In this paper, we research the capacitated fixed facility location problem as manufactures in scale of economy. We relax properly the constraints and add residual cost of production capacity so that keep corporations from choosing excess large production scale. The strategy of location not only meets current requirement for corporations, and also prepares chance for the future. Two equivalent mixed integer programming models are formulated for the problem. A Lagranging heuristic algorithm is also developed to find the approximate solutions of second model for this problem. The algorithm was us...
