Evaluating system dynamics models of risky projects using decision trees: alternative energy projects as an illustrative example

Burcu Tan, Edward G. Anderson, James S. Dyer, Geoffrey G. Parker

System Dynamics Review > 26 > 1 > 1 - 17

Many important risky projects are characterized by stochastic processes embedded in nonlinear, feedback structures with delays. System dynamics models may be used to estimate the cash flow resulting from these projects for any given predetermined sequence of decisions. However, using system dynamics models to evaluate these cash flows when management has the flexibility to change its decisions in...

Assessing individuals' understanding of nonlinear causal structures in complex systems

Richard Plate

System Dynamics Review > 26 > 1 > 19 - 33

Educators have provided anecdotal evidence that systems‐oriented instruction improves students' ability to comprehend complex systems, but little research has been done to test this hypothesis. This article reviews past attempts to assess systems‐oriented instruction and suggests the need for an assessment tool that can be implemented broadly but still provides a nuanced view of individuals' understanding...

Change resistance as the crux of the environmental sustainability problem

Jack Harich

System Dynamics Review > 26 > 1 > 35 - 72

Why, despite over 30 years of prodigious effort, has the human system failed to solve the environmental sustainability problem? Decomposing the problem into two sequential subproblems, (1) how to overcome change resistance and (2) how to achieve proper coupling, opens up a fresh line of attack. A simulation model shows that in problems of this type the social forces favoring resistance will adapt...

Improving model understanding using statistical screening

Timothy R. B. Taylor, David N. Ford, Andrew Ford

System Dynamics Review > 26 > 1 > 73 - 87

System dynamics models are often constructed to improve system performance by identifying and modifying feedback mechanisms that drive system behavior. Once identified, these feedback mechanisms can be used to design and test policies for system performance improvement. A preliminary step in developing policies is the identification of high‐leverage parameters and structures, the influential model...

Policy analysis for online game addiction problems

Bong‐Won Park, Jae‐Hyeon Ahn

System Dynamics Review > 26 > 2 > 117 - 138

With the worldwide popularity of online games, game addiction is a serious social issue. To address online game addiction problems and pursue the steady growth of the online gaming industry, we propose and evaluate two policies using a system dynamics approach: a self‐regulation policy and a tax and rebate policy. Through our analysis, we demonstrate that the tax and rebate policy can be a very effective...

Economic transition management in a commodity market: the case of the Iranian cement industry

Navid Ghaffarzadegan, Amir T. Tajrishi

System Dynamics Review > 26 > 2 > 139 - 161

Economic transition management is an important issue in countries that have not completely adjusted to the market economy style, as well in countries that temporarily implement price controls. The common concern is to manage the transition in a way that lessens the socio‐economic side effects of the process. This paper presents policy recommendations for the Iranian cement industry, which will undergo...

Generic structure to simulate acceptance dynamics

Silvia Ulli‐Beer, Fritz Gassmann, Mathias Bosshardt, Alexander Wokaun

System Dynamics Review > 26 > 2 > 89 - 116

Social behaviour patterns and social equilibrium states are often guided by stable values such as social norms. However, changing environmental conditions (e.g. climate warming, resource scarcity) may require behavioural change and the acceptance of new technologies. Antecedents of aggregate behavioural change are value changes that predetermine when new behaviour patterns emerge and a new social...

Ulysse: a qualitative tool for eliciting mental models of complex systems

Gilles Desthieux, Florent Joerin, Marcel Lebreton

System Dynamics Review > 26 > 2 > 163 - 192

Stakeholders involved in the definition of managerial problems perceive and internalize the complexity of these problems as mental models. These models are not always made explicit, which can lead to misunderstandings and conflicts. This article presents Ulysse, a tool that enables stakeholders to progressively elicit their mental models as causal loop models. Ulysse uses web technologies that store...

Optimizing highway maintenance operations: dynamic considerations

Saeideh Fallah‐Fini, Hazhir Rahmandad, Konstantinos Triantis, Jesus M. de la Garza

System Dynamics Review > 26 > 3 > 216 - 238

Effective highway maintenance depends on several activities, including the understanding of current and the prediction of future pavement conditions and deciding how to best allocate limited resources for maintenance operations. In this paper, a dynamic micro‐level simulation model of highway deterioration and renewal processes is presented. This model is calibrated with data from eight road sections...

Understanding short‐ and long‐term implications of “myopic” fleet maintenance policies: a system dynamics application to a city bus company

Enzo Bivona, Giovan Battista Montemaggiore

System Dynamics Review > 26 > 3 > 195 - 215

Financial losses recorded in city bus companies often force managers to implement restructuring strategies aimed at improving business results. However, such decisions may not produce the expected consequences for a number of reasons. Both the internal and external environment in which such companies operate can make the design and implementation of long‐term sustainable policies quite difficult....

