Thank you very much from your response. This question was because of my previous problems about equilibration the box that I sent it with subject "equilibrium for box of simulation". When I equilibrate solvent and additives separated and then add to surfactant and after that equilibrate totally, there are not previous problems and I wanted to know that this method is correct?

I made one box with only solvent and one box with only additives and equilibrated them little separable for better placing into the box, and then made one box with surfactant and then placed box of solvent and additives (that before I had equilibrated them separable) in the box of surfactant (by genbox) and equilibrated it totally.

Maybe. It's hard to tell. Note that when you post the same thing four times and do not get a reply, it's usually due to the fact that it's hard for us to figure out what's going on.
I don't know what your goal is but your approach is a bit hard to comprehend as written. One can usually build a multi-component system rather easily with a few invocations of genbox -ci -nmol, but then too, I don't know if you need some particular configuration (surfactant micelles?) or if random positions will suffice. Prior equilibration of solvent is probably a good approach.
