Statistics Seminars: Identifiability Issues Related to Repairable Systems with Several Failure Modes

Presented by Tim Bedford,

22 February 2002 14:00 in CM221

"A repairable system can briefly be characterized as a system which is repaired rather than replaced after a failure. In the present paper we study systems with more than one component, where to each failure time is associated a unique failing component.
We consider the problem of identifying a model within a given class of probabilistic models for the system. Different models corresponding to different repair strategies are considered: a partial repair model where only the failing component is repaired; perfect repair, where all components are as good as new after a failure; and minimal repair, where components are only minimally repaired at failures. We show that on the basis of single socket data the partial repair model is identifiable, while the perfect and minimal repair models are not.
This is joint work with Bo Lindqvist
