Abstract: Reliability and durability are key metrics defining automotive product competitiveness. Establishing a market-oriented target-setting system for reliability and durability, providing a methodological reference for reliability and durability development objectives definition. The methodology is based on reliability and durability foundations, reliability and durability metrics target established metrics, the stress-strength interference model, B10 life, and the bathtub curve of product failure rate over the entire life cycle. It introduces a statistically-integrated linear regression attribute model for reliability target prediction. By utilizing after-sales market data analysis and explicitly accounting for the impact of new technologies, new platforms, and new equipment on the reliability target of incidents per thousand vehicles (IPTV) during actual product development, a comprehensive process and methodology for establishing reliability and durability targets IPTV based on market after-sales data is formulated. Through a case study using an enterprise's after-sales data, practical results demonstrate that the final next three-year reliability IPTV target is set at 58.5. This represents a 21% improvement in reliability-driven product competitiveness compared to the current level. This target effectively balances the requirements for enhanced product competitiveness with development cost control imperatives.
