一位美国海军发言人引用1973年的国防部经费估算时,提出了一个非常明显的情况,即电子设备的可靠性有了提高,维护更加容易。在810多亿美元的预算中,有153亿用于电子设备。值得注意的是,这笔费用的三分之一强(54亿美元)耗费在系统的维护和支援上。 上述这种令人生畏的统计数字是系统的复杂程度日益提高的直接结果。现在要求固态系统比以往任何时候工作得更多、更快、更好、更省。随着性能参数的急剧增加,即使概率很小的故障率也会大大增加总的系统停机时间。 因而,自动化测试就成为能制止预算膨胀的一个主要因素,自动化测试指的是人为干预极小的,快速分析和查出部件、装置、分系统以及系统故障的方法。
When quoting the Ministry of Defense funding estimate in 1973, a U.S. Navy spokesman made a very clear case that the reliability of electronic equipment has been raised and maintenance easier. Of the more than 81 billion U.S. dollars, 15.3 billion are for electronic equipment. It is worth noting that more than a third of this cost ($ 5.4 billion) is spent on system maintenance and support. Such daunting statistics as above are the direct result of the increasing complexity of the system. Now require solid-state systems to work more, faster, better, and save more than ever before. As performance parameters increase dramatically, even a low probability of failure rate can significantly increase total system downtime. As a result, automated testing is a major factor in stopping budget inflation, and automated testing refers to methods that minimize the need for human intervention to quickly analyze and locate components, fixtures, subsystems, and system failures.
