Need help for choosing B-school

Hi Everybody

I'm new here and just want to ask for some suggestions from you guys.

I'm currently studying in the US. College junior. Studying Supply Chain  and Entreprenuership ( double major) My school's supply chain program ranked pretty high in the US (top 15) and I'm in school's honors program

Current GPA 3.6 One academic paper ( english, top journal, supply chain related) Writing my honors thesis now. Done one consulting project with my professor for a fortune 500 company. Currently doing co-op for a medium sized company.  Have ran a student-run company freshman year

I'm looking in to MS degree in supply chain management / operations management and operations research. Recently, I came to this forum and found out that there are actually PHD degrees for my field. I don't know if my backgournd is good enough to apply for a PHD from a top 30 b-school.

Thanks and congradulations to those who got accepted by my dream schools~~  

Yeah, I'm really really interested in green supply chain. It is hard but it's very exciting when you discover the answer of the hypotheses/topics you are interested in. At the same time, by doing a co-op, I came up with even more questions that I want to solve by doing possible indepent studies.

I did, he gave me all kinds of suggestions. Go do a master of economics ( that's what his own field), go do a master of international affairs ( I told him I'm interested in consulting), go do a phd, go to a top school for a semester, take some more advanced courses ( I'm thinking about this coz I have one semester open in my senior year ). So now, I'm lost. To  many choices, I can't do all of them.
