Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic flow chart of a method for evaluating a single-side capability of a detection system according to an embodiment of the present invention is shown, including:
s1, responding to single-side capability evaluation instructions of a plurality of detection systems corresponding to a preset inspection item, and acquiring a local single-side capability index of each detection system;
there is a clear scale for the quality of the product, and it is also a problem that the target value deviates too much, in theory. The unilateral index accounts for deviations in target values, primarily to see how much systematic variation is accommodated by the deviated portion.
In step S1, before sending the single-side capability evaluation instructions of several detection systems, the user is required to add a project group (i.e., the calculation group in fig. 2), and only the detection systems in the same calculation group can calculate and compare, for example, if the detection system detects the same project a, the detection system can have instruments in martian, guangzhou, or fertile, the detection systems in these several places are added into one group for comparison. As shown in fig. 3, is a one-sided capability index evaluation of the test items for item TSH. As shown in FIG. 4, a schematic diagram of an added detection system, such as a "Roche" detection device provided by Wuhan laboratories under the TSH project for luminescence but endocrine stations, is shown, with the device number 000001.
S2, carrying out standardization processing according to the local unilateral capability index of each detection system to obtain a corresponding standard unilateral capability index;
for local (e.g., wuhan) quality assessment, local criteria are configured, and therefore, if local one-sided capability indices under different criteria need to be aligned and counted, unified normalization is required. In this step, a first ratio of a standard maximum allowable error to a local maximum allowable error is obtained, and the standard single-side capability index is generated by multiplying the local single-side capability index by the first ratio.
Wherein the local maximum allowed error comprises a local absolute value error and a local percentage error, and the standard maximum allowed error comprises a standard absolute value error and a standard percentage error. Then, the step of performing standardization processing according to the local unilateral capability index of each detection system to obtain a corresponding standard unilateral capability index specifically includes:
if the detection result of the detection system is smaller than a preset first threshold value, acquiring a second ratio of the standard absolute value error to the local absolute value error, and multiplying the local one-sided capability index by the second ratio to generate the standard one-sided capability index;
and if the detection result of the detection system is greater than or equal to the first threshold and smaller than a preset second threshold, acquiring a third ratio of the standard percentage error to the local percentage error, and multiplying the local one-side capacity index by the third ratio to generate the standard one-side capacity index.
For example, when the test result of the detection device is less than 40 (i.e., the first threshold), the local absolute value error is 2, the local one-sided capability index is 0.38, and the standard absolute value error is 5, then the standard one-sided capability index is 5/(2 × 0.38) ═ 0.95.
Preferably, the local one-sided capability index is generated by:
responding to a single-side capacity evaluation instruction of any detection system, and acquiring a preset maximum allowable error, a preset frame mean value, and an average value and a standard deviation of n detection results of the detection system on a sample; wherein the n inspection results are the n inspection results closest to the current moment, and n is more than or equal to 2;
calculating an original unilateral capacity index of the detection system according to the maximum allowable error, the frame mean, the average value and the standard deviation;
and taking the minimum value of all original unilateral capacity indexes of the detection system in a preset time period as the local unilateral capacity index of the detection system.
It will be appreciated that each calculated raw single-sided capability index (e.g., once per day) is stored in memory in turn. When n is 5, then each time the original one-sided capability index is calculated, the standard deviation and mean of the first 5 test results are taken. In addition, n may not be fixed as a constant, but is set as the number of the first test result (i.e. the start of the unsealing use) to the current test result of the sample by the detection system.
Specifically, at a preset time point, acquiring an actual date to which the time point belongs;
when the actual date is consistent with a preset date value, acquiring all original unilateral capacity indexes in a preset time period;
and taking the minimum value of all the original unilateral capacity indexes in the time period as the local unilateral capacity index of the detection system.
For example, 5, 15 and 25 of each month are set, and the local one-side capability index of the detection system is standardized to obtain a standard one-side capability index, where the local one-side capability index corresponding to 15 is the minimum value of all original one-side capability indexes from 5 to 15 of this month, similarly, the local one-side capability index corresponding to 5 is the minimum value of all original one-side capability indexes from 25 to 5 of this month, and the local one-side capability index corresponding to 25 is the minimum value of all original one-side capability indexes from 15 to 25 of this month.
