Introduction
This section GB/T 29832 with reference to GB/T 16260.2-2006 "Software engineering - Product quality - Part 2. External metrics" with
Body given the system reliability and the quality of software metrics and measurement formulas.
The method set forth in this section is not a complete set, is still exploring new methods not included. Reliability testing personnel from
In this section select the appropriate method for single or multiple combinations of methods for measuring the reliability of the system under test quality situation; to be
Modify or use other methods not covered in this section.
This section applies to a variety of computer software products and related systems with reliability requirements, but not every measure for a variety of meter
Computer software products and related systems, and in this section assumes that the tested software and related systems have been running for some time, it has been subjected to function
Test.
The main users of this standard is expected to include.
a) the demand side (obtained from the supplier or procurement system, software product or software service individual or organization);
b) the evaluator (individual or organization to implement the evaluation);
c) the supplier (the contract provided by the system, organization or individual software product or software service to the acquirer), which is indeed the eligibility test
When using recognized software quality.
GB/T 29832.1 "Systems and Software Reliability - Part 1. Indicator System" gives the system reliability index,
GB/T 29832.3 "Systems and Software Reliability - Part 3. Test methods" describes the test method for reliability index. This section aims
In conjunction with the GB/T 29832.1 and GB/T 29832.3.
Systems and Software Reliability
Part 2. Measurement Methods
1 Scope
This part of the basis of the index system GB/T 29832 in GB/T 29832.1 presented on the provisions of the reliability of the system and software
The amount of formula for demand-side system and software evaluator for the parties to provide a uniform measure of reliability.
This section applies to systems and software reliability requirements of reliability test and measurement.
NOTE. The system referred to in this section are primarily software system.
