The failure for causing each module that order is performed thereafter to produce is delivered to next stage, causes fault rate to greatly increase.I.e. certain module is being set
Only Exactly-once in standby life cycle, its mistake produced also can always with equipment throughout one's life, cause the long-term of potential safety hazard
In the presence of.Specific fault rate is calculated as follows：
Assuming that the probability of each module normal work is 0.9, then multiple modules can normal work probability just to be long-pending
Relation, if 3 work in series modules, then normal working probability 0.9*0.9*0.9=0.729, can cause fault rate greatly
Increase.If module work is changed into hierarchical control, normal work rate is independent of each other, and each module is independent, itself work
Finish after exiting and restarting, not restarting would not also influence the normal work of other modules, i.e. error rate to be defined in itself
In the range of, faults itself rate is remained as, the mistake of itself will not be added in other modules, therefore, actually reduces and is
System fault rate.
