You should show the code you have written to try and solve your problem along with the places you are getting stuck and the error messages you are getting.

What is given and what is to be found? Are t and U and W constrained ? is s given? What is the maximum i value?

My interpretation was that Z is the maximum over Ri.
Nirmal

yes Z is the maximum of Ri

Oh, okay. I was thinking it was something (some other equation, or expression) that needed to be maximized. So you're saying it's like this: Z = (the maximum R(i) value over all possible index values for i) - basically Z is the desired answer, and once you know that you should know what values of i, j, m, t, U, and W gave rise to that Z.

You would need GA from the Global Optimization Toolbox. The IntCon argument would be used to specify integer-constraints.

i cannot use the toolbox as the above code would be a sub-part of the code which i'm developing for big task using PSO.

Why would LINPROG have been any better than GA?

not that sort of.. but i have to implement it in the form of a code. thus not possible to use the toolbox.

Well, you Accepted an answer already so people are going to consider teh Question closed. Also, you've announced that you cannot use any black-box solvers like LINPROG or GA. So, there's not a lot of help we can offer.
