Multi objective optimization problem

Hello everyone,

I'm trying to find the right way to set up on Matlab the optimization problem that I have to manage with. It is the first time that I have to solve a problem like this and I am not sure how to proceed.

Looking at the image attached, I want to find the three parameters BF_bay1, BF_bay2 and BF_bay3 that minimize the values of R_A, R_B, R_C, R_D and weight. The terms R_A, R_B, R_C and R_D are vectors with length [1;720], the weight is a single parameter and I know the "first try" values of these terms.

The terms BF can vary from 0 to 1.

I think that is a problem of multiobjective optimization so I can use fgoalattain but I don't know how to set up it.

I hope that anyone can give me a suggestion. Thanks.
