The dimension in border is classified equipment.
In the present embodiment, which is specifically included: working environment is had the risk for increasing equipment failure occurrence frequency
Sizing of equipment is running equipment under adverse circumstances, for example is run in open-air atmosphere, the equipment to work under strong radiation environment etc.;It will
Working environment is running equipment under general environment, such as factory there is no the sizing of equipment for the risk for increasing equipment failure occurrence frequency
The equipment run in room, good equipment of operating ambient temperature etc..
S206, aobvious recessive classification: for the key equipment and important equipment in classification results, after the failure of tables of equipment one
The dimension of aobvious recessiveness equipment is classified.
In the present embodiment, which is specifically included: tables of equipment one can will be sent out under normal operating conditions by user after failing
The equipment that its existing function has been lost, is classified as dominant equipment;It will tables of equipment one cannot be by after failing under normal operating conditions
The equipment of user's discovery, is classified as recessive equipment.
S207, output classification results: it is directed to key equipment and important equipment, exports the classification knot of the above four dimensions
Fruit, for operation to the equipment of maintenance, then the classification results of the only dimension of equipment criticality exported.
It should be noted that above step S204, S205, S206 and in the absence of successive requirement in sequence, this three steps
Rapid execution sequence is not limited in situation shown in the present embodiment.
