一、可靠性预计的目的与作用可靠性预计是产品可靠性设计从定性考虑转入定量分析的关键，也是实施可靠性工程的基础。在方案研究和工程研制阶段，及时地预计系统、分系统或设备的基本可靠性和任务可靠性，并实施“预计──改进设计”的循环，以使产品达到规定的可靠性要求。否
First, the purpose and reliability of the expected reliability is expected to be the reliability of product design from qualitative considerations into the quantitative analysis of the key, but also the basis for the implementation of reliability engineering. The basic reliability and mission reliability of systems, subsystems or equipment are estimated in a timely fashion during the program research and engineering development phases and the “projected-improved design” cycle is implemented to achieve the specified reliability requirements. no
