10 Questions
What do descriptive models aim to represent?
How variables interact and how problems are generated
Which statement about system dynamics (SD) models is correct?
SD models are descriptive in nature
What is the difference between continuous and discrete dynamics in models?
Continuous dynamics can change at any time, while discrete dynamics change at pre-defined points in time
Which type of equations are used to represent continuous-time models?
Differential or integral equations
What is an example of a variable that exhibits continuous dynamics?
Air temperature
Which type of models aim to find the 'optimum' decision under a set of constraints?
Prescriptive models
What is an example of a variable that exhibits discrete dynamics?
GPA of a student
Which statement about system dynamics (SD) models and time horizons is correct?
If the time horizon is long enough, SD models can assume time-continuity
Which type of models represent how variables interact and how problems are generated, but do not provide solutions?
Descriptive models
What type of equations are used to represent discrete-time models?
Difference equations
