PUBLISHED ON: Proceedings of the 22nd International System Dynamics Conference (ISDC) YEAR: 2004 ISBN: 0-9745329-0-8 AUTHOR/s: Armenia, Onori et al.- REFERENCE PEOPLE/ORGANISATION: Armenia, Onori USED TOOL: POWERSIM DESCRIPTION: The implementation of specific management control/decision support systems, based on System Dynamics models, allow first for a better learning of the environmental dynamics which influence the economic behavior of the firm, and second, for a deep understanding of the results of the decisional policies which the Chemist himself, together with his collaborating staff, may choose among a plethora of strategic choices. By ignoring that "structure influences behavior", all the actions, even the ones deemed most brilliant, may have a very different result if the very nature of the environment is not clear. A system dynamics approach has helped identifying those modeling and conflict resolution policies which may help in conducting a group model building session, towards the sharing of a common mental model and the collegiality of decisions which, in the long run, may bring economic success to the Chemist's business.

"Traditional policy analysis approaches are characterized by a focus on system modeling and choosing among policy alternatives. While successful in many cases, this approach has been increasingly criticized for being technocratic and ignoring the behavioral and political dimensions of most policy processes. In recent decades, increased awareness of the multi-actor, multiple perspective, and poly-centric character of many policy processes has led to the development of a variety of different perspectives on the styles and roles of policy analysis, and to new analytical tools and approaches - for example, argumentative approaches, participative policy analysis, and negotiation support. As a result, the field has become multi-faceted and somewhat fragmented. Public Policy Analysis: New Developments acknowledges the variety of approaches and provides a synthesis of the traditional and new approaches to policy analysis. It provides an overview and typology of different types of policy analytic activities, characterizing them according to differences in character and leading values, and linking them to a variety of theoretical notions on policymaking. Thereby, it provides assistance to both end users and analysts in choosing an appropriate approach given a specific policy situation. By broadening the traditional approach and methods to include the analysis of actors and actor networks related to the policy issue at hand, it deepens the state of the art in certain areas. While the main focus of the book is on the cognitive dimensions of policy analysis, it also links the policy analysis process to the policymaking process, showing how to identify and involve all relevant stakeholders in the process, and how to create favorable conditions for use of the results of policy analytic efforts by the policy actors."

PUBLISHED ON: Proceedings of the 22nd International System Dynamics Conference (ISDC) YEAR: 2011ISBN: 978-1-935056-08-9AUTHOR/s: Armenia, Stefano, Yannis Charalabidis, Diego Falsini, Fenareti Lampathaki, David Osimo and Katarzyna SzkutaREFERENCE PEOPLE/ORGANISATION: Crossroads ProjectLINKS: http://crossroad.epu.ntua.gr/ DESCRIPTION: The role of Government has evolved over the last thirty years and while its role in service provision has diminished, its regulation activity is growing. The world has become increasingly interconnected, complex, and fast-evolving and the effects of individual behavior and policy choices are not predictable. The paradox is that while the amount of data available to governments has increased exponentially, yet policymakers clearly struggle to make sense of it so that during the last years, the European Commission has decided to invest heavily in research on this issue. In this paper, the authors report about their experience in the CROSSROAD Project, whose main goal was to build a roadmap in order to provide strategic directions for future research in the domain of "ICT for Governance and Policy Modelling". The roadmap, recently approved by European Commission, intends to be the basis for developing a shared vision, inspire collaborative and interdisciplinary research between academia, business, civil society and government, and provide support and orientation to policy-modeling also after the project end. In this context, the paper analyzes the Model-based Governance issue as the part of the roadmap that suggests the development of advanced tools for an efficient and effective decision-making process.

REFERENCE PEOPLE/ORGANISATION: XJ-Technologies LINKS: http://www.xjtek.com/ DESCRIPTION: AnyLogic is the only tool that supports all the most common simulation methodologies in place today: System Dynamics, Process-centric (AKA Discrete Event), and Agent Based Modeling. The unique flexibility of the modeling language enables the user to capture the complexity and heterogeneity of business, economic and social systems to any desired level of detail. AnyLogic's graphical interface, tools, and library objects allow you to quickly model diverse areas such as manufacturing and logistics, business processes, human resources, consumer and patient behavior. The object-oriented model design paradigm supported by AnyLogic provides for modular, hierarchical, and incremental construction of large models.

Forio simulations improve public policy development and implementation by allowing you to: *Model sophisticated behaviors by importing data and formulas from Excel, AnyLogic, and other programs. *Have global access to your Sim via popular web browsers. *Control access with secure user privileges. *Implement updates centrally, ensuring users have the most up-to-date information (preventing old or obselete info from being reused). *Operate worry-free, with dependable security and design measures. Customized simulations apps are easily accessible via standard web browsers, allowing users to easily make adjustments, share and compare results. With Forio's public policy simulations, users can create interactive online tools to generate, manipulate and illustrate "what if" scenarios that are ideal for long-term policy models.With Forio's public policy simulations, users can create interactive online tools to generate, manipulate and illustrate "what if" scenarios that are ideal for long-term policy models.

Catastrophic events have raised numerous issues concerning how effectively the built environment accommodates the evacuation needs of individuals with disabilities. Individuals with disabilities represent a significant, yet often overlooked, portion of the population disproportionately affected in emergency situations. Incorporating disability considerations into emergency evacuation planning, preparation, and other activities is critical. The most widely applied method used to evaluate how effectively the built environment accommodates emergency evacuations is agent-based or microsimulation modeling. However, current evacuation models do not adequately address individuals with disabilities in their simulated populations. This manuscript describes the BUMMPEE model, an agent-based simulation capable of classifying the built environment according to environmental characteristics and simulating a heterogeneous population according to variation in individual criteria. The method allows for simulated behaviors which more aptly represent the diversity and prevalence of disabilities in the population and their interaction with the built environment. Comparison of the results of an evacuation simulated using the BUMMPEE model is comparable to a physical evacuation with a similar population and setting. The results of the comparison indicate that the BUMMPEE model is a reasonable approach for simulating evacuations representing the diversity and prevalence of disability in the population.
