In this lecture, we discuss how to implement two types of delays (fixed delays and smoothing delays) in stock-and-flow diagram dynamical systems models using two System Dynamics Modeling tools – Vensim PLE (by Ventana Systems) and Insight Maker. Along with covering fixed delays and smoothing delays, we also introduce higher-order smoothing delays (which are a type of delay in between the two other purer forms of delays) and some functions for perturbing systems (pulses and steps).
