Introduction
Since the flawed software delivery, user needs change, the environment changes, the software often requires maintenance, GB/T 8566-
2007 "Information technology - Software life cycle processes," pointed out the software maintenance software life cycle has become an important part.
GB/T 16260.1-2006 "Software engineering - Product quality - Part 1. Quality model" includes software maintenance statements.
GB/T 29834 with reference to this part of GB/T 16260.1-2006 maintenance statement proposed measure and measure the maintainability index
formula. The development side, the demand side, the quality control manager and third party reviews before the index system based on the definition of maintenance quality requirements, evaluating software products
Maintenance, maintenance of measuring the quality of the case or for other purposes. This section applies to all types of systems have maintenance requirements and software, does not apply
"Single-use" systems and software or during use without change.
The main users of this standard is expected to include.
a) software suppliers, when.
1) to declare maintenance of software product characteristics;
2) maintenance control characteristics declared its own assessment of software products and systems;
3) maintenance of software products related to the design and implementation time;
b) for the maintenance of the certificate of conformity or a third-party evaluation agencies mark when tested;
c) the potential demand-side when.
1) procurement of software products for the upcoming maintenance requirements and existing product descriptions compare information;
2) the need for product performance further improvement or improvement of products and potential errors made the necessary changes, the actual operation
Differences in environmental and procurement environment;
3) inspection maintenance requirement is satisfied.
GB/T 29834.1 "System and Software Maintenance - Part 1. Indicator System" gives the measure of the index system maintenance,
GB/T 29834.3 "Systems and Software Maintenance - Part 3. Test methods" describes test methods maintenance indicators. This section aims
And in GB/T 29834.1 and GB/T 29834.3 combination.
Systems and software maintenance
Part 2. Measurement Methods
1 Scope
This section GB/T 29834 on the basis of GB/T 29834.1 proposed index system, provides for maintenance of the system and software
The amount of formula.
This section applies to all types of systems have maintenance requirements and software. Without this period does not apply to "single-use" or in use
Systems and software changes.
NOTE. The system referred to in this section are primarily software system.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein
Member. For undated references, the latest edition (including any amendments) applies to this document.

3 Terms and Definitions
Terms and definitions GB/T 11457 and GB/T 29834.1, as defined in this document apply.
4 Overview
Maintenance is an important quality systems and software features. System maintenance and software to measure, help us to understand whether the software
Meet the requirements of maintenance requirements, it is conducive to the demand side, developer, and other timely detection, localization maintenance defects. According to GB/T 29834.1 Suo
The definition of index system, using appropriate methods and formulas to measure each indicator, comparable quantitative values \u200b\u200bobtained.
Before implementing measure, the relevant measure should be stated in advance objects (such as modules, function) granularity.
This section presents a set of software and GB/T 29834.1 use with a measure of the quality of maintenance. Users should be from GB/T 29834.1
Select the maintenance indicators, measure and determine the appropriate test methods in accordance with specifications.
For one particular system or software, can be both complete maintenance, it could be for a part of system maintenance. Therefore
To select the corresponding appropriate indicators for the specific objectives of its maintenance, improve maintenance of the measure of accuracy.
a) to obtain the source code and software system, you can remove the index system metrics for the code;
b) For this maintenance function point completely unrelated, when measurement can give up;
c) For other indicators can not measure, you can give up a measure.
Analysis of 5 Yi
5.1 Failure diagnosis efficiency
The failure diagnostic efficiency and accuracy indicator comprises two time failure diagnosis of the failure diagnosis, as shown in Table 1.
