Feedback loops — a basic concept of system dynamics Dependencies, such as advertising and brand perception, are often represented as loops called feedback loops. For instance, the more money you invest in marketing, the bigger revenues you have, and so, the more money you can spend on marke...
systems over time. It deals with internal feedback loops and time delays that affect the behaviour of the entire system. What makes using system dynamics different from other approaches to studying complex systems is the use of feedback loops and 系统动力学是方法到随着时间的过去了解复杂系统行为...
Learning StylesClassroom Assessment TechniquesThis paper examines the effectiveness of different delivery methods for teaching System Dynamics to undergraduate engineering students. The paper presents the findings from a survey of the learning styles of the student population and compares that to the curr...

The system dynamics approach is an object-oriented simulation method based on feedback loops, flow diagrams, and flow and state variables, which can be used in the development of a water system's operational policies and water-resource management. In reservoir operation simulations, there are itera...
A system dynamics structure to characterize the link between technology and critical management decisions in the drug discovery process (DDP) is needed. The DDP includes many interacting feedback loops that impact decisions executed in early stages and that influence performance in later development stag...
System dynamics enhance our understanding of the dynamic complexities within a value chain through the study of dynamic causes and effects using the feedback loops that control a system behaviour over time (Sterman, 2000; Maani and Cavana, 2007). It enables the quantitative analysis of economic,...
System dynamics centres on the idea that problems exist due to the interactions, feedback loops and material and information delays among component parts within a system. System dynamics therefore focuses on the relationships between the parts rather than focusing on separate parts in isolation [15]...
More broadly, while system dynamics models are often recognised for their ability to capture of feedback loops, nonlinear dynamics and system leverage points (Nicholson et al., 2020; Turner et al., 2016), numerous limitations remain relative to more traditional process-based trade-off models (Kan...
Consideration of the combined effects of system dynamics can improve management decisions and reduce the possibility of adverse side effects and unintended consequences from policy decisions (Sterman, 2000; Simonovic, 2009). Identifying and capturing feedback loops within water resource systems can ...
