把工厂日常用到的计算公式集中到一页:合格率、直通率、OEE、节拍、产能、不良损失、Cpk 相关计算等,每个公式配计算口径与示例,避免同一个指标在不同部门算出不同结果。Everyday factory formulas collected on one page: yield rate, first-pass yield, OEE, takt time, capacity, defect cost loss and Cpk-related calculations, each with its calculation convention and a worked example, so the same metric is no longer calculated differently across departments.
