In this game, we focus on the concept of simulation supported tabletop exercise and its application to risk management for bio-terrorism by smallpox. For the purpose we have developed the simulation model of the infection process by smallpox on a virtual city. The simulation supported tabletop exercise has designed on our simulation model for risk management by evaluating several types of policy scenarios against bio-terrorism by smallpox. The simulation supported tabletop exercise was executed by some professionals against bio-terrorism at Global Security Center, Keio University. We clarify the model structure of the simulation against bio-terrorism and its countermeasure policies. We also show the result executed at Global Security Center.Each player in this game becomes the decision-maker of policies in the virtual city against smallpox. Each player has to select one policy from each category and there are several categories. Players are required to consider the combination of policies. After deciding policies, player's policies are represented in the simulation model and player will get simulation results, and player's will know the effect of player's policies in a town.Many people do not matter the concept of this game, risk management –anti bio- terrorism. But people in the government, in the public health service, in the hospital and so on, do matter this concept. It is obviously impossible to test policies against bio-terrorism by smallpox in the real world but it is possible to test them in the virtual simulation model. From playing our game, we hope that our game will help people who do matter the game concept to review or reconsider some policies against –anti bio- terrorism in the real world.

AbstractIn this paper we discuss the structural foundations of micro‐economic exchange. To treat various features of the exchange in a general form, we formulate an algebraic system to serve as an abstraction of a bookkeeping system. First, we introduce the concept of an algebraic system to describe the micro‐economic activities of economic units. Next, we formulate an axiomatic system to capture the essence of economic transactions. Finally, we explicate the bookkeeping system in terms of this axiomatic system and make clear various notions concerning the micro‐economic activities of economic units. In this paper we consider only basic properties of this algebraic system; these become the mathematical foundation for a theory of an economic system.

The series of international workshops on Agent-Based Approaches in Economic and Social Complex Systems (AESCS) is part of the worldwide activities on computational social and organizational sciences. The second workshop, AESCS '02, focusing on progress of agent-based simulation was held in Tokyo in August 2002. AESCS '02 explored the frontiers of the field. The importance of cumulative progress was emphasized in discussions of common tasks, standard computational models, replication and validation issues, and evaluation and verification criteria. Promoting multidisciplinary work in computational economics, organizational science, social dynamics, and complex systems, AESCS '02 brought together researchers from diverse fields. This book contains the invited papers by Robert Axtell, Shu-Heng Chen, and Takao Terano, along with selected papers collected in three major sections: Economic Systems, Marketing and Management, and Social Systems and Methodology

The primary purpose of this handbook is to clearly describe the current state of theories of systems sciences and to support their use and practice. There are many ways in which systems sciences can be described. This handbook takes a multifaceted view of systems sciences and describes them in terms of a relatively large number of dimensions, from natural and engineering science to social science and systems management perspectives. It is not the authors' intent, however, to produce a catalog of systems science concepts, methodologies, tools, or products. Instead, the focus is on the structural network of a variety of topics. Special emphasis is given to a cyclic–interrelated view; for example, when a theory of systems sciences is described, there is also discussion of how and why the theory is relevant to modeling or practice in reality. Such an interrelationship between theory and practice is also illustrated when an applied research field in systems sciences is explained. The chapters in the handbook present definitive discussions of systems sciences from a wide array of perspectives. The needs of practitioners in industry and government as well as students aspiring to careers in systems sciences provide the motivation for the majority of the chapters. The handbook begins with a comprehensive introduction to the coverage that follows. It provides not only an introduction to systems sciences but also a brief overview and integration of the succeeding chapters in terms of a knowledge map. The introduction is intended to be used as a field guide that indicates why, when, and how to use the materials or topics contained in the handbook.

AbstractThe anti‐vaccination movement is dangerous because of its influence on vaccine hesitancy. Nowadays, social media platforms become significant sources of anti‐vaccination information; therefore, combating their proliferation needs to be addressed by the relevant authorities. Previous studies suggested two policies to mitigate the negative influence of anti‐vaccination information online: attaching caution banners from healthcare authorities and engaging in censorship of anti‐vaccine supporting information providers. However, these recommendations were obtained without considering how the users form their sentiments. In this paper, we explore the influence of the existing network of vaccination‐related Facebook pages on an individual user's vaccination sentiment using agent‐based modelling (ABM). We use the ABM implementation of the Zaller model to convert the user's information consumption to their vaccination sentiment. Our simulation results show that the application of the two policies leads to improved sentiment on vaccination, reinforcing existing suggestions obtained by different methods.

The chapters of this book are the selected papers from those presented at the Third International Workshop on Agent-Based Approaches in Economic and Social Complex Systems held in Tokyo, Japan in 2005. Articles cover methodological issues, computational model/software, combination with gaming simulation, and real-world applications to economic, management/organizational and social issues.

Agent-based modeling/simulation is an emerging field that uses bottom-up and experimental analysis in the social sciences. Selected research from that presented at the Third International Workshop on Agent-Based Approaches in Economic and Social Complex Systems 2004, held in May 2004 in Kyoto, Japan, is included in this book. The aim of the workshop was to employ the bottom-up approach to social and economic problems by modeling, simulation, and analysis using a software agent. This research area is an emerging interdisciplinary field among the social sciences and computer science, attracting broad attention because it introduces a simulation-based experimental approach to problems that are becoming increasingly complex in an era of globalization and innovation in information technology. The state-of-the-art research and findings presented in this book will be indispensable tools for anyone involved in this rapidly growing discipline.

Agent-Based modeling/simulation is an emergent approach to the analysis of social and economic systems. It provides a bottom-up experimental method to be applied to social sciences such as economics, management, sociology, and politics as well as some engineering fields dealing with social activities. This book includes selected papers presented at the Fifth International Workshop on Agent-Based Approaches in Economic and Social Complex Systems held in Tokyo in 2007. It contains two invited papers given as the plenary and invited talks in the workshop and 21 papers presented in the six regular sessions: Organization and Management; Fundamentals of Agent-Based and Evolutionary Approaches; Production, Services and Urban Systems; Agent-Based Approaches to Social Systems; and Market and Economics I and II. The research presented here shows the state of the art in this rapidly growing field.

AbstractThis paper investigates the case of H5N1 bird flu in Southeast Asia, and develops a basic model of simulation using agent‐based modelling to study the dynamic interaction between human activities in Bandung City, West Java province, Indonesia. It evaluates the effectiveness of several policies for Bandung City based on the infection process model for pandemic, depending on social and culture simulation using Spot Oriented Agent Role Simulator or SOARS. The results of these simulations suggest that the government should take action not only from a medical perspective, but also from the perspective of social interactions and their influences on the spread of H5N1 in Bandung City.
