S9 finds these input datas for identified each group of test input data from historical production data library
Corresponding response process data, the comparison foundation of the test output data as tested software system（Or as desired output
Design considerations）.
The key technology step of specific implementation is explained as follows, as shown in Figure 2：
(1) step 1：The data near boundary value in historical data are found as possible.If boundary value search criterion is excessively
Harshness, qualified data can be reduced；Condition is relaxed, and qualified data may be excessive.When initial, search criterion setting
It is loose as possible, make that condition and range is gradually harsh, approaches boundary value in step 3.This certain boundary value querying condition is set
Set the measurement error it is also contemplated that hardware device.
(2) step 2：The data occurred near boundary value in the historical data of actual device production are uncertain, to be arranged
Except distortion data.Single invalid data may have a lot of reasons generation（Noise, distortion etc.）, so continuous data segment is needed,
Consecutive numbers is more difficult to look for more greatly, but cannot be too small（Continuous invalid data number lower limit is at least 3, rule of thumb, continuous data
Number lower limit set value can be increased according to industry data experience adjustments）.
(3) step 3：If the continuous invalid data section found is excessive, condition can be changed harsher so that data
Outcome quality higher.
(4) step 4：For each invalid data section, excavating all continuous process with this invalid data section has
The data of the historical data of pass, local time's section are abundant as possible, and data collection cycle is short as possible.The history number of process industrial production
According in library comprising for many years can automatic data collection, can automatic data collection collection period be usually the second grade, classification etc., in real time
Database is main source, needs whether inspection data is distorted in practice（Measuring apparatus failure, noise jamming etc. cause）, but very
May without it is integrated it is relevant can not automatic data collection, can not automatic data collection（Such as artificial analysis data）Collection period
Time is generally longer, in this case, needs to find the historical data bases such as corresponding relevant artificial chemical examination, can be from Subscriber Unit
It goes to excavate in the various data archivals of multiple departments, relevant information library etc., the method that disparate databases preserve is different, need to be to original
The production history database of beginning is processed, and carries out targetedly cutting, integrated association process.
(5) step 5：From this invalid data section（It was likely to be accident condition at that time）Data are past one by one in chronological order
It is pushed forward, finds valid data（Because device production is usually nominal situation, it can generally be pushed forward valid data）, but it is instantaneous
Valid data cannot function as nominal situation data, so the continuous process data before judging this valid data point whether
Legal, if being continuous valid data section, last group of data therein are as nearest valid data.
(6) step 6：First group of data of the subsequent continuous invalid data section of nearest valid data section can be used as non-recently
Method data.
(7) step 7：Under normal circumstances, the accident process data that process industry production scene occurs are generally seldom, but
These data are but very precious for on-the-spot test.Data mining cost may be higher, invalid data that can be as needed
Detail pointedly excavate, to reduce excavating cost and excavate as far as possible abundant.Here it especially reminds：Accident conditions,
Go into operation, stop work, process program handoff procedure it is medium be easy include invalid data.
(8) step 8：Many commercial plant long-time stable normal operations, invalid data is seldom, if from existing whole
The invalid data of needs is can not find in production history database, then the historical data of manufacturing parameter can be counted in this case
Maximum value and minimum value, these maximums, minimum values also largely reflect the number of this commercial plant actual production in fact
According to range and business characteristic, can using the maximum and minimum value of historical data as the design of the input data of border value testing according to
According to.
(9) step 9：Can maximum, the corresponding historical process data of minimum value and corresponding work information, judgement be excavated make
To test input data.
(10) step 10：For each " nearest valid data " and " nearest invalid data "：Excavate corresponding history life
Process data is produced, according to the production status of relevant history production process data reflection, analyzes the influence degree produced to user
And whether caused accident process is controllable, judgement could be as the input data of on-the-spot test（In practice, user's production technology is needed
Expert participates in this step work, and need to examine the input data that rear can be used as on-the-spot test by user's production safety department）.Generally
In the case of, choose the input data of nearest valid data and the controllable nearest invalid data in part of risk as on-the-spot test.
(11) step 11：For the input data of fixed border value testing, this is found from production history database
Response process data corresponding to a little input datas, the comparison foundation of the test output data as new tested software system
（Or the design considerations as desired output）, corresponding comparison can be carried out with the process data of old software processing in this way, for phase
Same input data can more clearly quantify the Quality advance degree of the relatively old software of the new tested software system of comparative evaluation.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
