you just missed the QS World MBA Tour, but you should check out their website
www.topmba.com. they list all kinds of schools and can direct you with your search criteria to schools that might fit the best.
Honestly though, I think you need to do the research yourself a bit more. You seem very vague about what you want and only know that it has to be an MBA, part time or online. Well that will cover a ton of schools in CH, EU and other parts of the world.
I m enrolled at HSG (University of St. Gallen) at the moment with the part time option, so are 2 or 3 other members on EF as well. You can PM me if you have questions to that particular program, but I do ask you to please read their website if you are interested first. It is pretty comprehensive.