Wherein, the calculating the original single-side capability index of the detection system according to the maximum allowable error, the frame mean, the mean and the standard deviation specifically comprises:
if the current test result of the test system on the sample is smaller than the first threshold value, calculating the original unilateral capability index of the test system according to the local absolute value error, the frame mean value, the average value and the standard deviation; the method specifically comprises the following steps:
calculating a one-sided capability index for the detection system according to the following formula:
Cpk1＝(AVG1+E1-AVG2)/(3*SD)
Cpk2＝(AVG2-(AVG1-E1)/(3*SD)
Cpk＝min(|Cpk1|,|Cpk2|)
wherein Cpk is a unilateral capability index of the detection system, Cpk1 is a right-side capability index of the detection system, and Cpk2 is a left-side capability index of the detection system; AVG1 is the frame mean, AVG2 is the mean, E1 is the absolute value error, SD is the standard deviation;
if the test result of the current detection system on the sample is greater than or equal to the first threshold and smaller than the second threshold, calculating the original unilateral capacity index of the detection system according to the local percentage error, the frame mean, the average value and the standard deviation; the method specifically comprises the following steps:
calculating a one-sided capability index for the detection system 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 a unilateral capability index of the detection system, Cpk1 is a right-side capability index of the detection system, and Cpk2 is a left-side capability index of the detection system; AVG1 is the frame mean, AVG2 is the mean, E2 is the percent error, and SD is the standard deviation.
Wherein the frame mean is a preset constant; or, the frame mean is an average of all test results of the test system on the sample in a preset second time period.
For example, as shown in fig. 5, the first threshold is 40, the second threshold is 500, and when the first threshold is less than 40, the local maximum allowable error is in the form of an absolute value, which corresponds to 5; when greater than or equal to 40 and less than 500, the local maximum allowable error is in the form of a percentage, corresponding to 20%.
S3, arranging the standard single-side capability indexes of each detection system from large to small to obtain the standard single-side capability index of the first 20 percent;
in step S3, a method of twenty-eight law is adopted to obtain the reference value of the global quality parameter. Two eight laws, also known as 80/20 law, Pareto's law, also called barrett's law, Juran's law, Critical Ferule, the most labor-saving law of the least important majority law (Trivial ManyRule), imbalance law, represent the meaning that, in any group of things, the most important of them is only a small fraction, about 20%, the remaining 80%, although the majority, is of secondary importance. Therefore, in the invention, the parameters which are beneficial for the management layer to carry out overall quality evaluation can be quickly acquired by introducing the twenty-eight law.
And S4, evaluating the unilateral capacity of the detection system corresponding to the inspection item according to the standard unilateral capacity index of each detection system and the standard unilateral capacity index of the top 20 percent.
In another preferred embodiment, when the standard one-sided capability index is within a preset first range, the standard one-sided capability index is divided into a first grade;
when the standard single-side capacity index is in a preset second range, dividing the standard single-side capacity index into a second grade;
when the standard single-side capacity index is within a preset third range, dividing the standard single-side capacity index into a third grade;
and when the standard unilateral capacity index is within a preset fourth range, dividing the standard unilateral capacity index into a fourth grade.
Wherein the first range is an interval less than 1; the second range is an interval of greater than or equal to 1 and less than 1.33; the third range is an interval of greater than or equal to 1.33 and less than 2; the fourth range is an interval greater than 2 or equal to 2.
Wherein, when the register corresponding to the standard one-sided capability index is displayed, 1, 2, 3 and 4 can be respectively corresponding to a first level, a second level, a third level and a fourth level, as shown in fig. 6. The first level, the second level, the third level and the fourth level may also be respectively corresponded with 0, 2, 4 and 8, as shown in fig. 7. When the standard unilateral capability index corresponds to a first grade, the detection system is indicated to be in a state of deviation to be improved; when the standard unilateral capability index corresponds to a second grade, the detection system is general in deviation; when the standard single-side capability index corresponds to a third grade, the detection system has good deviation; when the standard one-sided capability index corresponds to the fourth level, it indicates that the detection system is excellent in offset. In practical application, the first level can be marked as dark red, the second level can be marked as light red, the third level can be marked as light green, and the fourth level can be marked as dark green, so that a user can more intuitively acquire required information and can quickly acquire a detection system belonging to the first level or the second level, and corresponding improvement measures can be taken.
