摘要:

AbstractThis paper describes a framework for policy analysis and design in soft, complex systems based on the transfer to such systems of control modules developed for harder (more easily quantified), simpler systems. The framework is demonstrated by outlining the development of a dynamic allocation algorithm within a system dynamics model of an engineering system and describing its application in a much larger scale management system. The potential use of this algorithm is demonstrated in two other systems, and a generalized form is presented that highlights its isomorphic qualities. It is suggested that this framework, which treats the physical and control structure of a system as a unified whole, can provide a useful contribution to policy analysis.

摘要:

AbstractAccelerating the rate of economic growth in developing countries has been an important aim of almost all development policies implemented over the past three decades. Experience has shown that such growth is often not sustainable and is likely to be interrupted by violent political changes. This paper attempts to identify the organizational factors that limit economic growth and create conditions conducive to the outbreak of political violence. A system dynamics model of the sociopolitical organization of a developing country is presented, and the model's behavior is studied using computer simulation.

摘要:

AbstractThis paper presents a system dynamics model of the fledgling market for automated storage and retrieval AS/RS systems based on a case study of a leading firm in the industry. The model examines how marketing effort, capacity expansion, and industry reputation interact to produce growth cycles of eight to nine years' duration in demand and capacity for AS/RS systems. A series of partial model simulations is used to explain how the growth cycles are generated by the feedback structure and behavioral assumptions of the model. A policy experiment is presented to show how a mature firm in the industry can influence the growth cycles to improve its financial performance. Finally, the feedback structure governing market diffusion and capacity expansion is generalized to other high‐technology products and market

摘要:

AbstractIn this section theSystem Dynamics Reviewpresents problems having the potential to stimulate system dynamics research. Articles may address real‐world dynamic problems that could be approached fruitfully from the system dynamics perspective, or methodological problems affecting the field. A paper submitted to theResearch Problemssection should concisely motivate and define a problem and start a process of conceptualization or formulation that can open the way for further studie

摘要:

AbstractFounded in the mid‐1950s, the field of system dynamics has intellectual roots reaching much further into the past. The Archives section of the Review seeks to publish material from that past which can contribute to current theory and practice. The section welcomes previously unpublished but deserving system dynamics work, classics from past system dynamics literature that should receive renewed attention, and previously published articles from other disciplines of particular significance to current system dynamicists. Contributions emphasizing the philosophy and theory of model building, validation, implementation, education, and generic structures are particularly encouraged. Submissions may range in length from notes to main articles but may be edited. Send suggested material, together with a brief introduction placing it in historical and current contexts, to John D. Sterman, System Dynamics Group, M.I.T. E40‐294, Cambridge, MA 02139, U.

摘要:

AbstractThis section of theSystem Dynamics Reviewis an eclectic source of information on items of interest to the system dynamics community. Conferences, articles, books, dissertations, speeches, software and hardware products, and teaching materials will be mentioned in this space. The purpose of the section is to provide summaries to help the system dynamics community keep abreast of recent progress related to the field and to anticipate important future events. Submissions covering a wide range of areas and information of possible interest to system dynamicists are encouraged, and should be sent to R.
