System dynamics for business strategy: a phased approach

Abstract

Detailed, calibrated system dynamics models offer an effective tool for supporting business strategy. They correspond to the business lines and planning approaches of the organization, serve as an important check on the adequacy of the model as a representation of the system, provide accurate assessments of the cost–benefit tradeoffs of alternative strategies, and allow results to be more easily sold to others. However, detailed models also have disadvantages: they are complex, can be more difficult to understand, and run the risk of becoming “black boxes”. This paper discusses a four‐phased approach to consulting that, building from other system dynamics modeling styles (“systems thinking” and small, insight‐based models), offers an effective means of developing detailed models while simultaneously educating the client. The approach is illustrated with case examples from the credit card and aircraft industries. Copyright © 1999 John Wiley & Sons, Ltd.

Assessing the Effects of Climate Change Regulations on the Business Community: A System Dynamic Approach

“…Yim et al () emphasize that meaningful information can be elicited from either managers/experts' mental models or relative documents. The analysis of documents and interviews of managers or other stakeholders should be based on the model development team's strategy to exploit essential information (Lyneis, ). Generally, this step can be characterized as a consultation process, wherein lengthy and wide ranging discussions on issues related to the system's behavior take place between the modeling team and all interested parties.…”

The great challenge for system dynamics on the path forward: implementation and real impact

“…Here are some initial candidates for the list: Use small, understandable models .When is simplicity a good strategy for implementation (Ghaffarzadegan et al, )? Use realistic models—even if they are big .When is realism more important than simplicity (Lyneis, )? Use causal diagrams to communicate .For what type of audiences are causal diagrams helpful (Risch et al, )? Use time graphs to communicate .In what situations are plotted time series a useful tool (Graham, )?…”

An Energy-Economy-Environment Model for Simulating the Impacts of Socioeconomic Development on Energy and Environment

“…It promotes a more complicated, quantitative simulation and is able to achieve more robust and reliable outcomes [3]. Since the 1960s, several studies have used the system dynamic method to address or simulate scenarios in many different applications, such as in socioeconomic dynamics [4, 5], business systems [6], corporate planning and policy design [7], urban dynamics [8, 9], analysis of urban problems and responses to policy changes [10], agricultural systems [11], agricultural policy analysis [12], ecological systems [13], predicting flood patterns caused by snowmelt [14], water resources management [15], simulation of recharge and flow mechanisms in a fractured bedrock aquifer [16], simulating the process of accumulated metals treatment in constructed wetlands [17], implementing health care policies and programs [18], analyzing the impact of strategies for addressing epidemics, [19], environmental systems [20, 21], prediction of solid waste generation [22], analysis of collection capacity and electricity generation from solid waste [23], and even as a decision support tool to solve the coastal zone management problem [24]. …”
