contribution to computer aided design evaluation utilizing flexible estimation and multiple linear regression analysis Forde, Bruce W. R.


Improvements in design, achieved through a better understanding of fabrication costs, may cause an overall cost reduction for steel structures. A flexible estimation routine, able to satisfy the needs of the particular user, has been developed to provide the mechanism for design evaluation. The functions used by the estimation program are provided by a Multiple Linear Regression (MLR) analysis of data collected by an Information System (IS). The integration of fabrication control and analysis provided by this system permits its implementation in existing environments, and presents an important technological gain for the fabrication process. Traditional design approaches which have relied heavily on experience can now be evaluated and improved in terms of cost competitiveness, prior to or during fabrication, by the proposed MLR strategy.