Impact assessment in the automotive industry: mandatory market introduction of alternative powertrain technologies

Grit Walther, Jörg Wansart, Karsten Kieckhäfer, Eckehard Schnieder, more

System Dynamics Review > 26 > 3 > 239 - 261

Increasing numbers of regulatory measures are being introduced worldwide to reduce emissions from the transportation sector. In California, whose low emission vehicle regulations have a leading position worldwide, automobile manufacturers must reduce greenhouse gas emissions of their vehicle fleet (GHG regulations) and sell increasing shares of zero emission vehicles (ZEV regulations). Manufacturers...

A system dynamics approach to land use transport interaction modelling: the strategic model MARS and its application

Paul Pfaffenbichler, Günter Emberger, Simon Shepherd

System Dynamics Review > 26 > 3 > 262 - 282

Land use transport interaction models have been developed in various forms dating back to the early 1960s. They have moved from spatial interaction models or statistical models through econometric models to micro‐simulation, cell‐based automata and agent‐based models. There has been a move towards more detail in representing space and individual behaviour. This paper presents an alternative approach...

The ASTRA model for strategic assessment of transport policies

Davide Fiorello, Francesca Fermi, Dorota Bielanska

System Dynamics Review > 26 > 3 > 283 - 290

ASTRA is a system dynamics model for the strategic assessment of policy scenarios at the European level. Over recent years, ASTRA has been extensively used in many European research projects, sometimes in linkage with other strategic tools, to provide simulations of scenarios concerning energy scarcity, high oil prices, technological investments in the transport sector and application of measures...

Effects of domain experience in the stock–flow failure

Angela Brunstein, Cleotilde Gonzalez, Steven Kanter

System Dynamics Review > 26 > 4 > 347 - 354

Misperceptions of stock and flow relationships are pervasive and an important problem to solve in system dynamics. Prior studies have shown that individuals perform poorly on accumulation problems, even when considering relatively simple systems, an effect termed the Stock–Flow (SF) failure. This study examines the effects of domain experience in overcoming the SF failure. We compared performance...

Does formal system dynamics training improve people's understanding of accumulation?

John D. Sterman

System Dynamics Review > 26 > 4 > 316 - 334

Research shows widespread misunderstanding of stocks and flows, even among highly educated adults. People fail to grasp that any stock rises (falls) when the inflow exceeds (is less than) the outflow. Rather, people often use the correlation heuristic, concluding that a system's output is positively correlated with its inputs. Although many argue that system dynamics training will help, evidence is...

Using a group decision support system to add value to group model building

Fran Ackermann, David F. Andersen, Colin Eden, George P. Richardson

System Dynamics Review > 26 > 4 > 335 - 346

This note intends to contribute to the practice of group model building by presenting group model‐building scripts that can (1) create a preliminary problem boundary using less than one hour of group time, (2) convene discussions with the group that explicitly link dynamic structure with system behaviour, and (3) allow participants to “zoom” between a micro and a macro view of system structure. These...

Modeling the rework cycle: capturing multiple defects per task

Hazhir Rahmandad, Kun Hu

System Dynamics Review > 26 > 4 > 291 - 315

The rework cycle is at the heart of modeling projects, one of the major research and application areas in system dynamics. The current formulations for the rework cycle assume each task is either defective or not. Yet in many projects multiple defects can occur in one task. In this study we introduce a new rework cycle formulation that accounts for multiple defects per task and flexibly captures the...

Modeling as persuasion: the impact of group model building on attitudes and behavior

Etiënne A. J. A. Rouwette, Hubert Korzilius, Jac A. M. Vennix, Eric Jacobs

System Dynamics Review > 27 > 1 > 1 - 21

Client involvement in modeling is expected to change mental models and thereby foster implementation of conclusions. Leading authors have pointed out that a lack of knowledge on the crucial elements of modeling interventions hinders accumulation of research results. There is no clear evidence for the effectiveness of group model building, and a conceptual model linking elements of the modeling process...

Pharmaceutical market dynamics and strategic planning: a system dynamics perspective

Mark Paich, Corey Peck, Jason Valant

System Dynamics Review > 27 > 1 > 47 - 63

Competitive pressures are forcing pharmaceutical companies to develop even more effective product‐based strategic plans, which have traditionally been derived from unarticulated mental models about the individual diseases and the role of various decision‐makers within them. The industry is blessed with a wealth of patient‐ and physician‐level data, but often this information is not leveraged to its...
