Weibull modeling of part modification reliability for the use of return on investment (ROI) estimates
When Bombardier comes across reports from their customers regarding frequent part failures, they investigate reasons for the cause of these failures. If many reports are received, all due to similar faults on the same part, design changes are made to the part to make it more reliable. Once the newly designed parts are available for purchase, Bombardier informs their customers of the part and is often required to provide an expected return on their investment/purchase (ROI) of a new part. ROI is expected since the part is more reliable and thus decreases costs due to flight delays, cancellations, and incidents. The study will focus on ways to improve the ROI given to the customers using concepts related to reliability engineering. The better ROI estimates would give operators more confidence in the results and will result in an increase in new part purchases as well as Bombardier revenue.
