系统动力学有各种各样的“封底”管理应用。它们是一个强有力的工具:

*Teach [[system thinking]] reflexes to persons being coached

*Teach [[system thinking]] reflexes to persons being coached 向受训者传授系统思维反射

 

 

 

*Gain qualitative insight into the workings of a system or the consequences of a decision  对一个系统的运作或决策的结果获得定性的洞察

*Recognize archetypes of dysfunctional systems in everyday practice

# Objective: study of a crank-connecting rod system.<br /> We want to model a crank-connecting rod system through a system dynamic model. Two different full descriptions of the physical system with related systems of equations can be found  [[Piston motion equations#Position|here]] {{in lang|en}} and [[:fr:Système bielle-manivelle#Équations horaires|here]] {{in lang|fr}}; they give the same results. In this example, the crank, with variable radius and angular frequency, will drive a piston with a variable connecting rod length.
