摘要

在一个大型的安全评估团队中,需要一种标准的方法来处理常见的故障原因,以便在一系列项目中遵循一致的方法。模型的要求是:可接受性、适用性、灵活性和一致性。结果发现,通过将ß-因子模型与极限值相结合,并允许β值随着对CCF的保护增加而降低,有可能满足模型的目标。还包括一个使用该模型的示例。

A practical method of common cause failure modelling

The need arose in a large team of safety assessors for a standard method of treating common cause failures to be defined so that a consistent approach could be followed across a range of projects. The requirements of the model were: acceptability, applicability, flexibility and consistency. It was found by combining the ß-factor model with limiting values and allowing the value of β to reduce as the protection against CCF increases, it was possible to meet the objectives of the model. An example of the use of the model is included.
