This book offers a cross disciplinary treatment of the rapidly
growing field of integrated approaches in risk assessment in
mountainous areas. All major aspects related to hazard and risk
assessment, risk management, and governance are illustrated with a
wide range of case studies. The first part of the book focuses on
new techniques for assessing the natural hazards of different types
of mass movements. State-of-the-art techniques for morphological
characterization and monitoring of displacements are described.
Computational advances are covered to explain the process systems
and to quantify the hazards of fast and slow-moving landslides. In
the second part of the book methodologies are included for
assessing the impact of these natural hazards on the society in
terms of risks. In this part, methodologies for defining the
vulnerability of the elements at risk are shown and the use of
run-out models for risk assessment of the dangerous rapid mass
movements are evaluated. The third part of the book focuses on the
response of society towards the problems of hazard and risk. It
highlights the role of spatial planning, early warning systems and
evacuation plans for risk management. It establishes practical
thresholds for acceptable and tolerable risks and emphasizes the
importance of education and communication to society. Audience The
book is of interest to a wide range of experts from related
disciplines, practitioners and stakeholders to demonstrate the
importance of an integrated approach for all aspects of risks in
mountainous areas.
One of the most critical issues facing supply chain managers in
today's globalized and highly uncertain business environments is
how to deal proactively with disruptions that might affect the
complicated supply networks characterizing modern enterprises.
Supply Chain Disruptions: Theory and Practice of Managing Risk
presents a state-of the-art perspective on this particular issue.
Supply Chain Disruptions: Theory and Practice of Managing Risk
demonstrates that effective management of supply disruptions
necessitates both strategic and tactical measures - the former
involving optimal design of supply networks; the latter involving
inventory, finance and demand management. It shows that managers
ought to use all available levers at their disposal throughout the
supply network - like sourcing and pricing strategies, providing
financial subsidies, encouraging information sharing and incentive
alignment between supply chain partners - in order to tackle supply
disruptions. The editors combine up-to-date academic research with
the latest operational risk management practices used in industry
to demonstrate how theoreticians and practitioners can learn from
each other. As well as providing a wealth of knowledge for students
and professors who are interested in pursuing research or teaching
courses in the rapidly growing area of supply chain risk
management, Supply Chain Disruptions: Theory and Practice of
Managing Risk also acts as a ready reference for practitioners who
are interested in understanding the theoretical underpinnings of
effective supply disruption management techniques.
Risk Culture is a practical volume devoted to the qualitative
aspects of risk management, including those that should be firmly
embedded in the corporate culture. Through descriptions, examples
and case studies, the book analyzes weak and strong cultures and
proposes a series of structural and behavioral actions to
strengthen a company's culture.
This book is unique in identifying and presenting tools to
environmental decision-makers to help them improve the quality and
clarity of their work. These tools range from software to policy
approaches, and from environmental databases to focus groups. This
title is equally of value to environmental managers, and students
in environmental risk, policy, economics and law.
Managing Towards Supply Chain Maturity takes a view of the crucial
issues involved in supply chain management, namely risk,
information and social capital management. Over the last dozen or
so years, the outsourcing and offshoring processes have grown in
importance. It is now more and more the case that enterprises
concentrate on their key competences while transferring operations
or specific tasks to other countries. Modern supply chains are
becoming supply networks; hence there is a need for conscious and
concerted implementation of methods to manage risk, information and
social capital. These issues are very important for the efficiency
and competitiveness of supply chains and are discussed in detail.
The discussion includes the results of research and introduces the
concept of risk, information and social capital management that
will ensure supply chain excellence and maturity according to the
Poirier's model that has been taken as the point of reference for
this study. From a managerial point of view this study can play a
significant role in determining the best risk and information
management practices in the context of the outsourcing and
offshoring of business processes.
The International Section on Machine and System Safety was founded
in 1975 to deal with questions on occupational risks in this ?eld
at the inter- tional level. It is a member of the Special
Commission on Prevention of the International Social Security
Association (ISSA). The Special Commission is a body within ISSA
that focuses on work-related risks. It has 11 inter- tional
Sections as members. ISSA was founded in 1927 with its headquarters
in Geneva. It is working worldwide in over 150 countries with
nearly 370 member institutions from all ?elds of social security.
