Modelling the Role of Software in the Propagation of Failures Across National Critical Infrastructures
نویسنده
چکیده
Previous terrorist attacks, system failures and natural disasters have revealed the problems that many States face in preparing for national civil contingencies. The diversity of critical infrastructures and the interconnections between different systems makes it difficult for planners to ‘think of everything’. For example, the loss of power distribution networks can disrupt rail and road transportation systems. Knock-on effects can also be felt across telecommunications infrastructures as the uninterruptible power supplies (UPS’) that protect mobile phone base stations fail over time. Domestic water supplies are affected when pumping and treatment centres lose power.

Assessing the Performance of Corroding RC Bridge Decks: A Critical Review of Corrosion Propagation Models
Corrosion of steel reinforcement is one of the most prevalent causes of reinforced concrete (RC) structures deterioration in chloride-contaminated environments. As a result, evaluating the impact of any possible corrosion-induced damages to reinforced concrete bridges strongly affects management decisions: such as inspection, maintenance and repair actions. The corrosion propagation phase is a ...

In recent decades, population growth and progress of technology have shaped large and compact urban settlements. Existence of huge transportation systems and developed urban infrastructures are among the most important properties of modern cities. In spite of prompt transit and facilitated daily activities, development of transportation systems causes many problems, including traffic, air and n...
متن کاملCrack Tip Constraint for Anisotropic Sheet Metal Plate Subjected to Mode-I Fracture
On the ground of manufacturing, sheet metal parts play a key role as they cover about half of the production processes. Sheet metals are commonly obtained from rolling and forming processes which causes misalignment of micro structure resulting obvious anisotropic characteristics and micro cracks. Presence of micro cracks poses serious attention, when stresses at the tip reach to the critical v...

Technological advancement in the manufacturing system in current scenario is inevitable due to today’s customer-driven and volatile nature of the market. Implementation of agent technology in a manufacturing system increases flexibility which handles uncertainty generated due to advance technology. Therefore, in this paper, the critical drivers affecting implementation of agent technology are i...
متن کاملIdentification of sources of failures and their propagation in critical infrastructures from 12 years of public failure reports
Modern Communication and Information Technology Infrastructure (CITI) provides key links and services to many other critical infrastructures [1], such as telecommunication, electricity, water supply, oil and gas networks, transportation, financial services, etc. Over the years, integration of these infrastructures with CITI has become pervasive, extensive, and complex. As such, failure in CITI,...
