Linking feedback loops and system behavior is part of the foundation of system dynamics, yet the lack of formal tools has so far prevented a systematic application of the concept, except for very simple systems. Having such tools at their disposal would be a great help to analysts in understanding large, complicated simulation models. The paper applies(More)
Keywords: System dynamics Linear model analysis Eigenvalue analysis Leverage points a b s t r a c t Formal tools to link system dynamics model's structure to the system modes of behavior have recently become available. In this paper, we aim to expand the use of these tools to perform the model's policy analysis in a more structured and formal way than the(More)
We provide a review of different approaches to linking model structure to observed behavior with a particular view towards using models for theory building. We identify four such approaches, namely the " classical " approach, the " pathway participation " approach, the " eigenvalue elasticity " approach, and the " eigenvector " approach, respectively. We(More)
The purpose of the System Dynamics method is to study the relationship between structure and behavior in non-linear, dynamic systems. In such systems, the significance of various structural components to the behavior pattern exhibited, changes as the behavior unfolds. Changes in structural significance, in turn modifies that behavior pattern, which, in(More)
Previous work related to eigenvalue analysis in the system dynamics field has primarily focused on linking the model structure to the modes of behavior-i.e. the eigenvalues. While the system eigenvalues define the characteristics of the system's behavior modes (e.g., exponential growth, expanding oscillations), these behavior modes are not equally(More)