Preferably, as shown in fig. 8, in response to a one-sided capability viewing instruction for any one of the detection devices, the standard one-sided capability index and the corresponding rating of the detection device are displayed, and the standard one-sided capability index of the top 20% and the corresponding rating under the corresponding item are displayed. For example, 1.1/2.4 under the column "results" in the figure, 1.1 representing the standard one-sided capability index of the test device, 2.4 representing the standard one-sided capability index of the top 20%; 2/4 under the column "IS" in the figure, 2 represents the grade corresponding to the standard one-sided capability index of the detection device, and 4 represents the grade corresponding to the standard one-sided capability index of the first 20%.
In another preferred embodiment, as shown in fig. 9, in response to a single-sided capability viewing instruction for any one of the detection devices, the standard single-sided capability index of the detection device and the corresponding grade are displayed, and the standard single-sided capability index of the detection device is displayed in the ranking (e.g., 0% -25%, 25% -50%, etc.) of the standard capability indexes of all the detection devices. For example, the column "result" in the figure represents the standard single-sided capability index of the detection device, and the column IS represents the grade corresponding to the standard single-sided capability index of the detection device.
In step S4, the evaluating the single-sided capability of the detection system corresponding to the inspection item according to the standard single-sided capability index of each detection system and the standard single-sided capability index of the top 20% is specifically:
when the standard single-side capacity index of the detection equipment corresponds to a first grade or a second grade and a third grade and a fourth grade corresponding to the first 20% of standard single-side capacity, sending out a prompt needing individual improvement;
when the standard single-side capacity index of the detection equipment corresponds to a first grade or a second grade and the first 20% of standard single-side capacity corresponds to the first grade or the second grade, sending a prompt needing to be improved together;
and when the standard unilateral capability index of the detection equipment corresponds to the third grade and the fourth grade, sending out an unbiased prompt.
For example, when the single inspection apparatus and the standard single-side capability of the first 20% correspond to the grade ratios of 1/3, 1/4, 2/3, 2/4 and 3/4, a prompt for individual improvement is issued, so that the overall offset quality of the inspection item corresponding to the item is proved to be better, and the offset quality of the single inspection apparatus needs to be improved; when the grade ratio of the single detection device to the standard single-side capacity of the first 20% is 2/1, 1/1, 1/2 and 2/2, sending a prompt that the common improvement is needed, wherein the prompt shows that the overall offset quality of the detection item corresponding to the item needs to be improved, and the offset quality of the single detection device also needs to be improved; when the grade ratio of the single detection device to the standard single-side capacity of the first 20% is 3/1, 4/1, 3/2, 4/2, 4/3, 3/3 and 4/4, an undistorted prompt is sent out, which indicates that the deviation quality of the single detection device is better, and the overall deviation quality of the detection item corresponding to the item needs to be improved.
Besides the standard steady state index of a single date of a single detection device, the historical standard steady state index of a plurality of dates of the single detection device can be checked, and the method further comprises the following steps:
responding to a historical unilateral capability viewing instruction of any detection device, and displaying a plurality of latest N standard unilateral capability indexes and corresponding grades of the detection device; wherein N is more than or equal to 5;
arranging the N standard single-side capability indexes according to the time sequence, and counting the number of X standard steady-state indexes belonging to a first level or a second level from the last standard steady-state index; wherein there are no consecutive s of the X standard steady-state indices that belong to a third or fourth level; wherein X is more than or equal to 1, and s is more than or equal to 1.
For example, as shown in fig. 10, the "cumulative number of times" is the number of X standard steady-state indexes belonging to the first rank or the second rank. Assuming that s is 3, accumulation is performed from the last standard steady-state index (corresponding to time 2018.4.25), the standard steady-state indexes belonging to the first rank or the second rank are counted, and when there are 3 or more consecutive third ranks or fourth ranks, accumulation is stopped, and the number of times of accumulation is saved.
For the local manager, it can also obtain the number of detection systems at each level and the average of the levels, and can analyze the quality of the detection systems of the local company from multiple dimensions.
Based on the above scheme, upper management personnel can not only obtain the quality assessment condition of a single detection system, can also carry out comparison of a plurality of detection systems through standardized unilateral ability index, avoid local unilateral ability index standard non-unity and can't carry out mutual comparison and statistical analysis, thereby can't provide global quality assessment result for upper management personnel, and can learn the quality of all check out test set that this project corresponds fast through representative first 20% standard unilateral ability index, and is convenient and fast, therefore, the clothes hanger is strong in practicability.
