摘要:

AbstractThis article describes the conceptual development of FOSSIL2, an integrated model of U.S. energy supply and demand, which is used to prepare projections for energy policy analysis in the U.S. Department of Energy's Office of Policy, Planning, and Analysis.

摘要:

AbstractValidation strategies for models of theories have received scant attention in the system dynamics literature. Yet if system dynamics is to be an effective tool for, evaluating the dynamic consistency of theoretical systems, such strategies will need to be developed. This article illustrates how such validation might take place by analyzing an already published model of Thomas S. Kuhn's theory of scientific revolutions. The results indicate that the model, while capturing many important aspects of Kuhnian science, distorts certain fundamental features of the theory, in particular the process of paradigm change. The article concludes by discussing some of the problems associated with incorporating truly Kuhnian paradigm change into any system dynamics model.

摘要:

AbstractThis article explores some requirements for applying qualitative simulation algorithms to system dynamics models. The field of qualitative simulation lacks a specific procedure for modeling systems (subjects of its models are generally physical systems). Bringing together qualitative simulation techniques and system dynamics modeling techniques could benefit both fields. The structural correctness of system dynamics models is defined using constraint theory. An attempt is made to alleviate some problems of qualitative simulation algorithms by drawing upon system dynamics modeling methods and by establishing the structure for the propagation of constraints in these models.
