Multicriteria optimization of earthwork processes using the method of least squares

The selection of mechanization in the earthwork processes has become a very difficult these days because of availability of variety models of mechanization. To overcome this problem, the multicriteria optimization has become the most popular methods to make the final decision. In this paper, the method of least squares is presented to compare some alternatives of excavators which are commonly used in the fields of construction and engineering. Application of this method is presented with a case study to demonstrate an approach to make a step wise decision from the point of the key criteria of optimizing.
