SECTION 10.6 REVIEW QUESTIONS

1. What is the key difference between system dynamics simulation and other simulation types?

2. What is the purpose of a causal loop diagram?

3. How are relationships between two variables represented in a causal loop diagram?

Answer 1

Question 1.

The dynamic simulation is modeled in continuous time while the other discrete event simulation is modeled in the discrete-time.

The key difference between dynamic simulation and discrete-event is given as follows:

1. The discrete event is difficult to understand while the dynamic simulation model is easy to understand and transparent to the client.

2. The discrete focus on the detail while the dynamic focus on dynamic complexity.

3. Moreover the dynamic simulation enhances the learning compared to other simulations.

Question 2.

The causal loop diagram is used for modeling the dynamic systems. It is a natural working of the system depiction.

The purpose of the causal loop diagram is to give a representation of the relationship between all the variables and how these variables are linked to each other.

The casual loop diagram shows an issue and its parts diagrammatically that are difficult to understand verbally.

Question 3:

As the causal loop diagram consists of a set of nodes and edges, the nodes are the variable in the casual loop diagram while the edges represent the relationship between two variables.

So, edges are used to represent the relationship between two variables in the causal loop diagram.
