A comparative study to estimate costs at Bombardier Aerospace using regression analysis

The purpose of this research is to develop a target cost model for the Main Landing Gear at Bombardier Aerospace. This will offer a cost understanding at the early conception stage. The study uses a comparative analysis between a linear and a non-linear parametric model in order to determine which estimation method will increase the credibility of the cost estimate. The reliability of the models will be validated by two different methodologies to determine which parameter(s) become significant and will therefore be used to determine the cost. These methodologies are the analysis of variance and path analysis. It was found that the non-linear regression analysis achieves a lower level of error when comparing it to the linear regression
