Hi
My problem contains two LP model, LP1 and LP2 which be solved separately. The variables of model LP1 and LP2 are defined as x[i,j] and y[i,j], respectively where (i,j) in E, and set E within (V cross V); set V := 1..n; I want to use the optimum solutions of LP1 and LP2, in third LP model LP3 as parameters. For example, LP3 contains these commands: param x{(i,j) in E}; param y{(i,j) in E}; var z{(i,j) in E}; maximize Val: sum {(i,j) in E} (x(i,j)+ y(i,j))* z(i,j); How should I save the optimum values of x[i,j] and y[i,j] such that they can be read in LP3 as parameters. Thanks in advanced Shaghayegh
