The schematic diagram of one detection system of addition, such as increased detection system is but that Wuhan laboratory is luminous interior under TSH project
Secrete " Roche " detection device that post provides, device numbering 000001.
S2, it is standardized according to the local unilateral Capability index of each detection system, obtains corresponding mark
Quasi- unilateral side Capability index；
For the quality evaluation in local (for example, Wuhan), configured with local standard, therefore, if it is desirable to right
When local unilateral Capability index under various criterion is compared and counts, need to its unified standard.In this step, first
The first ratio for obtaining standard maximum allowable error and the local limits of error, by the local unilateral Capability index with it is described
The multiplication of first ratio then generates the standard single sided Capability index.
Wherein, the local limits of error include local absolute value error and local percentage error, the standard
The limits of error include standard absolute value error and standard percentage ratio error.The then sheet according to each detection system
Ground unilateral side Capability index is standardized, and obtains corresponding standard single sided Capability index specifically:
If the testing result of the detection system be less than preset first threshold, obtain the standard absolute value error and
The local unilateral Capability index is multiplied with second ratio, generates institute by the second ratio of the local absolute value error
State standard single sided Capability index；
If the testing result of the detection system is greater than or equal to the first threshold and is less than preset second threshold,
The third ratio for obtaining the standard percentage ratio error and the local percentage error, by the local unilateral Capability index with
The third ratio multiplication then generates the standard single sided Capability index.
For example, local absolute value error is 2, local when the inspection result of detection device is less than 40 (i.e. first threshold)
Unilateral Capability index is 0.38, and standard absolute value error is 5, then standard single sided Capability index is 5/ (2*0.38)=0.95.
Preferably, the local unilateral Capability index is generated by following steps:
In response to the unilateral capability evaluation instruction to any detection system, the preset limits of error, preset are obtained
Frame mean value, the detection system are to the average and standard deviation of n inspection result of sample；Wherein, the n inspection result
For the n inspection result nearest with current time, n >=2；
According to the limits of error, frame mean value, average and standard deviation, the original list of the detection system is calculated

Using the minimum value in all original unilateral Capability index of the detection system in the preset period as described in
The local unilateral Capability index of detection system.
It should be understood that the original unilateral Capability index (for example, calculating daily primary) being calculated every time is all successively deposited
Enter in memory.As n=5, then when calculating original unilateral Capability index every time, obtains preceding 5 inspection results and calculate standard
Difference and average value.In addition to this, n can also be not fixed as a constant, and be set as the detection system to the of the sample
One inspection result (i.e. Kaifeng using start) is to the number of current inspection result.
Specifically, in preset moment point, actual date belonging to the moment point is obtained；
When the actual date is consistent with preset date value, original unilateral side all in the preset period is obtained
Capability index；
It is the local single of the detection system by the minimum value in original unilateral Capability index all in the period
Side Capability index.
For example, No. 5, No. 15 and No. 25 local unilateral Capability index progress standards by the detection system of setting monthly
The calculating of change obtains standard single sided Capability index, wherein No. 15 corresponding local unilateral Capability index are this month No. 5 to this month 15
Number all original unilateral Capability index minimum value, similarly, No. 5 corresponding local unilateral Capability index be last month 25 to this
The minimum value of all original unilateral Capability index of the moon 5, No. 25 corresponding local unilateral Capability index are this month No. 15 to originally
The minimum value of all original unilateral Capability index of the moon 25.

If current inspection systems are greater than or equal to the first threshold to the inspection result of sample and are less than second threshold
When value, according to the local percentage error, frame mean value, average and standard deviation, the original list of the detection system is calculated
Side Capability index；Specifically:
The unilateral Capability index of the detection system is calculated according to the following formula:
Cpk1=(AVG1+AVG1*E2-AVG2)/(3*SD)
Cpk2=(AVG2- (AVG1-AVG1*E2)/(3*SD)
Cpk=min (| Cpk1 |, | Cpk2 |)
Wherein, Cpk is the unilateral Capability index of the detection system, and Cpk1 is that the right side ability of the detection system refers to
Number, Cpk2 are the left side Capability index of the detection system；AVG1 is the frame mean value, and AVG2 is the average value, and E2 is
