Optimize Models of Line Choice for Rebuilding Ancient Highway with Arithmetic |
| |
| Abstract: | In this paper, retrofit of the aligments of worn highways is analyzed. The principles of spline approximation and fitting approximation are applied synthetically, and the objective functions of optimizing models are founded for rebuilding worn highways. To solve the mathematecal programming problems,the numerical means are studied and a Java program is developed to determine the contimuous combined curve parameters meeting the design Specifications. |
