Wenmei Gai、Yan Du、Yunfeng Deng《Decision-making Analysis and Optimization Modeling of Emergency Warnings for Major Accidents(精)》讲述了 highlights cutting-edge research into emergency early warning managementand decision-making for severe accidents. Using toxic gas leakages as examples, it putsforward new design methods for emergency early warning systems, as well as a sys-tematic description of emergency early warning information communication mecha-nisms and characteristics of regional evacuation, based on a wide range of theories,including safety engineering, information engineering, communication, behaviorologyand others. The book applies a range of methods, such as case analysis, question-naire interviews, and multi-objective optimization modeling. Drawing on this basis,it subsequently proposes a multi-objective optimization modeling and algorithmfor emergency path selection, together with an evacuation risk assessment method.Divided into six chapters, the book addresses the design of early warning systems,communication and dissemination mechanisms of early warning information, charac-teristics of regional evacuation, multi-objective optimization of emergency paths, andevacuation risk assessment. The book offers an essential reference guide for engineeringtechnicians and researchers in a wide range of fields, including emergency manage-ment, safety science and engineering, disaster relief engineering, and transportationoptimization, as well as graduate students in related majors at colleges and universities.
