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
Half‐life
The time required for a stock to move halfway towards its goal. Associated with goal‐seeking behavior. The half‐life is the converse of doubling time in positive feedback.
High‐leverage point (high‐leverage parameter)
Part of a system where small changes can have a very large impact on system behavior and is therefore effective for focusing system design, management attention and resources.
Homeostasis
The tendency of organisms to preserve their equilibrium conditions. Control through the operation of negative feedback loops—homeostasis is reached when the goal is attained and stable equilibrium achieved.
Impulse
Theoretically, a signal of zero duration but non‐zero finite height and area. Practically, in simulation models, a signal (flow) of specified area lasting for one solution interval and occurring at a specified time.
Information delay
A delay that represents the gradual adjustment of information, perceptions or beliefs, or a gradually delayed impact of some variable on a flow or auxiliary variable. Used to model non‐conserved variables.
Integration
See accumulation.
Integration error
Error generated in computer simulations due to the mathematical method used to approximately compute variable values.
Limits to growth
A resource constraint, an external or internal limiting response to growth. An initial growth begins to slow and eventually comes to a halt at the limit, and may even reverse itself and collapse.
Linear system
A system in which all relations between variables are mathematically linear. In such systems, the complete behavior can be found by superimposing different behavior modes without interacting with one another.
Link polarity
See causal link polarity.
Little's law
The relationship among the size of a stock, the net flow into or out of the stock, and the average time material stays in the stock under conditions of perfect mixing and when the system is in equilibrium. At equilibrium, the size of the stock is the product of the net flow and the delay.
Look‐up function
See table function.
