Abstract:
|
We consider the situation in which a relatively large portion of data that serves as a basis for a monitoring scheme changes with time. Unlike in the case of conventional control schemes, in which new data records generally pertain to monitored items that have been introduced recently, in our case a new data record can affect information related to items introduced at earlier stages. Situations of this type are common, for example, in the area of warranty data monitoring, in which incoming repair records from the field typically provide information related to reliability of earlier product vintages. In this paper we introduce a methodology for monitoring data of this type and discuss an example related to analysis of component failure rates based on warranty data.
