and EAAT

2. Outline
• Research motivation
• Value networks with e3value
• Probabilistic value networks
• Why
• The method
• Interpreting results

3. Research motivation: why value networks?
The project: evaluating business ideas in
Stockholm Royal Seaport

4. Research motivation

6. Research motivation
How to compare qualitative models?

7. Research motivation: why value networks
We need a formal approach to evaluate business scenarios.
We want to analyze risk/profitability outside the formal
boundary of a single organization.

8. E3value
• A graphical approach to model a value network
• Uses simple arithmetics in the background
• Use cases used to define calculation logic

11. Probabilistic approach
The problem with incomplete data and prediciting the future.
For example:
Money for selling a house: 20 -25 million (20% difference)
Number of ride sharing passengers 5-25%

12. Probabilistic approach: EAAT tool
Based on UML and OCL with an inference engine.

13. Extending e3value: the metamodel

14. Extending e3value: the object model

15. Extending e3value: calculation results
Mean value = 10037 Mean value = 4815055 Mean value = 4918

16. Conclusion
• The lack of knowledge may have a negative impact on the
quality of the analysis outcomes
• Our approach is a viable alternative to mean value based
analysis and shows risk
