Monitoring product reliability and supply chain logistics in warranty data

In this paper, we show how warranty data may be used to monitor the distributions of time spent by the product in the supply chain and its time to failure after reaching the consumer using simulated data. In our proposed modeling method, we estimate the parameters of the two distributions based on available warranty data that are collected periodically. Standard I-MR charts in statistical process control are used in monitoring the parameters that affect supply chain and product reliability.
