Abstract
The design effort required to complete a project is an important aspect of a project. It impacts the final cost, as well as the lead-time of a project. In this paper, a case study, which is carried out at Pratt & Whitney Canada, a global leader in the design and manufacture of aircraft engines, is presented. A Parametric model is proposed to estimate the design effort required in for a particular department to complete their design phase of an integrated blade-rotor low-pressure compressor fan. In a sensitivity analysis, the model estimation is compared with the actual estimates and the comparison demonstrates that the parametric model results in a good estimation. The analysis further explores the impact of various factors used to develop the parametric model, as well as demonstrates the significance of the proposed modeling methodology.
