[Help-glpk] fraction with vars

[Kasper Tordrup]

Hi guys

I have a problem with calculating a fraction, the reason is that both the nominator and denominator are variables.

So I am looking for some way to make this linear:

x_suj = p_s * (y_suj/w_su) or well just find what this fraction is: y_suj/w_su

where p_s is a constant, x,y and w are integer variables. and I also need to avoid the division with 0 problem.

Anyone know some tips/tricks for this?

Regards,

Kasper
