In today’s business environment, harsher and more frequent natural and man-made disasters make supply chains more vulnerable. Supply chain disruptions now seem to occur more frequently and with more serious consequences. During and after supply chain disruptions, companies may lose revenue and incur high recovery costs. If supply chain managers were more capable of measuring and managing supply...

In this paper we present a novel approach of using mathematical models and stochastic simulations to guide and inform security investment and policy change decisions. In particular, we investigate vulnerability management policies, and explore how effective standard patch management and emergency escalation based policies are, and how they can be combined with earlier, pre-patch mitigation meas...

Application compartmentalisation decomposes software applications into sandboxed components, each delegated only the rights it requires to operate. Compartmentalisation is seeing increased deployment in vulnerability mitigation, motivated informally by appeal to the principle of least privilege. Drawing a comparison with capability systems, we consider how a distributed system interpretation su...

Over the past few decades, efforts to assess and understand the socio-economic factors that contribute to a population’s vulnerability to meteorological hazards have increased. It has become more common to use quantitative methods to approach this issue in State Hazard Mitigation Plans written by state emergency management agencies (e.g Odeh 2002, Simpson and Human 2008). Additionally, a report...

A major hazard during the eruption of explosive volcanoes is the formation of pyroclastic density currents (PDCs). Casualties and physical building damage from PDCs are caused by the temperature, pressure, and particle load of the flow. This paper examines the vulnerability of buildings and occupants to the forces imposed by PDCs along with associated infiltration of PDC particle and gas mixtur...

The role climate change may play in altering human health, particularly in the emergence and spread of diseases, is an evolving area of research. It is important to understand this relationship because it will compound the already significant burden of diseases on national economies and public health. Authorities need to be able to assess, anticipate, and monitor human health vulnerability to c...

Mitigation and adaptation have become two main strategies that governments around the world are focusing on in response to the threat of global climate change. In August 2009, Typhoon Morakot heavily damaged the central and southern parts of Taiwan, causing irreversible damage to the environment, especially in the mountain areas. In this study, the goal is to attain sustainable reservoir manage...

How (in)formal should the classic expression describing risk as product of hazard, exposure, and vulnerability be considered? What would most complete way to describe process mitigation? These are questions we try answer here, using a formal, mathematically sound yet abstract description vulnerability, risk. We highlight elements that can affected for purpose mitigation show how this improve qu...

this paper presents a new control method for a three-phase four-wire unified power quality conditioner (upqc) to deal with the problems of power quality under distortional and unbalanced load conditions. the proposed control approach is the combination of instantaneous power theory and synchronous reference frame (srf) theory which is optimized by using a self-tuning filter (stf) and without us...

There are two principal strategies for managing climate change risks: mitigation and adaptation. Until recently, mitigation and adaptation have been considered separately in both climate change science and policy. Mitigation has been treated as an issue for developed countries, which hold the greatest responsibility for climate change, while adaptation is seen as a priority for the South, where...
