摘要
结合工程项目质量控制的特点，分析了现行管理图判定标准所存在的问题，指出控制图判定标准的理论依据中所指的小概率事件存在含糊不清和判定尺度不同等现象，给控制图的判定带来困难．在现有基础上，明确了小概率事件的判定界限，推算出各种情况下的判定标准，给出计算判定标准的公式．
In combination with the characteristics of project quality control, this paper firstanalyzes the existing problems of current judgement rules of control charts. It especiallypoints out the ambiguousness and different Judgement standards in the judgement theory.On the present basis, the judgement line for little probability events is explicated, and then,the judgement standards are reckoned for different situations, finally, calculating formulaeof the judgement standards are given.
