### Conclusions

- Practitioner in modeling:
- works on given large models that change in the future
- is not an expert of
*every* intricacy of
complex simulation
- has not enough time to go to the bottom of every
problem
- must use every help she can get -
*even* from
mathematics

- Advantage of theory-based models:
- precisely specified
- structurally simpler
- Simulink implementation completely straightforward

- Advices addressing different listeners:
- colleagues teaching modeling:
**Stress the use of mathematical models!**

- graduates starting in the industry:
**Tell your bosses that mathematical
preciseness pays off in the long run!**

- people creating simulation tools:
**Use mathematical models yourself - and
pass them on to your users!**
