Hazard Rate Models For Early Warranty Issue Detection Using Upstream Supply Chain Information, Chongwen Zhou Jan 2011

Hazard Rate Models For Early Warranty Issue Detection Using Upstream Supply Chain Information, Chongwen Zhou

Wayne State University Dissertations

This research presents a statistical methodology to construct an early automotive warranty issue detection model based on upstream supply chain information. This is contrary to extant methods that are mostly reactive and only rely on data available from the OEMs (original equipment manufacturers). For any upstream supply chain information with direct history from warranty claims, the research proposes hazard rate models to link upstream supply chain information as explanatory covariates for early detection of warranty issues. For any upstream supply chain information without direct warranty claims history, we introduce Bayesian hazard rate models to account for uncertainties of the explanatory ...
