大数据驱动质量安全风险管理示例
理化、生化质量指标的联合概率分布(山峰)的改进前和改进后对比。
山峰变陡峭,意味着在大数据驱动下,贝叶斯方法更新的弧线参数其不确定性降低,从而使得整体风险降低。
样本容量的上升、使得山峰陡峭度加剧,意味着数据规模的增大有利于风险进一步降低。
QIA = Quality Improvement Activity
中药材检测时间、技术水平与质量的权衡
在技术水平充足情况上,在质量和时间之间具有最优平衡区间。
质量和技术水平之间具有较严格的最优平衡曲线。
时间和技术水平之间没有明显的因果关系。
结论:在技术水平充足情况下,减少时间亦可以实现最优质量,论证了快检技术的优势和价值。
NDS = Non-Dominated Solution
GNDS = Global Non-Dominated Solution
