Determining Grade Structures of Network of Highway with Program Method of Multiple Objectives

A disposition reasonable grade structure in program network of highway is one of major steps. The requirement of many desired objectives must be achieved for disposing the reasonable grade structures of highway network. This paper solves the optimization problems of the grade structures of highway network with program of multiple objectives. The method can consider comprehensively the relations and restrains each other and as far as possible satisfy the actual requirements. For this reason, it is an ideal optimization method of the grade structures of highway network.
