Simulation¶
Replicate outcomes of uncertain process
Works with any distribution
- Regular/irregular
- Continuous/not
- Normal/not
Requirements¶
Distributions for key parameters
May be observed, estimated, assumed, or guessed
Steps¶
-
Create a valuation model
-
Identify most significant uncertainties
-
Tornado diagram
-
Choose distributions for uncertainties
-
Model distribution of outcomes
-
Set up decision rules for exercising flexibility, to ensure that it is right decision to exercise flexibility
For eg: “Expand if observed demand > Capacity over 2 years. But don’t expand towards the end of life”
Flexibility Types¶
Flexibility “in” system | Flexibility “on” system | |
---|---|---|
Feature design to enable system to evolve easily | Nothing to do with design | |
Example | Building foundation to support additional floors in future | Abandon project Delay project |
