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
Controlling feedback loop
See balancing feedback loop.
Conveyor
A type of stock that represents a space into which material flows and stays for a fixed period of time, then exits. Its parameter determines transit time—how long material stays in the conveyor. Material that flows in at a given time is not mixed with material that flowed in earlier—a quantity that enters at t will flow out exactly at t + transit time. Also called a pipeline delay.
Counterintuitive behavior
When policies assuming a particular solution yield unexpected, surprising or paradoxical results that are very different from those intended or expected. Often, as troubles increase, well‐intentioned but flawed efforts are intensified, which reduce improvement or worsen the problem instead of improving the situation. See also policy resistance.
Co‐flow
A parallel stock‐and‐flow structure that mimics a primary stock‐and‐flow structure in which the co‐flow structure models an attribute or characteristic of the contents of the primary structure.
Cyclical behavior
See oscillation.
Dampening
A decrease in the magnitude of movements from an average value, typically in oscillations. Also a system response that is less than is seemingly implied by input variables.
Decision function
A policy statement that determines how information is used to generate actions for managing the system. Also the algorithm used to transform incoming information into a stream of decisions over time.
Delay
A phenomenon in which the effect of one variable on another does not occur immediately. A process by which the output lags behind its input in time.
Delta time
See solution interval.
Diffusion structure/behavior
A structure/behavior that describes the spread of products, ideas or beliefs, typically based on a model of new product adoption developed by Frank Bass.
Dimensional analysis
A procedure that checks for unit consistency in equations.
Disaggregation
The opposite of aggregation. Disaggregation is done to separate variables into components that do not have close enough effects on system behavior to be modeled with a single variable.
