Quantitative Risk Assessment (QRA) models have already been developed and used to assess various risks of road tunnels, including the societal risk and expected number of fatalities (ENF). Fire in a road tunnel is considered as the most severe disaster in that road tunnel is an enclosed space. The risk assessment for fire in road tunnels involves a number of parameters. Some of these parameters...

The objective of the paper is to propose a risk assessment model for agricultural engineering related to biosafety and security while deploying agriculture information through the latest computing and communication technologies for farmers. The earlier works concentrate much on the biological risk and agricultural risk without focusing on the effects of uncertainty in different computing and co...

There are major data gaps and uncertainties about the health risks of most potentially toxic substances. When the question in a toxic tort case is whether a particular toxic substance caused injury in a specific individual, the data gaps and uncertainties are even greater. Most disease conditions have multiple potential etiologies, and there is usually no direct evidence of which possible cause...

The assessment of risks to human health associated with exposure to oxidant air pollutants has not received adequate attention despite the recognized public health threat posed by the ubiquitous presence of these compounds in the environment. In this article, research needs and uncertainties at each of the steps in the risk assessment of oxidant air pollutants are identified: hazard identificat...

Critical environmental and human health concerns are associated with the rapidly growing fields of nanotechnology and manufactured nanomaterials (MNMs). The main risk arises from occupational exposure via chronic inhalation of nanoparticles. This research presents a chance-constrained nonlinear programming (CCNLP) optimization approach, which is developed to maximize the nanaomaterial productio...

max 150 words) Sustainable water management strategies are able to cope with uncertainties in our natural and social environment. Uncertainties in our social environment reflect changing societal perceptions on how water should be used and which objectives should be preferred. Change of these perceptions may lead to a loss of public support for strategies, forcing policy makers to take measures...

Avalanche disasters are associated with significant monetary losses. It is thus crucial that avalanche risk assessments are based on a consistent and proper assessment of the uncertainties involved in the modelling of the avalanche runout zones and the estimations of the damage potential. We link a Bayesian network (BN) to a Geographic Information System (GIS) for avalanche risk assessment in o...

A new efficient and accurate hybrid reliability method is proposed to estimate risk of an axially loaded single pile considering pile-soil interaction effect. Uncertainties associated with all the design variables are considered appropriately. It intelligently integrates the concepts of the response surface method, the finite difference method, the first-order reliability method, and an iterati...

precise identification of the risks of power plants as a part of a comprehensive safety analysis is recommended by monitoring organizations. assessment and risk management techniques in industrial activities through the use of preventive approach to identify hazards , assess and control safety - health risks unit is studied. in this study, risks and effects of abadan gas power plant were studie...

Supplier selection in supply chain is critical strategic decision for organization’s success and has attracted much attention of both academic researchers and practitioners. Supplier selection problem consists of stochastic and recognitive uncertainties. However, the requirement of large sample size and strong subject knowledge to build suitable fuzzy membership function restrict the applicabil...
