Specific embodiment
Present disclosure is described in further detail below in conjunction with preferred embodiment and attached drawing.Obviously, hereafter institute
The embodiment of description is only used for explaining the present invention rather than limitation of the invention.Based on the embodiments of the present invention, this field is general
Logical technical staff all other embodiments obtained without making creative work belong to what the present invention protected
Range.It should be understood that although hereinafter describing various information using term " first ", " second " etc., these letters
Breath should not necessarily be limited by these terms, these terms are only used for same type of information being distinguished from each other out.For example, not departing from this hair
In the case of bright range, " first " information can also be referred to as " second " information, similar, and " second " information can also be referred to as
" first " information.It also should be noted that illustrate only part related to the present invention for ease of description, in attached drawing and
Not all content.
Fig. 1 is that the flow of the method for the determining Software Reliability Assurance process sophistication of the present invention in one embodiment is shown
It is intended to.As shown in Figure 1, the method for the determining Software Reliability Assurance process sophistication in the present embodiment includes the following steps：
Step S110, according to all compulsory indexes under each Software Reliability Assurance process sophistication index to software
It is tested；
The Reliability Assurance process of software refer to suitable qualitative and quantitative analysis method to the reliability of software into
Row analysis, design, test and the process safeguarded, it is desirable that the various reliability index data collected in test are assessed, and
Demand analysis control during control initial designs is returned, pinpoints the problems and proposes solution, in continuous test and appraisal in cycles
The middle reliability for promoting software systems.In the present embodiment, in order to determine Software Reliability Assurance process sophistication, if setting
A Software Reliability Assurance process sophistication index is done, there are multiple pressures under each Software Reliability Assurance process sophistication index
Property index and recommended index.Wherein, compulsory index refers to perform the necessary index of Software Reliability Assurance, and recommendatory finger
Mark refers to perform the inessential index of Software Reliability Assurance.
In the present embodiment, in order to obtain the comprehensive parameters for evaluating all compulsory indexes, first according to each pressure
Property index tests software.
Step S120, judges whether software meets the corresponding setting condition of all compulsory indexes；If so, it enters step
S130；
Each single item compulsory index has its corresponding setting condition, and it is all to judge whether software meets by test result
The corresponding setting condition of compulsory index may determine that whether all compulsory indexes of the software are equal by software test
Meet.In a kind of optional embodiment, referring now still to shown in Fig. 1, if the software is unsatisfactory for any one compulsory index pair
The setting condition answered, then the Software Reliability Assurance process sophistication for judging the software are minimum.If all compulsory indexes are equal
Meet, then into next step.
Step S130 according to test result and preset mandatory interpretational criteria, obtains each compulsory index
The first parameter；
Tested for a certain compulsory index and the compulsory index be by rear, by test result with it is preset
Mandatory interpretational criteria compares and analyzes, and obtains the first parameter of the compulsory index, which reflects the pressure
The test result of property index.
Step S140 according to the first parameter of each compulsory index and corresponding weight, determines the mandatory finger of software
Mark comprehensive parameters；
Each compulsory index has its corresponding weight, specifically, for all compulsory indexes, according to mandatory finger
Target significance level is divided into three ranks：
(1) index is instructed：It is the guarantee condition that the reliability of software is made to reach higher level to instruct index；
(2) criterion index：Criterion index is the reliability measurement characteristic that should meet under normal conditions；
(3) important indicator：Important indicator is related to the software reliability measurement characteristic that must satisfy.
For all compulsory indexes, according to its significance level, specific level weights are distributed.In a kind of optional implementation
It is respectively that set weights be 5,3,2 for three ranks by engineering practice, i.e., in mode：If compulsory index is to instruct index,
Its weight is 5；If compulsory index is criterion index, weight 3；If compulsory index is important indicator, weight
It is 2.
According to the first parameter of each compulsory index and its corresponding weight, it is weighted, you can forced
Property index comprehensive parameter.It is calculated for example, by using the following formula：
In formula (1), RIL_F be compulsory index comprehensive parameters, ωijFor the weight of compulsory index, Rij_FTo force
First parameter of property index.
Step S150, according to all recommended indexes under each Software Reliability Assurance process sophistication index subsystem
Software is tested, according to test result and preset recommendatory interpretational criteria, obtains the of each recommended index
Two parameters；
Software is tested according to each recommended index, then by test result and preset recommendatory evaluation
Criterion compares and analyzes, and so as to obtain the second parameter of recommended index, which reflects the survey of recommended index
Test result.
Step S160 according to the second parameter of each recommended index and corresponding weight, determines the recommendatory finger of software
Mark comprehensive parameters；
Recommended index can promote or improve the Reliability Assurance condition of software, but be not Software Reliability Assurance must
It works, in a kind of optional embodiment, the weight of recommended index can be set as 1.Then according to each recommendatory
The second parameter and corresponding weight of index are weighted, and obtain the recommended index comprehensive parameters of software, such as pass through
The following formula calculates：
In formula (2), RIL_R represents recommended index comprehensive parameters,For the weight of recommended index, Rij_RTo recommend
Second parameter of property index.
Step S170 is integrated according to the compulsory index comprehensive parameters and its corresponding weight, the recommended index
Parameter and its corresponding weight determine Software Reliability Assurance process sophistication.
According to compulsory index comprehensive parameters and recommended index parameter and corresponding weight, you can determine to calculate
Software Reliability Assurance process sophistication, such as following formula：
RIL=k1RIL_F+k2RIL_R(3)
In formula (3), RIL_F is compulsory index comprehensive parameters, and RIL_R represents recommended index comprehensive parameters, k1It represents
The weight of compulsory index comprehensive parameters, k2Represent the weight of recommended index comprehensive parameters.
The method of the determining Software Reliability Assurance process sophistication of middle offer through this embodiment, can realize to software
The semi-quantitative assessment of Reliability Assurance work overall process, solves model and the side for how measuring and evaluating based on Reliability Engineering
The validity problem of method fills up the blank in the current field, guidance foundation is provided for Reliability Engineering practical work.
In a kind of optional embodiment, Software Reliability Assurance process sophistication index is divided into 5 rule layers and is referred to
Mark, including Software Quality Assurance Techniques evaluation index, software reliability demand analysis technical evaluation index, Design of Reliability
Technical evaluation index, software verification measuring technology evaluation index and software reliability engineering administrative skill evaluation index.It is each
A rule layer index is divided into for several sub- indexs, such as shown in following table：
In upper table, several compulsory indexes and recommendatory finger are included in the sub- index of each rule layer index
Mark, concrete condition is depending on specific software.Each Software Reliability Assurance process sophistication index is illustrated below.
