Glosario de Dinámica de Sistemas
Este es el Glosario de Dinámica del Sistema compilado por David N. Ford y aceptado por Yaman Barlas. Fue publicado el 7 de noviembre de 2019 aquí: https://doi.org/10.1002/sdr.1641.
Introducción
Como un diccionario de enfoque limitado, este glosario define términos de uso común que son centrales para la Dinámica de Sistemas tradicional y algunos términos más generales que tienen significados especiales o importancia particular dentro de la dinámica del sistema. No se incluyen los términos generales que no tienen significados especiales en la Dinámica de Sistemas, los términos específicos de la aplicación y los términos específicos del software. Se remite al lector a la literatura relevante para esas definiciones, así como a descripciones detalladas, explicaciones y ejemplos de los términos incluidos aquí.

Concept | Description |
|---|---|
Rate | See flow. |
Reference mode | A behavior‐over‐time graph that depicts how one or more system variables change over time, often used in problem articulation to describe the dynamic hypothesis, and in model validation to test a model's ability to reproduce realistic behavior patterns. |
Reinforcing feedback loop | A feedback loop in which the sum effect of the causal links tends to strengthen (reinforce) the movement of variable values in a given direction due to positive feedback. |
Sensitivity analysis | Analysis used to determine how responsive model outputs are to changes in specific parameters, or policies or structures. Behavior that changes drastically suggests a critically important factor or high sensitivity. Conversely, if a large change in a parameter value or a structure results in small changes in behavior, that factor is not likely to be central to the dynamics in question; that is, the behavior shows low sensitivity. |
Simulation | The generation of the behavior of a system with a formal computer model. |
Sink | See cloud. |
Smoothing | Filtering out short‐term noise‐like fluctuations in a time series to detect or reveal underlying, significant patterns. |
Solution interval (computation interval, delta time (dt), time step) | The interval of time between successive computer calculations used to simulate behavior in a formal model. |
Source | See cloud. |
Stability (stable behavior) | Behavior in which the system moves toward equilibrium conditions after being disturbed or remains within specified limits. In an unstable system or region a disturbance is amplified, leading to increased growth, collapse or oscillation away from equilibrium. |
Stable equilibrium | A system structure and set of parameter values in which, if the system is moved away from the equilibrium conditions, the system tends to return to those conditions. See also unstable equilibrium. |
Stasis | See equilibrium behavior. |
