Data processing-Vocabulary
Section 14: Reliability,
maintenance and availabilityUDC 681.3
GB 5271:14--85
This vocabulary consists of about twenty parts. This part specifies the commonly used main concepts of reliability, maintenance and availability in data processing.
This part of the vocabulary is equivalent to the international standard ISO2382/14 "Data processing vocabulary--Part 14: Reliability, maintenance and availability" (1978 version).
1.2 Scope
This vocabulary selects the terms and concise definitions of some concepts in the field of data processing, and clarifies the relationship between different concepts for the purpose of domestic and international communication.
The vocabulary covers all major aspects of data processing, including the main processing processes and the types of equipment used, data representation, data organization, data description, computer programming and operation, peripheral equipment, data communication and other special applications. 1.3 Scope of application
This standard applies to the design, production, maintenance, use, management, scientific research, teaching and publishing of various fields related to electronic computers and information processing.

14 Reliability, maintenance and availability
14.01 Reliability and failure
14.01.01 Reliability
reliability
GB 5271.14--85
The ability of a functional component to perform a specified function under specified conditions and within a specified time. 14.01.02
mean time between failures
MTBF(abbreviation)
The average duration between successive failures of a functional component under specified conditions within its specified life span. 14.01.03
mean time to repair
mean time to repair
MTTR (abbreviation)
Mean time required to perform corrective repairs on a functional unit within its specified life span. 14.01.04
(Human) error
mistake
A human action resulting in an undesirable result.
A contingent condition that renders a functional unit incapable of performing its specified function. Failure
failure
The loss of the ability of a functional unit to perform its specified function. Program-sensitive fault
program-sensitive fault
A fault caused by the execution of certain specific sequences of instructions. 14.01.08
Data-sensitive fault
Data-sensitve fault
A fault caused by the processing of a specific data pattern. 14.02 Repair
Repair, maintenance
maintenance
Any activity that maintains or restores a functional unit to a state in which it can perform its specified function. Note: Maintenance is the activity, such as testing, measuring, replacing, adjusting and repairing, that keeps a functional part in a specified condition. 14.02. 02
Maintainability
maintainability
The degree of difficulty in making a functional part capable of being maintained in accordance with specified requirements. Corrective maintenance
corrective maintenance
Maintenance designed to eliminate existing faults. 14.02.04
Preventive maintenance
preventive maintenance
Maintenance designed to prevent faults from occurring. 234
scheduled maintenance
GB5271.14-85
Maintenance performed according to a planned schedule.
Marginal test
marginal test
marginal check
marginal check
A technique of varying certain operating conditions (such as changing the supply voltage or frequency) around nominal values ​​in order to detect and identify parts that may fail in the future.
Interval
Available time
available time
The time during which a functional component can be used from the user's point of view. 14.03.02
Unavailable time
unavailable time
The time during which a functional component cannot be used from the user's point of view. 14.03.03
Operable time
operable time
uptime
The portion of time during which a functional component can be used to obtain correct results. Inoperable time
inoperable time
When all environmental conditions are met, if the functional component works but cannot obtain the correct result, the part of the downtime.
Operating time, working time
operating time
The part of the operable time when the functional component is operated. 14.03.06
Idle time
idle time
The part of the operable time when the functional component is not operated. Downtime
down time
The time when the functional component cannot be used due to a fault. Note: Downtime may be caused by a fault in the functional component itself or by an environmental fault. If it is the former, the downtime here is equal to the inoperable time. 14.03.08
external loss time
external loss time
environmental loss time
environmental loss time
downtime due to failures other than those of functional components. 14.03.09system production time
system production time
the portion of operating time actually used by the user. 235
program production time
program production time
the portion of system production time during which the user's computer program can be successfully executed. System test time
system test time
the portion of operating time during which functional components are tested to determine whether they can work correctly. Note: Since a functional component may consist of a computer and its operating system, sometimes system test time includes the test time of a computer program that belongs to the computer operating system.
program test time
program test time
the portion of system production time during which the user's computer program is tested. Repeat run time
rerun time.
The portion of operating time that is repeated due to malfunction or human error in operation. Miscellaneous time
miscellaneous time
incidental time
The portion of operating time other than system test time or repeated operation time. In addition to system production time, the U.S.
Note: Miscellaneous time is mainly used for demonstration performance, operator training or similar other purposes. Total
Operable time -
Fault downtime -
