Modelling system at early design stage

[dr_mushroom]

Hello,

nice to find this kind of great forum. I am quite puzzled with the task that was given to me: How to model mechatronical system (multidomain) on early product development stage? So, because product is not well defined yet, there are much uncertainties what to model(!)

So, how to select most important variables to model?
How to handle level of imprecision in those kind of models?
how to model multi domain models?

So, as you can see, problem is not very strictly defined. Report should be still about modelling different domains(electric, mechanical, computer science) and handling the uncertainty. So, would you guys have any ideas how to start? even some stupid/clever guesses would help me a lot! Any papers including some of stuff I just mentioned would be great.

Thanks for help,

dr Mushroom

If u r asking about the designing...then u can refer "TOP DOWN" or "BOTTOM UP" approaches based on what information u have initially...
