This study proposes a methodology for predicting product failures occurring due to known failures and causalities. The prediction is based on failure propagation in an integrated model of a product, production process, and quality information (PPQ). This methodology enables a designer to predict new failures. One of the concepts for failure prediction is the PPQ for compiling referring to quali...

High availability is widely accepted as an explicit requirement for distributed storage systems. Tolerating correlated failures is a key issue in achieving high availability in today’s wide-area environments. This paper systematically revisits previously proposed techniques for addressing correlated failures. Using a combination of experimental and mathematical analysis of several real-world fa...
