How to linearize function?
To be able to use following objective function in CPLEX, we must first linearize the function, because CPLEX cannot solve function that are non-linear in the decision variables. xj; yij and yjk are decision variables. Who can help? Taking the square root is not good, since this causes a too big input value for fj.
function, see attachment.
Thank you in advance.

You "linearize" a function by replacing it with a linear approximation, the one give by the tangent line or plane to its graph. Here, the non-linear terms that need to be replaced with tangent approximations appear to be the square roots.
