Well dear, as per my knowledge and sources, SIBM or SCMHRDS or SIIB, Pune, provide two year full fledged MBA program and not any part time course as such.

However, yes there is an executive program run by all the institutes for the executives who are seeking to advance their careers. This is a part time course. 

One needs to have minimum 3 years of experience to pursue executive program and classes are run usually on Saturdays and Sundays.

These are among the premier institutes of India and are known for their full course of MBA .

All the best!!
