expected one. Different simulation tests have been performed to evaluate the goodness of the proposed model,...
In the last decade, reliability improvement warranties (RIW) became increasingly popular with customers of machine tool manufacturers especially in the automotive industry. These RIWs include long term warranties (for up to 10 years) for reliability figures like the Mean Time Between Failure (MTBF). The long warranty period, the stochastic nature of reliability, unknown operational conditions and...
The rapid development of economy promotes the acceleration of urbanization, but in many cities, especially in the medium-sized city, traffic problem has become the bottleneck of restricting the development.This paper analyses the causes of the medium-sized city traffic accidents and existing problems of the road planning, construction, road traffic management ,and proposed herein with measures for...
Regional environmental risk assessment and management mainly focused on middle-scale. By analyzing the formation mechanism of regional environmental risk, the scale and intensity of regional environmental risk can be assessed on the base of superposing different risks, which can provide technical support to make decisions for regional environmental risk management. Considering the relationship between...
Autonomous systems are often needed to perform tasks in complex and dynamic environments. For this class of systems, traditional safety assuring methods are not satisfying due to the unknown effects of the interacting system with an open environment. Briefly speaking: What is not known during the development phase, can not be adequately considered. In order to realize a more flexible safety analysis,...
In recent years the engineering accidents, especially those occurred to large-scale public projects were paid more and more attention by engineers and even the normal public. The large-scale public projects involved such numbers of participants and complicated procedures, which challenge to the traditional project security management. There is should be anew method to do with the modern engineering's...
Expressway emergency rescue system is important for the expressway safety management.Through analyzing the traffic incident on expressway; this paper proposed a model based on respond time for the planning of expressway emergency rescue station. We analyze the characteristic of each expressway section by the historical statistics of traffic incidents, such as the number of incidents, casualties, property...
After the occurrence of grid emergency, fast and accurate evaluation of harmful levels of the incident and identification of disaster-level are the basis for activate contingency plans, reasonable allocation of resources and thus crisis management. Combined with the practical, the paper sets up grading evaluation index system of power emergency from the power grid losses, the user lossed and accident...
Coastal engineering planning (CEP) must deal with routine and non-routine hazardous conditions, particularly from cumulative hazards or from events with low probability but large consequences. We develop and exemplify a risk-based assessment to support coastal engineering planning, which is consistent with the precautionary principle, and provides scientific support for decision-making processes....
The risk of chemical site imposes on nearby vulnerabilities is of great concern and remains undefined. Risk severity index is devised to illustrate the risk levels in a simple and understandable way, with SLAB modeling the exposure of vaporizable substances. Risk and vulnerability mapping are both presented on the platform of GIS, and the distribution of vulnerability in different risk leveled areas...
A comprehensive evaluation index system with a complex structure and an uneven index distribution is presented according to the characteristics of railway emergency plans. In view of the impacts and errors induced by the features of the comprehensive evaluation index system with the traditional analytic hierarchy process (AHP) method, the Improved AHP method is brought forward. The hierarchical structure...
Based on detailed analysis of maritime emergency plans, maritime emergency evaluation index system is established. The index system is characterized by the complicated hierarchy structure and multiple index attributes, the improved fuzzy synthesize evaluation method is used to evaluate the maritime emergency plans comprehensively. Qualitative evaluation and quantitative evaluation are combined, and...
It was an important to improve urban transportation management level by carrying out urban transportation management planning. According to the characteristics of urban transportation management planning, the evaluation model of urban transportation management planning project was studied based on fuzzy theory. First, the 14 evaluation index of urban transportation management planning project was...
Public transport is one of most complicated systems in a modern city. Based on the grey system theory, a grey relational assessment model on service quality of urban public transport is put forward. On the Basis of above, this method is applied to evaluate the service quality of public transport in one northern city.
This paper demonstrates a fuzzy goal programming (FGP) procedure for modeling and solving patrol manpower deployment problems of Metropolitan cities to deterring traffic violations and accidents and thereby reducing accident rate in a traffic control planning horizon. In the proposed approach, the different structural constraints and various relationships involved with patrol manpower deployment problem...
