## Probabilistic risk analysis: foundations and methods

Risk is defined as the probability of harmful consequences, or expected losses deaths, injuries, property, livelihoods, economic activity disrupted or environment damaged resulting from interactions between natural or human-induced hazards and vulnerable conditions UN-ISDR, , EC, Risk can presented conceptually with the following basic equation indicated in Figure 1. Figure 1: Schematic representation of risk as the multiplication of hazard, vulnerability and quantification of the exposed elements-at-risk. The various aspects of hazards, vulnerability and elements-at-risk and their interactions are also indicated. This framework focuses on the analysis of physical losses, using physical vulnerability data. Risk assessment is a process to determine the probability of losses by analyzing potential hazards and evaluating existing conditions of vulnerability that could pose a threat or harm to property, people, livelihoods and the environment on which they depend UN-ISDR, ISO defines risk assessment as a process made up of three processes: risk identification, risk analysis, and risk evaluation.

Collapse risk analysis is of great significance for ensuring construction safety in foundation pits. This study proposes a comprehensive methodology for dynamic risk analysis of foundation pit collapse during construction based on a fuzzy Bayesian network FBN and a fuzzy analytical hierarchy process FAHP. Firstly, the potential risk factors contributing to foundation pit collapse are identified based on the results of statistical analysis of foundation pit collapse cases, expert inquiry, and fault tree analysis. Then, a FAHP and improved expert elicitation considering a confidence index are adopted to elicit the probability parameters of the BN. On this basis, quantitative risk reasoning and sensitivity analysis of foundation pit collapse are achieved by means of fuzzy Bayesian inference. Finally, an actual deep foundation pit in a metro station was used to illustrate a specific application of this approach, and the results were in accordance with the field observations and numerical simulation results.

EDU И далее текст сообщения: ГРОМАДНЫЙ ПРОГРЕСС. ЦИФРОВАЯ КРЕПОСТЬ ПОЧТИ ГОТОВА. ОНА ОТБРОСИТ АНБ НАЗАД НА ДЕСЯТИЛЕТИЯ. Сьюзан как во сне читала и перечитывала эти строки. Затем дрожащими руками открыла следующее сообщение. ТО: NDAKOTAARA.

Новость не обрадовала коммандера. Выслушав подробности, он долго молчал. Дэвид, - сказал наконец Стратмор мрачным голосом, - обнаружение этого кольца - вопрос национальной безопасности. Я возлагаю эту задачу на. Не подведите. И положил трубку. Дэвид, задержавшись в будке, тяжко вздохнул.

Она хорошо понимала, что в отчаянной ситуации требуются отчаянные меры, в том числе и от АНБ. - Мы не можем его устранить, если ты это имела в виду. Именно это она и хотела узнать.
