A Simple Method for Land Grading Computations and its Comparison with Genetic Algorithm Method

This paper reports the development of a new method for land grading computation having time saving and simplicity advantages. The conventional method uses the trial and error process to determine the desired cut-fill ratio, which is cumbersome and time-consuming. In developed method, the trial and error process is not necessary. Instead, the Excel Solver was applied to determine the plane equation of land grading, and minimize the earthwork volume based on a desirable cut-fill ratio. Then, results of the new method for three data sets were compared with the conventional and genetic algorithm (GA) methods. In all of the data sets, results of the new method were better than two other methods. The cut-to-fill ratio and cut volume were less in new method than others.
