I m working on use of fuzzy logic in water quality indezing...
It really depends on what your data are like. But I would start with triangular membership functions. They are the simplest to control and are normally very effective.
As sir told it depends on the data set. There is no thumb rule for selection of appropriate MF. Instead you can try all MFs and prove which suits best for your data set. That is the ideal way to proceed I guess.
Thank you.

Thanks a lot Satheesh kumar n R/ Mahmoud Omid sir.....
It depends on the system to be controlled or the data set. In general, sigmidal MFs are very effective.
