A Bayesian Semiparametric Analysis of the Reliability and Maintenance of Machine Tools
Jason R. W. Merrick, Refik Soyer, Thomas A. Mazzuchi · Technometrics · 2003
A Bayesian semiparametric proportional hazards model is presented to describe the failure behavior of machine tools. The semiparametric setup is introduced using a mixture of Dirichlet processes prior. A Bayesian analysis is performed on real machine tool failure data using the semiparametric setup, and development of optimal replacement strategies are discussed. The results of the semiparametric analysis and the replacement policies are compared with those under a parametric model.
