The entropy-directed algorithm needs manual intervention to construct fault isolation strategy,and it is ofεhigh computation complexity.Theoretical analysis and experimental results illustrate that the entropy indirected algorithm remedies such deficiency. The MFIT of the strategy by this algorithm is about 38% less than that by the entropy- directed algorithm under the assumption of unequal fault rate.

It is now well established that system outages are caused more due to software faults than due to hardware faults. Software aging is a kind of software fault which is a phenomenon that the state of the software system degrades or crashes with time. This phenomenon exists in all kinds of applications that run a log time.

软件故障所引起的系统运转中断远远高于硬件故障，而软件老化是软件故障的一种，它是指软件运行一段时间之后性能下降甚至崩溃的现象，这种现象广泛存在于各种长期运行的软件之中。

This text has analyzed the common malfunction of the asynchronous motor at first. And then it, which is based on symmetrical weight theory, has drawn accurate criterion of the trouble of the motor, confirmed the protective measures of different troubles. Finally, it has realized kinds of protection functions, such as short-circuit protection, rotate-stop protection, over-heat protection, negative current protection, zero current protection, low-voltage protection, over-voltage protection, overlong start-up time protection, frequent start-up protection, lock protection of electric leakage and so on.
