A Note on Internal Control Systems with Control Components in Series.
建立了一个串联控制组件的控制系统可靠性模型，发现增加控制组件可能提高或降低输出可靠性，取决于组件特性参数，并指出Bodnar的结论在正确建模下不成立。
Abstract ABSTRACT: This paper presents a reliability model of a control system with control components in series. The results show that output reliability may increase or decrease as new control components are added to the series, depending on the characteristic reliability parameters of the control components. The results are compared with Bodnar's [1975] results that led him to the paradoxical conclusion that fewer control components are better than more in a serial system. It is observed that no such paradox exists when the controls are modeled properly.
