The volume provides a comprehensive, up-to-date account on recent developments concerning the incorporation of fuzzy capabilities in Petri Net models. The results of such studies originated the class of models that have been designated by Fuzzy Petri Nets. The recent papers specially elaborated for this volume range over several aspects of fuzziness in Petri nets. They form an interesting collection of original works that covers a great variety of relevant problems concerning the concept of Fuzzy Petri Net model. The articles approach several of the most outstanding issues in the framework of Fuzzy Petri nets, such as the representation of time, consistency checking, learning, design, computational efficiency, modelling flexibility, among others. From the material collected in the book one can extract the points of view of leading researchers concerning the basic and advanced concepts, advantages, potential applications and open problems, related to the field.

This edited book focuses on recent developments in Dynamic Network Modeling, including aspects of route guidance and traffic control as they relate to transportation systems and other complex infrastructure networks. Dynamic Network Modeling is generally understood to be the mathematical modeling of time-varying vehicular flows on networks in a fashion that is consistent with established traffic flow theory and travel demand theory. Dynamic Network Modeling as a field has grown over the last thirty years, with contributions from various scholars all over the field. The basic problem which many scholars in this area have focused on is related to the analysis and prediction of traffic flows satisfying notions of equilibrium when flows are changing over time. In addition, recent research has also focused on integrating dynamic equilibrium with traffic control and other mechanism designs such as congestion pricing and network design. Recently, advances in sensor deployment, availability of GPS-enabled vehicular data and social media data have rapidly contributed to better understanding and estimating the traffic network states and have contributed to new research problems which advance previous models in dynamic modeling. A recent National Science Foundation workshop on “Dynamic Route Guidance and Traffic Control” was organized in June 2010 at Rutgers University by Prof. Kaan Ozbay, Prof. Satish Ukkusuri , Prof. Hani Nassif, and Professor Pushkin Kachroo. This workshop brought together experts in this area from universities, industry and federal/state agencies to present recent findings in this area. Various topics were presented at the workshop including dynamic traffic assignment, traffic flow modeling, network control, complex systems, mobile sensor deployment, intelligent traffic systems and data collection issues. This book is motivated by the research presented at this workshop and the discussions that followed.

This book provides an early exploration of the new field of disaster bioethics: examining the ethical issues raised by disasters. Healthcare ethics issues are addressed in the first part of this book. Large-scale casualties lead to decisions about who to treat and who to leave behind, cultural challenges, and communication ethics. The second part focuses on disaster research ethics. With the growing awareness of the need for evidence to guide disaster preparedness and response, more research is being conducted in disasters. Any research involving humans raises ethical questions and requires appropriate regulation and oversight. The authors explore how disaster research can take account of survivors? vulnerability, informed consent, the sudden onset of disasters, and other ethical issues. Both parts examine ethical challenges where seeking to do good, harm can be done. Faced with overwhelming needs and scarce resources, no good solution may be apparent. But choosing the less wrong option can have a high price. In addition, what might seem right at home may not be seen to be right elsewhere. This book provides in-depth and practical reflection on these and other challenging ethical questions arising during disasters. Scholars and practitioners who gathered at the Brocher Foundation in Geneva, Switzerland in 2011 offer their reflections to promote further dialogue so that those devastated by disasters are respected by being treated in the most ethically soun d ways possible.
