第二次世界大战以后不久,军事工业、商业、交通运输等部门开始大量使用复杂的电气设备。工程师们在改善设备性能,提高其自动化程度,设备系统小型化等方面做了不少工作。但是,由于没有足够地注意可靠性研究,因而出现了机械设备由甲地运到乙地即已损坏,电子设备和元器件在库存期间就已失效,雷达、通讯设备常常不能正常工作等现象,从而促使人们开始注意可靠性的研究。计算机可靠性理论 可靠性一般是用正常工作的概率来定义的。假设一个系统由n个元器件组成,要使系统能够正常地工作,就
Shortly after the Second World War, the military industry, commerce, transportation and other departments began to make extensive use of complex electrical equipment. Engineers have done a lot of work in improving equipment performance, increasing automation and miniaturizing equipment systems. However, due to insufficient attention paid to reliability studies, there was a phenomenon that machinery and equipment were damaged when they were transported from station A to station B. Electronic equipment and components were out of stock during the inventory period. Radars and communications equipment were often unable to work normally. So that people began to pay attention to the reliability of the study. The reliability of computer reliability theory is generally defined by the probability of normal work. Suppose a system consists of n components, to make the system work properly