TheSection on Machine and System Safety, when it was founded, had
its focus on machine safety, particularly on the ma- facturing of
safe machinery, on assisting developing countries to be able to buy
safe used machinery, and on delivering clear operating
instructions. Our members and partners are: * institutions for
safety and health at work; * insurance companies dealing with
work-related risks; * research institutions; and * various
enterprises, e.g. manufacturers, importers and users of machines
and systems/installations. We thus bring together the experiences
of our members and partners. The role of the operators soon grew in
importance, and their capability for ha- ling machinery became an
important factor for the safety and success of enterprises. The
growing importance and complexity of handling different
man-machine-environment situations created new challenges and led
to - larging the Section's tasks to machine and system safety.
When is it morally acceptable to expose others to risk? Most moral
philosophers have had very little to say in answer to that
question, but here is a moral philosopher who puts it at the centre
of his investigations. Sven Ove Hansson shows why traditional moral
theories are ill suited to deal with risk and uncertainty, and
proposes new approaches that can do so much better. The book
contains many examples that connect moral philosophy to the
practical world of risk management in new ways. This is an
important book for moral philosophers as it opens up a new area for
ethical investigations. It is equally important for risk analysts
and policy makers who need input from moral philosophy in order to
deal with the difficult normative issues that arise in
decision-making under risk and uncertainty.
For a long time, conventional reliability analyses have been
oriented towards selecting the more reliable system and preoccupied
with maximising the reliability of engineering systems. On the
basis of counterexamples however, we demonstrate that selecting the
more reliable system does not necessarily mean selecting the system
with the smaller losses from failures! As a result, reliability
analyses should necessarily be risk-based, linked with the losses
from failures.
Accordingly, a theoretical framework and models are presented which
form the foundations of the reliability analysis and reliability
allocation linked with the losses from failures.
An underlying theme in the book is the basic principle for a
risk-based design: the larger the cost of failure associated with a
component, the larger its minimum necessary reliability level. Even
identical components should be designed to different reliability
levels if their failures are associated with different losses.
According to a classical definition, the risk of failure is a
product of the probability of failure and the cost given failure.
This risk measure however cannot describe the risk of losses
exceeding a maximum acceptable limit. Traditionally the losses from
failures have been 'accounted for' by the average production
availability (the ratio of the actual production capacity and the
maximum production capacity). As demonstrated in the book by using
a simple counterexample, two systems with the same production
availability can be characterised by very different losses from
failures.
As an alternative, a new aggregated risk measure based on the
cumulative distribution of the potential losses has been
introducedand the theoretical framework for risk analysis based on
the concept potential losses has also been developed. This new risk
measure incorporates the uncertainty associated with the exposure
to losses and the uncertainty in the consequences given the
exposure. For repairable systems with complex topology, the
distribution of the potential losses can be revealed by simulating
the behaviour of systems during their life-cycle. For this purpose,
fast discrete event-driven simulators are presented capable of
tracking the potential losses for systems with complex topology,
composed of a large number of components. The simulators are based
on new, very efficient algorithms for system reliability analysis
of systems comprising thousands of components.
An important theme in the book are the generic principles and
techniques for reducing technical risk. These have been classified
into three major categories: preventive (reducing the likelihood of
failure), protective (reducing the consequences from failure) and
dual (reducing both, the likelihood and the consequences from
failure). Many of these principles (for example: avoiding
clustering of events, deliberately introducing weak links, reducing
sensitivity, introducing changes with opposite sign, etc.) are
discussed in the reliability literature for the first time.
Significant space has been allocated to component reliability. In
the last chapter of the book, several applications are discussed of
a powerful equation which constitutes the core of a new theory of
locally initiated component failure by flaws whose number is a
random variable.
This book has been written with the intention to fill two big gaps
in the reliability and riskliterature: the risk-based reliability
analysis as a powerful alternative to the traditional reliability
analysis and the generic principles for reducing technical risk. I
hope that the principles, models and algorithms presented in the
book will help to fill these gaps and make the book useful to
reliability and risk-analysts, researchers, consultants, students
and practising engineers.

