利用石油产品调合关系设计能力验证方案
发布时间:2019-07-01 12:06
【摘要】:正能力验证是国际通行的实验室及其监管者实现质量控制的有效方法,串通现象的存在使能力验证计划实施的结果存疑,严重困扰着组织者、参加者以及实验室的客户。本文利用石油产品调合规律,设计了一种能够尽可能多的向能力验证计划参加者分发不同样品的方案以避免串通现象。验证结果表明:依据两组分调合的数学关系,利用稳健回归技术等手段能够有效表征实验室的检测能力,避免串通。
[Abstract]:Positive capability verification is an effective method for internationally accepted laboratories and their regulators to achieve quality control. The existence of collusion makes the results of the implementation of the competency verification plan suspicious and seriously puzzles organizers, participants and laboratory customers. In this paper, based on the blending law of petroleum products, a scheme is designed to distribute as many different samples as possible to the participants of the capability verification program in order to avoid collusion. The verification results show that according to the mathematical relationship of the blending of the two components, the robust regression technique can effectively characterize the detection ability of the laboratory and avoid collusion.
