The production in steel plant is complex and special, there are many constraints and objectives to be considered in the problem of mid-term production planning, this paper developed a multi-objective and nonlinear model for this problem based on goal programming (GP) and constraint programming (CP), aiming at advancing the profit and productivity of the plant. For give a feasible optimized solution, it relaxed some hard constraints by GP, and did a piecewise linear approximation to the non-linear model with generate algorithm (GA) and linear programming (LP). To test the affectivity and flexibility, this paper did three groups experiments and showed that the method indeed could find the satisfactory solution in acceptable time.