Epidemics know no borders and are often characterized by a high
level of uncertainty, causing major challenges in risk governance.
The author shows the emergence of global risk governance processes
and the key role that the World Health Organization (WHO) plays
within them.
Decision making in environmental projects is typically a complex
and confusing process characterized by trade-offs between
socio-political, environmental, and economic impacts. Comparative
Risk Assessment (CRA) is a methodology applied to facilitate
decision making when various activities compete for limited
resources. CRA has become an increasingly accepted research tool
and has helped to characterize environmental profiles and
priorities on the regional and national level. CRA may be
considered as part of the more general but as yet quite academic
field of multi-criteria decision analysis (MCDA). Considerable
research in the area of MCDA has made available methods for
applying scientific decision theoretical approaches to
multi-criteria problems, but its applications, especially in
environmental areas, are still limited. The papers show that the
use of comparative risk assessment can provide the scientific basis
for environmentally sound and cost-efficient policies, strategies,
and solutions to our environmental challenges.
The Art and Science of Making Up Your Mind presents basic
decision-making principles and tools to help the reader respond
efficiently and wisely to everyday dilemmas. Although most
decisions are made informally (whether intuitively without
deliberate thought, or based on careful reflection), over the
centuries people have tried to develop systematic, scientific and
structured ways in which to make decisions. Using qualitative
counterparts to quantitative models, Rex Brown takes the reader
through the basics, like 'what is a decision' and then considers a
wide variety of real-life decisions, explaining how the best
judgments can be made using logical principles. Combining multiple
evaluations of the same judgment ("hybrid judgment") and exploring
innovative analytical concepts (such as "ideal judgment"), this
book explores and analyzes the skills needed to master the basics
of non-mathematical decision making, and what should be done, using
real world illustrations of decision methods. The book is an ideal
companion for students of Thinking, Reasoning and Decision-Making,
and also for anyone wanting to understand how to make better
judgments in their everyday lives.
The concept of fuzziness, inspired by Zadeh (1965), brings us
fruitful results when it is applied to problems in decision making.
Recently, problems in fuzzy decision making are getting more
complex, and one of the most complex fac tors is dynamics in
systems. Dynamical approach to fuzzy decision making has been
proposed by Bellman and Zadeh's celebrated paper "Decision-making
in a fuzzy environment" (1970). The idea has developed into fuzzy
mathemati cal programming and has been applied in many fields
including management science, operations research, control theory,
engineering, systems analysis, computer science, mathematical
finance etc. Dynamic programming, advo cated in Bellmans book
"Dynamic programming" (1957), is one of the most powerful tools to
deal with dynamics in systems, and Bellman and Zadeh has proposed
the optimality principle in fuzzy decision making by (1970)
introducing fuzzy dynamic programming. Fuzzy dynamic programming
and fuzzy mathematical programming has been making remakable
progress after they were given life by Bellman and Zadeh's paper
(1970). In this volume, various kinds of dynamics, not only time
but also structure of systems, are considered. This volume contains
ten reviewed papers, which deal with dynamics in theory and
applications and whose topics are poten tially related to dynamics
and are expected to develope dynamical study in near future. first,
fuzzy dynamic programming is reviewed from a viewpoint of its
origin and consider its developement in theory and applications."
This edited book contains several state-of-the-art papers devoted
to econometrics of risk. Some papers provide theoretical analysis
of the corresponding mathematical, statistical, computational, and
economical models. Other papers describe applications of the novel
risk-related econometric techniques to real-life economic
situations. The book presents new methods developed just recently,
in particular, methods using non-Gaussian heavy-tailed
distributions, methods using non-Gaussian copulas to properly take
into account dependence between different quantities, methods
taking into account imprecise ("fuzzy") expert knowledge, and many
other innovative techniques. This versatile volume helps
practitioners to learn how to apply new techniques of econometrics
of risk, and researchers to further improve the existing models and
to come up with new ideas on how to best take into account economic
risks.
