文献中定义了几种生命衡量标准。给出了具有对数正态寿命的部件的寿命度量。建议将寿命设定在故障率函数的拐点。以这种方式定义的使用寿命是形状参数的函数。这意味着形状参数反映了产品的质量。根据形状参数的取值,可以对部件质量进行分类,部件可以有不同的质量改进或维护策略。
Several life measures are defined in the literature. This paper deals with defining a service life measure for a component with lognormal life. It is proposed to set the service life at the inflection of the failure rate function. The service life defined in such a way is a function of the shape parameter. This implies that the shape parameter reflects the product quality. Based on the value of the shape parameter, the component quality can be classified and the component can have different quality improvement or maintenance strategy.
