METHODS AND SYSTEMS FOR ROOT CAUSE ANALYSIS FOR ASSEMBLY LINES USING PATH TRACKING

Methods and systems for performing root cause analysis for an assembly line including a plurality of nodes using path tracking. One method includes receiving tracking data identifying a subset of theplurality of nodes processing a product produced by the assembly line and receiving approval data associated with the assembly line identifying whether each product produced by the assembly line failsan approval metric. The method also includes enumerating a plurality of paths through the assembly line based on the tracking data and determining a failure rate for each of the plurality of paths based on the approval data. In addition, the method includes identifying a malfunctioning path included in the plurality of paths based on the failure rate for each of the plurality of paths, identifying a malfunctioning node based on the malfunctioning path, and performing an automatic action to address the malfunctioning node. 用于使用路径追踪针对包括多个节点的装配线执行根本原因分析的方法和系统。种方法包括：接收追踪数据，所述追踪数据标识所述多个节点的对由装配线生产的产品进行处理的子集；以及接收与装配线相关联的批准数据
