While statistical models can provide insight into risks, the field is experiencing a sea change brought on by new advances in technology and data collection, including Big Data and the Internet of Things (IoT), said Dalal during his luncheon presentation. IoT describes the growing network of physical objects or "things" embedded with electronics, software, sensors and connectivity, enabling these objects to exchange data with their manufacturers, their operators and other connected devices.
With the increased ability to collect data through IoT and analyze this data in real time, the field of risk analysis is entering an exciting new phase based on real-time probabilistic risk analysis. This emerging paradigm can enable humans to better manage risks associated with complex systems, including space shuttles launching into orbit, illicit nuclear materials crossing national boundaries and the side effects of chemicals and even medical drugs, explained Dalal, who is an expert in the field of risk analysis and was appointed by the National Academy of Sciences to a panel commissioned to study the Challenger disaster. The panel's research demonstrated the ability of statistical science to predict risks to space shuttles and convinced the National Air and Space Administration (NASA) to establish a probabilistic risk assessment group...
JSM 2015 is being held August 8-13 at the Washington State Convention Center in Seattle. More than 6,000 statisticians—representing academia, business and industry, as well as national, state and local governments—from numerous countries are attending North America's largest statistical science gathering.
