What are the differences between influence diagrams and decision trees?

Influence diagrams are graphical representations that show the relationships between decisions, uncertainties, and objectives. Decision trees, on the other hand, are a flowchart-like structure that helps in making decisions by outlining different possible outcomes based on various choices.

Can you give me an example of when to use each?

Sure! Use an influence diagram when you need to visualize complex relationships and dependencies, like in strategic planning. Use a decision tree when you want to evaluate specific choices and their potential outcomes, such as in risk assessment.

Which one is better for risk analysis?

It depends on the context. Decision trees are often better for straightforward risk analysis because they clearly outline possible outcomes. Influence diagrams are better for understanding the broader context and interdependencies.

Are there any software tools that can help with these?

Yes, there are several tools available! For decision trees, you can use software like TreePlan or Lucidchart. For influence diagrams, tools like Vensim or AnyLogic are popular.
