1, troubleshooting
Eliminating mistakes is the best way to prevent them. Because from the design point of view, it considers possible mistakes in homework and uses error-proof methods to prevent them. This is a method to prevent mistakes and defects from the source, which conforms to the principle of quality economy and is the development direction of anti-fraud.
2. Substitution method
The alternative method is to update and improve the hardware facilities, so that the process does not depend too much on the operators, thus reducing the mistakes caused by human factors (accounting for the part of mistakes). This error prevention method can greatly prevent the low error rate and is a good error prevention method. The disadvantage is that the investment is too large and the errors caused by equipment problems cannot be prevented.
Step 3 simplify
Simplification is to simplify the operation process by merging and cutting. The simpler the process, the lower the probability of operational errors. Therefore, simplifying the process is one of the better error prevention methods, but simplifying the process can not completely prevent human defects.
4, detection
Detection is an error-proof method that automatically prompts when an operation makes an error, which is mostly realized by calculator software and is widely used at present.
Step 5 reduce
From the point of reducing the loss caused by mistakes, that is, reducing the loss to the lowest or acceptable range after mistakes, many intelligent devices have this function to some extent at present.
